2004.5-2005 Duramax Deluxe Max Air Flow Bundle (284-HSP)

Fits

This turbo mouthpiece will give you the ability to reroute your factory PCV system and remove the factory resonator box, eliminating unwanted engine oil gumming up the turbo and intake system. Featuring 3" mandrel bent hot side and cold side tubes with our easy-to-install two-piece Y-bridge with race-proven 5-layer silicone boots so you can be ensured a great fit that won't let you down.

This 3" cold side tube will ensure your engine gets all the air it wants. This bolted-together two-piece Y-bridge will make installation a breeze and ensure a leak-free seal that won't leave you stranded on the side of the road. To help get the exhaust gases out of the engine, this kit includes our factory replacement 2" up pipes. These up pipes use .120" wall tubing with the toughest bellows on the market to ensure they last as long as your truck.
