This is not my first K & N filter that I have had in my vehicles. I have relied on the K & N filter quality to help the engines in several of my vehicles breath & operate properly for many years. The new filter that I just purchased for my Chevy Silverado turbo charged DuraMax diesel is the first of the cone shaped filters & so only time will tell me just how good this one is. I can only assume that it will live up to my expectations of the overall K & N product quality that I have always found to be true. Don

It was time to replace the air filter in my truck. I found that the OEM replacement filter was the same cost as a K & N permanent filter. I would have gone with the K & N anyway, but this was a no brainer. I always recomend K & N filters or even the intake kits, they are great products.

I have had a K&N on my Dodge Cummins for years and had good service so it only made sense to put one on my Chevy Duramax and I have seen slight improvement on mileage.

A friend who also drives a Chevy Duramax swears by the K&N replacement filter he runs on his truck so I thought I would give it a try. I tend to not baby the truck and push it hard even in traffic and there is a noticable increase in acceleration with the new filter. The open-road mileage is up over 1 mpg so it is going to save me some cash on the open road and like the diesel motor, it is built for the long haul. Get yourself one and prove it for yourself!

I have owned many K/N air filters over the years. That is why, when I bought my new GMC diesel pickup, the first thing I did was purchase a K/N air filter. K/N lets my tow beast breath deeply, I know it will improve mileage. I like the fact that I can clean it anytime anywhere, and drive on. Plus, being an old gearhead, I love the noticable extra kick in the pants you get on a, lets say, spirited take off. When I get a new set of wheels, the first thing is a new K/N air filter, no shopping around. This is a product that has proven its worth every time.

The air filter fits really tight, which is a good thing. I tried several times, to install air filter, unsuccessfully, until I finally used the tube of lubricant, which is included in shipping box. I haven't had a chance to drive my truck any distance, yet, to see if the fuel economy or overall performance is going to improve. My truck is a 2008 Chevy Silverado HD3500, 6.6 duramax diesel, crew cab, 8 foot box, 4 wheel drive, dually.

I HAVE USED K&N IN TRUCKS OVER THE YEARS AND HAVE ALWAYS HAD GOOD RESULTS. THE DESIGN'S ARE NEAR PERFECT AND I HAVE AWAYS NOTICED THE RESULTS. I OF COURSE TESTED MY 07 DURAMAX BEFORE I INSTALLED THE K&N AND AFTER. I WAS HAPPY AS IN THE PAST WITH MY FORD AND DODGE INSTALLATIONS. THE POWER GAIN WAS NOTICED IN STOCK SETTING OF MY BULLY DOG PROGRAMMER. AND THE FUEL SAVINGS HAS BEEN 1.5 TO 3 MPG. I INSTALLED THE K&N INTO A COLD AIR INDUCTION BOX THAT I DESIGNED. AT 55 MPH MY BEST AVG. HAS BEEN 28.2 MPG. AND AT 65 TO 75 MPH I STILL GET 20 TO 23 MPG. WITH THE K&N AND THE BULLY DOG IN PERFORMANCE MODE. 90 HP ADD SETTING. THANK YOU K&N AND KEEP UP THE GOOD WORK.

The K&N Air Filter was very easy to install. It took me less than 10 minutes from the time I started to remove the screw on the air filter compartment. I just returned home from a fishing trip to Central British Columbia. My pickup has more power and does not work as hard to get to cruising speed as it previously did before I installed tne new K&N Air Filter. I am now waiting to see if my fuel consumption improves. The fact that the K&N Air Filter is permanent, will save me money by not having to purchase regular air filters. So, as far as I am concerned I am already ahead even if the fuel consumption does not improve. Thank you for the easy to follow instructions!!! Clarence

Installed this filter to replace the stock element on my '07 GMC Duramax LBZ. It made a very noticeable increase in power and throttle response, while greatly reducing black smoke under hard acceleration. There was no increase in noise. For $51 this is the best upgrade you can make.

The airbox lid would not completely close due to several "fins" needed to keep the stock filter in place. I noticed an immediate difference in performance but I lost about 2 mpg. Overall I am not happy with this filter and I would highly recommend to keep your motor stock.
