What is the difference between the PRL Tube and Fin Intercooler Upgrade for FL5 and the PRL Bar-and-Plate Intercooler?

The two intercoolers use the same core dimensions and fill the same space in the OEM front bumper, but they perform differently depending on how the car is driven. The bar-and-plate starts cooler on early pulls, beginning at around 86°F with minimal rise through the first two pulls, making it the stronger choice for drag racing or short-burst street use where the dense thermal mass absorbs heat quickly. The Intercooler Upgrade for FL5 starts 5 to 10°F higher on those early pulls due to its lighter construction and reduced thermal mass, but as sessions continue it outperforms the bar-and-plate, stabilizing at 160 to 170°F compared to the bar-and-plate's plateau around 190°F. For sustained track sessions, road racing, endurance driving, or any use where airflow is continuous and heat management over time matters more than single-pull performance, the tube and fin is the more capable option. It is also 7.8lbs lighter at 14.4lbs versus 22.2lbs for the bar-and-plate.

Does the Intercooler Upgrade for FL5 require any modifications to install?

Yes, some minor modifications are required. Installation involves relocating the ambient air temperature sensor by cutting or trimming the factory mounting tab, removing the air dams on the bumper, and drilling a hole in the air dam for clearance. New custom EPDM O-rings are included in the kit, so the factory charge pipe O-rings do not need to be modified. Full installation instructions are provided by PRL Motorsports.

What does the black thermal dispersant coating actually do, and is it worth it?

The black thermal dispersant coating is applied to the exterior surfaces of the core and is designed to improve how heat moves across and away from the intercooler during driving. Instead of concentrating heat at localized hot spots, the coating spreads thermal energy more evenly across the entire core surface, allowing a greater percentage of the core to actively release heat into the airstream at any given moment. The practical benefit is faster thermal recovery between pulls and improved consistency during extended sessions where temperatures stay elevated. It also adds corrosion resistance and surface protection. For primarily street use, the standard version is sufficient. For back-to-back track sessions or endurance events where recovery speed between corners and straights matters, the coated version has a measurable advantage.

Is the PRL Tube and Fin Intercooler Upgrade for FL5 as durable as the Bar-and-Plate version?

The tube and fin design is rated at approximately 75% of the bar-and-plate's durability. PRL describes this as still excellent for street use, but notes that the thinner tube walls that make the design lighter and more thermally efficient are also what reduce its impact resistance compared to the denser bar-and-plate construction. For road racing, endurance sessions, and performance street driving, durability is not a practical concern. For off-road or applications with higher risk of physical impact to the front of the car, the bar-and-plate's greater structural density may be a better fit.

Does the PRL Tube and Fin Intercooler fit without removing the bumper?

The intercooler uses the same core size as the PRL bar-and-plate unit, which was engineered to maximize the available space inside the OEM front bumper. While it fits within the factory bumper opening without cutting the bumper itself, installation does require bumper removal to access the intercooler mounting area, along with the ambient temperature sensor relocation and air dam removal mentioned above.

Is the PRL Tube and Fin Intercooler CARB compliant?

The product is currently under CARB review. Confirmation of CARB compliance status will be updated once the review is complete. Customers in California or other states following CARB standards should confirm the current compliance status before purchasing.

What vehicles does the PRL Tube and Fin Intercooler fit?

The PRL Tube and Fin Intercooler Upgrade for FL5 fits the 2023-present Honda Civic Type R (FL5) and the 2024-present Acura Integra Type S (DE5). It uses OEM mounting points and is engineered to fit within the factory front bumper opening without bumper modification.

Description

PRL Motorsports Tube and Fin Intercooler Upgrade for FL5 Honda Civic Type R and DE5 Acura Integra Type S

PRL’s Tube and Fin Intercooler Upgrade for FL5 Honda Civic Type R and DE5 Acura Integra Type S is the lightest, most thermally efficient core in their 2.0T lineup, engineered for drivers who run repeated hard pulls. The tube-and-fin layout uses thin-wall oval tubes with internal fins to move heat out of the charge air faster than a bar-and-plate core, while CNC-machined billet end tanks shave significant weight versus PRL’s own billet intercooler. Total assembly weight comes in at 14.4lbs, about 35% lighter than PRL’s 22.2lb bar-and-plate, with no compromise to OEM-style sealing or charge pipe compatibility. Available in raw billet aluminum or with PRL’s black thermal dispersant coating, the Intercooler Upgrade for FL5 adds surface heat shedding and corrosion resistance for street and track use.

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.
