Ditch the friggin K&N P.O.S!!! I did the upgrade to the K&N and I am totally pissed off with the product...Here is what I have done, I added the Dynomax UltrFlo welded muffler and exhaust system to the truck and then added the Hedman headers, this was a good decision. I have had zero problems with the install and the truck sounds awsome, on these two upgrades you will not be dissappointed. Prior to adding the K&N filter and tube assembly I had my rig go in for a top to bottom check and fluid replacement. I syn'd (Synthetic) all my fluids with the best stuff I could get, I flushed my engine, brake lines, transfer case, rear end and transmission. All in all I spent around $1,200.00 on this maintenance run.

Now for the K&N intake, I too thought that this mod would help in the overall performance of the truck, but when I looked at it closer I noticed that you gain the most HP at around 4000+ RPM's...when the F***K do you drive the rig that hard to rev it at 4000+ rpms. in order to notice a 12hp gain??? Okay, enough said about that...now for the important stuff, I did install the filter on my rig, at first I thought neat, you can really hear the airflow through this thing! But after about a week I was driving home and heard a very loud rapping sound from the engine compartment, I pulled over to find that the plastic friggen tube had come loose and banged against the fan blades, the fan blades took a 1"X2" chunk out of the corner of the tube. The draw back was, where the F***K did this chunk go to?? I had no other choice but to quickly tuck tape the corner and afix the tube back on the intake, (Another reason why you should carry some tools in your rig at all times). When i got home I called K&N and told them that i would need to replace the tube and if they could send me a replacement, (Don't misunderstand me here, I realized I may have not tightened the screws enough on the "O"ring and it was probably my fault the thing came off, I was not blaming them fo this, all I wanted to do was buy a replacement) they said that the tube is not sold as a seperate item! HUH!? WHAT?! I thought she (Sherry) was confused so I explained once again what I needed, again she replied that they come as a set....HS!!! I don't need the entire item all I want is the tube...sorry she said and that there was really nothing she could do.

I then called TRUE FLOW and they have a filter #10220 which will fit in my original air box (thank christ I kept this) and needeless to say I ordered it right away. When I finally got my TRUE FLOW filter I pulled off the K&N and was amazed to find alot of fine particulate dust on the inside of the plastic K&N tube and intake manifold, it took me almost an hour to fully clean out my intake all the while making sure that nothing gets scratched or damaged. I also found fine peices of plastic around the head of the intake, needless to say this was from the fan blades when they chunked out the intake tube. I had to spray a cleaner directly into the intake in order for it to flush out all the crap and fine dust that was in there. Granted the plastic breaking was a huge piss off, but after I saw how poorly this filter actually worked I was dead set to warn others about it's claims before they suffered a serious engine problem. To top it all off I went back to my mechanic and had them drain the Synthetic oil out of the rig,(remember, I just had this replaced a few weeks ago) replace the filter and let me know what it looked like. My mechanic phoned me back a short while later and asked if I had gone through somewhere extremely dusty? I said no, and he replied that my oil looked like it had alot of crap in it and was wondering if it had anything to do with the K&N filter letting too much particulate through, if so, he recommended I change back to the original filter from GM ASAP! or get the TRUE FLOW system right away. So Beware, the friggin thing does not work as well as they claim it does! This is based on my own personal experience with the K&N Filter, judge for yourself, but beware.
