This HPS Performance Cold Side Charge Pipe Kit replaces the stock OEM plastic cold side charge pipe as an essential upgrade. The 3.5" stainless steel custom mandrel-bent tube allows more air to flow into your engine while drastically reducing EGT’s. This kit features 4-ply reinforced oil resistant fluoro-lined silicone boots designed to resist the damaging effects of oil blow-by commonly found in the 6.6L Duramax Diesel LML engines. Also included in the kit are stainless steel spring-loaded T-bolt clamps that accommodate for fluctuations in temperature and pressure during operation without risking boost leaks.
