Specs & Features

• Massive Heat Sink: Features a gargantuan 30" x 10.35" x 3.5" Bar and Plate Core that dominates the front bumper, available in Stealth Black or Flash Silver.
• Speed Density Ready: The cold-side charge pipe comes with a pre-welded Integrated IAT Bung, making the switch to Speed Density tuning a plug-and-play affair for pro tuners.
• STI Specific Extras: The STI kit goes further by including the COBB Universal LF BPV and a custom Coolant Overflow Tank to solve tight engine bay fitment issues.
• WRX Flexibility: The WRX kit is designed to work with either the stock plastic bypass valve or an upgraded COBB BPV, keeping the upgrade path flexible.
• No-Lag Piping: Utilizes 2.5" Mandrel-Bent Aluminum Tubing finished in wrinkle black, the perfect diameter to maintain throttle response while flowing enough air for 800+ WHP.

Product Description

If you drive a 2008-2014 WRX or STI, you know the struggle: you sit in traffic for five minutes, the hood scoop stops feeding air, and the factory Top Mount Intercooler (TMIC) turns into a radiator. The moment you hit the gas, intake temps skyrocket and the ECU pulls timing. The COBB Tuning Front Mount Intercooler solves this by evicting that heat-soaked brick and moving the cooling core straight into the wind.

This isn't a flimsy tube-and-fin core. COBB uses a dense, heavy-duty 3.5" thick Bar and Plate core. It acts like a giant thermal battery, keeping Intake Air Temps (IATs) near ambient levels even during back-to-back pulls. Drivers can choose the Black finish for a stealthy "sleeper" look (featuring a thermal heat-dissipating coating) or the Silver finish to show off that metal behind the grille.

Once a Subaru goes big turbo or big power, the stock Mass Air Flow (MAF) sensor often becomes a restriction. That’s why COBB pre-welded a bung for an Intake Air Temperature sensor right into the charge pipe. This makes converting to Speed Density tuning straightforward—no drilling or welding required.

Model Specific Details

• For the WRX (08-14): This kit is streamlined to reuse the factory BPV or accept an aftermarket replacement, keeping costs down while delivering maximum cooling.

• For the STI (08-14): The STI engine bay is tighter, so COBB includes the hardware to make it fit right. This includes a Coolant Overflow Tank relocation kit and the legendary COBB LF Bypass Valve, ensuring the boost system holds pressure reliably.

This is the most well-thought-out FMIC kit on the market for the GR/GV chassis. It eliminates the infamous Subaru heat soak, preps the car for advanced tuning with Speed Density support, and includes the relocation hardware other brands forget. Whether building a track weapon or a street sleeper, the COBB FMIC ensures the EJ engine gets the dense, cold air it needs to make maximum horsepower.
