Fleece Performance 2017-2019 Chevrolet/GMC 2500/3500 High Flow Intake Horn (6.6L) FPE-L5P-INTAKEHORN

Fits 2017-2019 Chevrolet Silverado and GMC Sierra 2500/3500 HD (6.6L L5P Duramax).

The Fleece Performance High Flow Intake Horn is a direct-replacement performance upgrade for the restrictive factory intake runner. While the stock plastic component features a narrow 2.4-inch diameter, this Fleece Performance version utilizes a larger 3.3-inch cast aluminum bore to significantly reduce intake restriction and improve turbocharger efficiency. This design optimization can result in gains of up to 10 additional rear-wheel horsepower (RWHP).

Engineered for a seamless installation, this intake horn bolts directly to the factory mounting points and requires no aftermarket tuning or modifications to the vehicle. The kit includes a billet aluminum fitting for a secure PCV connection and a square-cut O-ring to ensure a leak-free seal under boost.
