LS1 Camaro & Firebird Smooth Bellow Intake Coupler

New intake coupler that goes between the Mass Air Flow sensor (MAF) and throttle body. Gains some horsepower and adds looks under the hood. This piece replaces the restrictive accordion-style factory bellows, straightening out air flow between the MAF sensor and throttle body for an increase of up to 9 horsepower. A single-rib design allows adequate flex while posing minimal restriction. The smooth bellows is made from high quality, fiberglass-reinforced silicone.
