Would have gave this 5 stars but the product wasn't cut/made for the specks of my truck, had to drill out the existing hole already there to get my sensor to fit, also not seeing an increase in gas improvement either, other than those 2 things think my truck likes breathing better lol.

Intake took about 90 min. to install. Instantly noticed increase in power. Intake has a great sound that my Trailblazer didn't have before. I would recommend this air intake to anyone looking to update their air intake system.
