Evolution at its Best
The S&B 76-1006B Turbo Inlet Manifold for your 2004.5-2005 GM 6.6L Duramax went through dramatic changes from the powder coated black 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 that utilizes the stock location and out performs the competition.

Increase Your LLY's Performance
When installed our turbo mouthpiece will increase throttle response and help lower you engine's EGTs keeping your engine running at cooler temperatures.

Simply Better
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. 

Threaded CCV Port Gives you Options

Worth the $$$

This was worth it for me. The instructions are very detailed and nothing is left out. Took me about 45 minutes. Hardest parts for me were getting the clamp to let go of the hose on the CCV port of the old inlet, as well as getting the new inlet down in there (it's a very tight squeeze, but you wiggle it around it will go in there) and centered while trying to tighten up the v-band clamp. I noticed it helps keep the engine a little cooler and has helped with fuel economy (maybe 1 mpg). It also seemed to help with acceleration and shifting. When I would go around a corner and let off, then accelerate again, it would be kind of rough if it had to shift. Not sure if it was something with the whole vacuum thing and turbo lag or what, but it shifts a lot smoother now. It never used to be that way until I installed a 4 in. straight exhaust from the downpipe back. Fixed now though and worth it!
Easy Installation

Installation was a snap. Total time was only about 30 minutes. It really cleans up the engine compartment. I noticed minor performance gains, but nothing too extravagant. I don't regret the purchase.
