I bought for my 03 avalanche with 5.3 and it gave me the little boost or pep that I was looking for and was easy to install took maybe half hour and very simple .

The K&N 77 series cold air intake is very well made and takes apps. 1 1/2 hours to install. As long as you have a good mechanical ability there will be no problem installing. It has proven very good from a dead stop with instant pick up as well as on the highway. Don't believe there has been an increase in gas mileage due to getting on it more and enjoying the extra power. Rule of thumb for me is more hp less gas mileage. I believe you will be satisfied with this purchase and I have no regrets with the purchase. I have purchased many things in the past from Autoanything and they are GREAT to deal with!

I love this new intake. I feel like I'm getter mileage but will not get a good baseline for anoher month. the 1st fill up showed about a 1.5 MPG increase. That alone will pay for this unit in about 7 months on the outside. The one concern I have is that now the intake is open on all sides. Living in Nashville where the floooding is still in te front of my mind, I cannot run in very deep water at all compared to stock. If that is not a concern for you then this intake rocks!!
