Specs & Features

• Double the Volume: Built around a premium Garrett Core measuring 26.2" x 7" x 4.25"—that is 101% larger than the factory unit, turning the front end into a massive heat sink.
• Flow Optimized: Features Cast Aluminum End Tanks designed to disperse air evenly across the entire core, maximizing cooling efficiency without hurting throttle response.
• Billet Support: Since this core is a beast, COBB includes bespoke Billet Aluminum Upper Mounts and new bushings to support the extra weight securely.
• No-Choke Piping: Includes 2.5" Mandrel-Bent Aluminum Charge Pipes finished in wrinkle black, connected by custom silicone couplers and constant-tension clamps for a leak-free boost path.
• Plug-and-Play Power: Engineered to install easily (zero mods for FL5, minimal for DE5) and works perfectly on the Stock Tune or COBB OTS Maps.

Product Description

The FL5 Civic Type R and DE5 Integra Type S are incredible track weapons, but they have a common enemy: heat. While the factory intercooler flows decent air, it lacks the thermal mass to keep up with the turbocharged K20 engine during extended abuse. Once heat soak sets in, the ECU pulls timing, and that sharp Honda response turns sluggish. The COBB Tuning Intercooler Kit is the solution, acting as a massive thermal battery to keep intake temps pinned near ambient.

COBB didn't just go slightly bigger; the engineers went huge. By utilizing a high-density Garrett Core, this system offers more than double the volume of the stock unit. This massive increase in surface area sheds heat rapidly, ensuring the engine gets dense, oxygen-rich air whether sitting in traffic or chasing a personal best at the track.

A core this big is significantly heavier than the flimsy stock aluminum/plastic combo. Most brands just let it hang on the factory tabs. COBB provides unmatched attention to detail by including Custom Billet Upper Mounts. These sturdy mounts ensure the intercooler stays rock-solid, preventing vibration or sagging over time.

It’s not just an intercooler; it’s a full system. The kit replaces the factory rubber hoses with Wrinkle Black Aluminum Piping that won't expand under boost. The custom silicone couplers and constant-tension clamps ensure that boost leaks are a thing of the past. For FL5 owners, it’s a direct drop-in with no cutting. For DE5 owners, only minimal modification is needed to clear the massive core.

This is the foundational upgrade for the modern Type R and Type S platform. It provides the cooling overhead needed for consistent power now, and the flow capacity required for big turbo upgrades later. Whether sticking to the stock tune or flashing a COBB Stage 2 map, this intercooler ensures the car delivers reliable, consistent power every time the throttle hits the floor. Trust the K20 to COBB.
