Designed for this application, this is not a cobbled-together mess. The intake is one of the most visible things you'll see underhood!
LSx engines are very sensitive to intake air temperature, so we've kept that to a minimum here. A special baffle isolates the air filter from the underhood heat and allows it to pull from outside the engine bay. As a bonus, the GM PCM is mounted to the baffle so it is also not affected by heat. It's even spaced off the baffle for full air circulation.
A custom silicone intake hose snakes out of the throttle body into a MAF adapter of the correct diameter and length for the best readings. The air filter has a 4" inlet. The whole thing comes with all the fasteners and gaskets and hose clamps you need.
Requires the removal of the stock washer bottle. Not compatible with the Fiat 124.
