Review on Duramax LLY 2004.5-2005 Chevy Silverado GMC Sierra 🚙 6.6L Diesel Turbo Inlet Manifold Intake Elbow (Part No. 76-1006B) by Kevin Baker

Easy installation. I couldn't line up the PCV hose with the new inlet. Afraid of breaking it, I went ahead and took a detour. While in Taxifornia I may have to come up with a plan during the SMOG sight test. It's only about 15% larger if you count it, but I don't think that would help since the turbo inlet was the same diameter (or very close) as the original inlet. A bigger turbo along with a new intake manifold would have been the right decision. Didn't notice any difference in performance at all. Temperatures were the same, my gauge has been up to 190 since day one. Maybe I'll notice it when towing. The ratings are blank as I didn't ride enough to notice an increase in MPG.
