2010 suburban 5.3 super easy install. If you have the tools and the know how 40min tops. Runs nicely no general change in milage but a noticeable change in peddle response. Stock intake runners have huge plenums to reduce noise and seem to make it the peddle a little sluggish if you're looking for it.

ممتاز

bought this to replace my factory intake with the drop in filter i like the added sound on it i also have a Borla s type single in dual out no tuner since i didn't like it and returned it was only running regular fuel tune. i also bought a filter wrap for it gives 2 years of water repellent protection and extra dirt protection just slides over the filter mounted on a 09 Sierra 4.8L might lose fuel economy but oh well gives extra sound dont know if it gets extra power but not like it matters im driving a 4.8 4 speed lol its got speed but not compared to my friends trucks

Easy installation, great sound and overall my truck seems to drive better.
