Cervini's Ram Air Kit (338A) - 1988-1995 GMC Sierra 5.0L & 5.7L
Unlock additional performance from your GMC truck with the Cervini's Ram Air Kit. Designed specifically for 1988-1995 GMC Sierra models equipped with 5.0L or 5.7L V8 engines, this system channels cooler outside air directly into the intake tract, helping improve throttle response and horsepower at speed.
Using onboard diagnostic testing, Cervini's demonstrated gains of up to 0.3 seconds and 3 mph in quarter-mile performance. By feeding cooler, denser air into the engine, the Ram Air Kit helps improve acceleration and overall responsiveness. Performance benefits begin around 40 mph and continue through 70 mph and beyond, making it an excellent complement to performance-oriented street trucks and sport truck builds.
Installation is straightforward and requires only minor modification to the factory air box. Simply remove the air box, use the included template to cut the opening, and install the supplied cover plate. When purchased with a compatible Cervini's Ram Air Hood, the duct can be pre-installed on the underside of the hood for even easier installation.
