So far, it seems that truck is much more responsive and lively. It appears that it is breathing easier. Not sure if it is directly related the the k & n or the charcoal screen delete, but definetely the combanation seems to have improved the intake some. I still assume a CAI system would make my truck more responsive with a slight hp gain and at least another mpg +. I will try to observe over the next few weeks and let you know if I experience any mpg increase with current mod. Jason-I did the modification on Friday.

I still plan on doing at cold air intake, but will try to hold off and felt this is a descent compromise for now ( and much easier to explain to the wife! ). By the way after my last visit to the dealership with regards to the gas pedal recall issue the shop foreman said that he had no problem with the "charcoal filter removal" . He said it was there to help control emissions, but that it would not; a) void warranty b) cause a failed vehicle emission inspection c) cause any damage to the engine. I plan on doing both, k&n & charcoal delete tomorrow. Thanks once again Jason.

The cleaning procedure (every 25-50k miles) is to wash and then re-oil the filter. It's ready to go out of the box, and it's definitely a great buy. Ralph – It’s pre-oiled at the factory.

I think I am going to go this route first due to cost factor. I am a little confused though by the comments of "pre-oiling" this filter before inserting it. I thought K&N's performance air-filter (part no.33-2387) came ready to install. Is it ready to install or is there any prep work required? Jason,

I haven't noticed that filter before - perhaps it's exclusive to the 4.7. The only functions I can possibly think of is that it either somehow protects the MAF sensor (which I sincerely doubt) or it's designed to absorb moisture (also doubt that as well). I can't think of any reason for it's existence - if the air filter is doing it's job, there's no purpose in a second filter in the tube. I say remove it.

The filter I’m referring to is down stream in the air flow path, meaning the intake air has already been filtered by the air filter so I don’t know what your comment of “to block any really big “junk” from getting into the paper filter” means. Any big “junk” is caught by the regular paper (or K&N) air filter. All I can think of is that this second filter, filters the air again after passing through the “main” air filter but since it’s non-replaceable, it must not ever clog up with dirt so I still don’t understand it’s function. It would make sense that if this second filter was removed, air flow would increase as would the intake noise. Am I correct or am I missing someting?.

First, it's meant to block any really big "junk" from getting into the paper filter. Second, it's a noise reducer. Removing this filter is an easy way to boost your stock intake's power, but unless you also replace the stock paper air filter with something more durable, it's a bad idea to remove it. Does that make sense (I don't think I explained it very well)? Carl – That filter has two purposes. First, it’s meant to block any really big “junk” from getting into the paper filter.
