I'm not sure how it would work out on your truck. I did alot of research on intakes for My 07 Impala and found one on ebay motors.. I did not get the K&N and went with a generic brand.. this work better than name brand, I think, because if you thing about it, the end cap on the K&N is a flat metal disc, as some of the generic have a concave filter on the end cap to increase more air flow.. Also you will be looking to spend about $300 on K&N when you can get one from ebay sometimes less than $100. How much gas do you have to save to make up the differance?? On the 07's you will not like it the first few 100 miles or so because the computer has programed itself the way you drive and the equipment it has. It will re-learn everything again.. I have seen about 3.5 MPG increase so far.. My car is still in the learning mode as well. I don't know about the horse power yet, but it does sound nice..
Hope this helps.
