Introducing the new CNC Machined Turbo Mouthpiece for the LLY Duramax.
Our new turbo inlet went through dramatic changes from the powder coated white body of the mouthpiece to the CNC machined edges giving your engine the look it deserves. Not only does it look great under the hood but it's also compatible with any intake system and out performs the competition.
When installed our turbo mouthpiece will increase throttle response and help lower you engine's EGTs keeping your engine running at cooler temperatures.
When tested to the ISO 5011 standard the S&B mouthpiece out performs both aFe and the LBZ mouthpieces with a 78.6% increase in air flow over the stock LLY Mouthpiece.
In order to remain compliant with current emissions regulations we designed a threaded CCV port. We included a plug for all of those who wish to re-route the CCV tube for race only installations.
