The installation would have been easier if the hose that attaches the unit to the engine was 1" longer.

Purchased a K&N series 77 from AutoAnything. Easy to install took about 45 min, got it for a great price also. looks great in my 2004 Hummer H2. I did see and feel the improvement it gave me, the horsepower and torque. Sounded very good also when I step on it. Thank you AutoAnything

Easy to install. No idea about any extra HP or gas milage. I have only been doing short city driving. My commute to work is no more than 10 miles a day. I will have to wait a bit until I can make a decent highway trip to see if my milage improves. Overall, I am satisfied.
