It was very frustrating getting it in - wouldn't fit. Yes it is the right one. It gets 2 stars for being sturdy - I know, because the frustration led to it getting drop kicked across the shop. Probably not returnable as a result. GM gets a poor review for dinking up the air intake. My '03 Duramax air filters just dropped in, no problem. K & N will probably call it precise engineering. I call it just making life more difficult than it needs to be. I will still use K & N in my other vehicles but if you have an '08 Duramax I don't recommend it. Any product requiring that much aggravation won't get many stars. Open note to K & N: You guys build great stuff, I regret to say this one isn't your best work.

I normally put K&N filters on all my new vehicles for long term savings, possible mileage increase and extended maintenance. This filter, for an '06 Chevy diesel p/u, is really heavy duty. It took some effort to install, needs a very firm push while turning clockwise into it's holding tab. No doubts about the seal. So far I have not noticed an increase in mileage, but that would require numerous trips with similar conditions to be accurate. With improved mileage I'd rate it 5 stars.

I was so impressed after reading about the 1 Million Mile Warranty, I ordered this filter for my 2008 Silverado 2500HD, Duramax 6.6L. Amazon 's fast delivery had it to me in 2 days. I was heading on a 500 mile road trip, and hoped this would help with fuel economy and performance. WRONG!
Three miles down the road and the warning lights started, Engine Lost Power, Change Air Filter, Service Engine Soon, and then I was on the side of the road.
Called H&N, the rep stated that "some '08 Duramax will not except this filter, and I should return to the OEM Filter." THANKS! A little too late for that, after I'm out here dodging traffic without an OEM Filter in my glovebox.
Removing the top access cover allowed me to limp back home and remove the problem cartridge.

The 2006 intake has such a good stock tube in it that all I had to do is replace the stock air filter with the K&N lifetime air filter. Very easy to replace and with the history of K&N I TOTALLY trust that it's keeping EVERYTHING out of my engine!
