A K&N intake system belongs on all of your vehicles... A little pricey... I wish that this particular model had a cold air intake box and was completely enclosed . Very easy to install with instructions that are specific to your vehicle. So when you look at a picture in the instructions what you see in the background is what's really there...On my GMC Duramax I have to be honest and say I installed this right after purchasing it so I can comment on performance or mpg gains.

Easy install. I can hear the turbo whistle a little sooner now and when I step on it, it kind of sounds like a vacuum sucking air. It's a little early to tell exactly how much the milegae went up, but I do think I'm seeing an increase. Power seems better as well. I will recommend this to my friends.

Very easy to install. follow the directions and it only took about 30 minutes to install. Engine seems to respond much faster. Also installed a large bore exhaust system from AFE turbo back about 4 hours to remove and replace. Both wered purchased from Anythingauto. Very good price for both. Customer service from Anythingauto was beyond excellent. Should gain about 30 to 40 more horsepower from both and milage should be somewhere around 3 to 5 more miles to the gallon. adds up after a year of driving.

Well I haven't been able to do any testing with monitoring system in regards to HP increase or solid data on mileage, but I will give my initial views. 1st install was a breeze. Took about 45 mins to get the old box out and the new kit in and it would have been less time if I would have had an easier time getting the actual filter on the end of the tube (20 degree weather, ended up using a heat gun for flexibility). 2nd there were no problems once installed. Mass airflow sensor goes right back on along with oxygen sensor so no diagnostic issues. No leaks in the system and it did have a different sound as you could here the air bing sucked in. I have registered higher airflow then with the stock box, but it has been so cold that I can't really tell how much of a temp drop. And for the mileage I can't tell yet since there has been a lot of snow and use 4wd. When I have more data and quit playing with all the settings on my Hyperpac I'll update my review and if it all comes out as advertised I will change my rating to 5 stars. The only negative I had was the size of the hole the tube goes through where you mount the filter. I know there has to be room for engine movement, but it seems large enough that you can pull some hot air from the engine compartment. I might just make my own rubber gasket that fully seals it off from the engine compartment and still allow it to move a little.
