Description

CSF High Performance Charge Air Coolers for G90 M5 & G99 M5 Touring [8351]

Engineered for the demands of BMW’s new G90 M5 and G99 M5 Touring, CSF’s High Performance Charge-Air-Coolers address a critical bottleneck on the S68 platform. With the S68 already proven to deliver 900+ whp on stock internals, the resulting heat and pressure can overwhelm the fragile factory coolers. CSF resolves this limitation by revising its proven S63 / S68 charge-air-cooler design specifically for the G90 / G99, delivering greater durability and thermal headroom to support elevated power targets. Finished in an OEM+ Crinkle Black, these units blend seamlessly with the engine bay while providing the robustness and efficiency required for consistent, reliable performance.

OEM vs CSF

CSF’s charge-air-cooler cores offer approximately 100% greater volume than the factory units. Designed through CFD analysis and validated in testing, the cores deliver optimal performance with precise fitment. Both coolers feature OEM-style quick-connect water fittings and integrated sensor ports for fast, straightforward installation. For additional details and performance data, see the full press release on the CSF #8178 coolers.
CSF replaces the weak OEM crimped plastic end tanks with larger, CFD-analyzed, 100% TIG-welded cast units. The charge pipe is integrated into the upper end tank, eliminating the glued-on factory plastic charge pipes and creating a single-piece cast assembly engineered to withstand substantially higher boost pressures. For added versatility, dual 1/8″ NPT ports are incorporated on both outlet-side air tanks, enabling quick installation of aftermarket methanol or nitrous injection. These ports are strategically positioned to introduce the injection directly into the post-intercooled charge-air stream for maximum performance.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

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.

BP Pricing Difference

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.
