CSF Charge Air-Cooler Manifold for BMW B58 Engine (Gen 1) [8300]

CSF’s Gen 2 B58 “Super Manifold” for G-Chassis BMWs and Toyota Supra has sold over 450 units, earning widespread acclaim for its industry-leading design and performance. In response to strong demand, CSF now introduces the “Super Manifold” for the Gen 1 B58 F-Chassis BMW platform. The Gen 1 B58 Charge-Air-Cooler Manifold features the same advanced design and specifications as the Gen 2, along with improved fit and finish. As Gen 1 B58 vehicles grow in popularity among tuners and motorsport enthusiasts, the demand for high-performance parts has surged, especially for cars exceeding 600 horsepower. The “Super Manifold” addresses the shortcomings of the OEM system, such as heat soak, limited durability, and failures under high-boost conditions, making it the ultimate solution for power and reliability.

Design and Engineering

During the development of the Charge-Air-Cooler Manifold for the Gen 1 B58, CSF collaborated with R&D partner VF Engineering to conduct extensive dyno testing. Over 50 runs were performed on the same car, under consistent conditions (~90°F ambient temperature), comparing the performance of the CSF Charge-Air-Cooler Manifold to the OEM unit. Each system underwent approximately 25 back-to-back pulls at 30-second intervals, assessing heat soak resistance, recovery time, long-term performance, and turbo system duty cycle. This rigorous approach to R&D underscores CSF’s commitment to delivering exceptional products. The Gen 1 B58 Charge-Air-Cooler Manifold, which builds on the proven design of the Gen 2 manifold with minor fitment adjustments, offers the same level of unmatched performance. The Gen 1 B58 “Super Manifold” has been battle-tested in the world’s most demanding motorsport events, including the Pikes Peak International Hill Climb, Global Time Attack, and Texas 2K drag racing. It has also demonstrated its capabilities on dynos, supporting vehicles producing over 1000 whp. While the manifold’s advanced features and engineering excellence set it apart, its proven performance in real-world applications truly speaks for itself.
Summary of Testing:
- Faster recovery of intake air temperatures
- 30°F reduction of intake air temperatures (IAT’s) compared to OEM
- Less pressure drop compared to OEM core
- Puts less stress on the turbo system, allowing more boost to be made at higher targets
- Avoided going into limp mode after prolonged demanding conditions, simulating motorsports use
- On a stage 2 car with bolt-on upgrades, making ~400whp (with no port injection), comparing dyno run 19 between CSF and OEM, an increase of ~26whp and 11wtq were achieved
- The performance increase and delta between CSF and OEM will be larger as power is increased in the vehicle

Top Feed Port Injection with Included Fuel Rail

The CSF Manifold features an extruded fuel rail designed to attach seamlessly to the outlet side of the manifold. The AN-8 fuel rail includes feed and return -8 internal hex plug fittings from Radium Engineering, ensuring a plug-and-play installation. Each cylinder fuel rail aperture is optimized with a 7mm opening, providing compatibility with most high-performance injectors. CSF recommends Injector Dynamics (ID) injectors for optimal performance. To support the use of short-height injectors, also known as “shorties,” the supplied hardware kit includes anodized CNC-machined injector hats (set of 6) for precise fitment and functionality.

Vacuum and Parameter Pad

CSF has integrated a 3-port pad into the machining of the tank on the manifold inlet side. These 1/8″ NPT ports provide flexibility for measuring additional parameters or serving as an extra vacuum source. If unused, the ports can be securely sealed using the plugs included in the hardware kit.

Easy Access to Spin-Off Oil Filter With Counter Balanced Design

CSF designed the manifold with a recessed section at the back to provide easy access to the spin-off oil filter, eliminating the need to remove the manifold during oil changes. While this design is not exclusive to CSF, CSF is the only company to address the airflow disruptions such a recess can cause. Using SolidWorks CFD software, CSF engineers developed and tested a counterbalanced protrusion positioned above the recess to offset airflow turbulence. This innovative feature ensures smooth air delivery to the rear of the core, optimizing cooling performance.

Air Inlet Divider

The CSF manifold includes an air divider welded into the inlet-side tank, an exclusive feature designed for optimal performance. To address the length of the manifold, CSF engineers, in collaboration with VF Engineering, ensured consistent air volume and velocity to all cylinders. After extensive simulations using SolidWorks CFD software, the air divider was incorporated to deliver equal airflow and cooling performance across the engine. This innovation ensures that cylinders four, five, and six at the rear of the manifold receive the same airflow as cylinders one, two, and three at the front, maximizing overall performance.

Breather Ports for Inlet/Outlet of Water Tanks

CSF has positioned two 1/8″ NPT ports on the top of the rear water plate, providing options for measuring inlet and outlet water temperatures or serving as breather ports during the bleeding procedure. The supplied hardware kit includes 1/8″ NPT plugs for unused ports. CSF recommends following the OEM BMW or Toyota bleeding procedure, which typically takes approximately 15 minutes to complete.

Thermal Rejection Competition Spacer

CSF exclusively offers the KIYLEX® Intake Manifold Spacer for the B58 motor, crafted from a patented, high-performance polymer as strong as aluminum and capable of withstanding temperatures up to 1100°F. This spacer is engineered to insulate the intake manifold from conductive heat transfer from the cylinder head, creating a thermal barrier that lowers manifold temperatures, reduces Intake Air Temperatures (IATs), improves charge air cooler efficiency, and combats heat soak. The Thermal Rejection Spacer is particularly beneficial for drag and roll-racing events, where vehicles often sit in staging lanes between runs. During these idle periods, insufficient airflow over the front-mounted heat exchanger leads to extreme heat soak, causing higher starting IATs on subsequent runs. By reducing heat transfer between the cylinder head and the manifold, the spacer helps maintain lower temperatures for more consistent performance. While the CSF manifold, made from billet aluminum and 100% TIG-welded, is designed for durability under higher boost pressures than the OEM plastic manifold, aluminum’s higher thermal conductivity can result in increased heat transfer. The Thermal Rejection Spacer mitigates this by absorbing heat from the cylinder head and dissipating it, rather than transferring it to the manifold. Designed for motorsports applications where optimal cooling is critical for a competitive edge, the CSF Thermal Rejection Competition Spacer also provides significant cooling benefits for any vehicle, enhancing overall performance and reliability.

Rear Water Plate Breather Ports & Overflow Tank Fitting

CSF has introduced a new -6 ORB 90° swivel fitting with adjustable clocking, offering greater flexibility for installing the overflow return line. This fitting allows the line to be routed directly to the OEM overflow tank in the factory configuration or hidden for a “clean-tucked” return route to the OEM overflow tank at the front of the engine bay. The kit includes 40 inches of overflow hose, which can be trimmed to the desired length for customized water line routing. Additionally, CSF has sourced and included an OEM quick-connect fitting for the factory overflow tank, ensuring a secure connection. For added convenience, the fitting comes pre-installed on the overflow line, enabling a quick and hassle-free installation.

Slotted Mounting Tabs

CSF designed the manifold for straightforward positioning within the engine bay. However, during test fittings, CSF identified that aligning the bolt holes on the intake-side mounting tabs could be challenging. To address this, the mounting tabs were slotted, allowing bolts to be loosely installed prior to making final positioning adjustments. This modification simplifies the installation process and ensures a smoother fit.

Core Differences

CSF sets itself apart by using a motorsports-grade bar-and-plate air-to-water core that is 100% larger (double the capacity) of the OEM core. This design features 12 cooling rows compared to the OEM’s 6 rows, delivering significantly enhanced cooling performance. In contrast, two competitors use the same core, which is only 70% larger than OEM and lacks published data on the number of cooling rows. Each intake runner on the CSF manifold is precisely machined to accommodate OEM O-rings, with factory-style “teeth” to secure them—an exclusive CSF feature. This design prevents O-rings from falling out during preparation and installation, significantly reducing frustration during the process. Additionally, the CSF Thermal Rejection Competition Spacer not only provides insulation but also serves as a gasket between the cylinder head and the manifold. Its precision machining ensures a perfect seal, enhancing performance and reliability. In comparison, a competitor’s phenolic spacer does not meet the same standards, requiring the use of aftermarket O-rings alongside the factory ones to achieve a positive seal between the manifold, spacer, and cylinder head.

Oil Filter Recess

While competitors have also incorporated a recessed design at the back of the manifold for easy access to the spin-off oil filter, CSF stands out as the only company to address the airflow disruptions caused by this feature. CSF engineers designed and tested a counterbalanced protrusion using SolidWorks CFD software, positioned above the recess to offset airflow turbulence. This innovation ensures smooth air delivery to the rear of the core, optimizing cooling performance for superior results.

About CSF

Back in 1947, a father and his three sons embarked on a business venture by setting up a small retail shop dealing in automotive parts. The family business blossomed over the years, evolving into an automotive garage specializing in radiator repair, and later, a radiator manufacturing facility. By 1975, the family-owned brand CSF was established, marking a milestone as the first to introduce import applications into the American automotive aftermarket, in line with the influx of Honda, Datsun, and Toyota vehicles. By 2009, the fourth generation of the CSF family joined the business, which had by then become a leading name in the import and domestic radiator and condenser markets, selling over 650,000 units that year despite an economic recession, and totaling over 35 million units to date. CSF’s portfolio expanded to include a diverse range of cooling systems, including commercial trucks, industrial and agricultural applications, marine coolers, intercoolers, pressure caps, and a pioneering Racing & High Performance Division. Today, CSF’s Racing & High Performance Division is renowned for designing and manufacturing advanced, efficient, and reliable cooling systems for a wide array of applications, from high performance all-aluminum direct-fit radiators to custom systems for racecars, power sports, off-road, marine, and industrial use. With over 50 years of experience and more than 40 million cooling systems sold worldwide, CSF has rightfully earned the industry title of “THE COOLING EXPERTS.”

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
