I bought the truck with a k&n and throttle body spacer installed, with the stock stuff in a box. I'd assume the filter needs oil, and everything I read points to spacers just being along for the ride. I really doubt that I'm interested in oiling a filter for my truck. I've just installed headers and the pipes and tune are on the way so I'm not looking to do anything that involves some larger bills for a bit. Would you
1. Leave it alone and suck up oiling the filter. (I'm not a huge fan of oiling, seems to me that if it relies on oil, it's not meant to catch what it should.)
2. Go back stock, it's not that big of a gain anyway.
3.? Throw on a new filter head? Are they all oiled?
Thoughts?

put the stock back on is what id do. If you don't wanna mess with oil. theres a free DIY you can do with the stock filter setup that is said to give you some decent gainzzzzzzzz....maybe look up ******* mods or something like that.

Or look at R2C filters under their conical race filters and see if they have a replacement (they should) that will fit that 3'' K&N intake pipe. R2C are dry filters and only need compressed air to clean them.

Check out this page, it has the filter sizes at the bottom. And they are cheaper than K&N.

Cleaning and oiling a K&N filter isn't hard/expensive. They sell kits at any auto parts store for around $10.

Spray on the cleaner, rinse off with hose, let dry completely, spray on oil, put back on truck.

Thanks for pointing me towards that mod. After reading through that I got worried I'd open another can of worms! Checking out the "how to" on oiling a k&n I see they have some serious mileage between cleaning and oil, up to 100,00 miles in optimum conditions?!? Maybe I'll consider giving this filter a shot, I don't know.

Lots of reading to do on that r2c site. Has anyone read it thoroughly? Are they referring to the material all other after markets are made of being suboptimal? I only glanced at it quick so far

I've run my R2c for 2 years now, no issues. Even did an oil analysis test a few months back and the filter does it job keeping contaminants out of the engine.

AEM filters are dry units... I use one in my Nismo filter box. They will fit most any of the other filter boxes. Just get the right opening diameter and length. No oil here... just clean air crossing the MAF sensor. :thumbsup:

That's another thing that concerned me... Getting oil on the MAF. Not sure how frequently that's an issue though. Thinking I'll run this k&n for a bit until the cash bleed has slowed and then look at switching the tip to a different dry filter.

As long as you let it dry and don't over oil it (dripping off the filter) you're fine. I run a dry filter in mine, but just put a drop-in K&N in my wife's Maxima and haven't ever had an issue over-oiling one of those before.

I'm just throwing this out there... But you "just" put one in and "haven't ever" had an issue? Hahaha. Which one? (Just bugging ya)

I used to run one before I got my MXP, so 6-ish years on it. Had one in my wife's Mazda for 7 years before her current car. I've had to clean and oil them a few times.

I ran a K&N CAI on my 08 frontier an had to change a maf because of my own fault. I never ever had oil dripping off my K&N filter but clearly there was too much
