Excelente para Avalanche 2010 z71

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

Great product, easy install.

Sounds great. No change in fuel economy. The threaded nipple was missing, $5 part at the hardware store but inconvenient

Great product. Instantly felt a difference in acceleration and definitely noticed a difference on the highway plus the sound is incredible!
