The GReddy Performance Products Intercooler Kits offer state-of-the-art upgrades for your turbocharged 1.5L (L15B7) DOHC I4 engine in the Civic Sport Hatchback (FK7) and Civic Si Coupe/Sedan (FC3/FC1) for years 2016-2020. With the latest CARB EO D-397-12 certification, these kits are now street legal across all 50 states.

For 2020 models, fitment is assured although CARB EO coverage is pending.

Intercooler Kit Options:

• 12058100 (Type-31E): With core dimensions of L600 x H183 x W66 mm, this kit is perfect for stock turbos, boosting throttle response at lower speeds while providing a modest power increase. Median dyno results show gains of +4.53hp and +7.68ft/lb. peak.
• 12058102 (Type-28E): Larger with dimensions L600 x H248 x W66 mm, early models featuring welded sheet metal end-tanks, this kit is designed to elevate peak performance, ideal for both stock and upgraded turbos. It provides a significant horsepower boost with median dyno results of +14.53hp and +6.74ft/lb. peak, with a slight trade-off in low-speed throttle response.

Both kits include aluminum intercooler piping, hoses, and brackets. They're also compatible with the GReddy Civic Si/Hatch Oil Cooler kit, although the Type-28 may require minor modifications for optimal integration.
