it's actually quite simple. I've had K&N's on 2 vehicles for over 20k miles before and never sucked oil in once. When you first install it out of the box, let it sit for a few hours or even overnight to let the atmospheric air get at it and evaporate the extra oil caused by letting it sit in a sealed plastic bag. Also, when you clean and re-oil, don't try to emulate how it came out of the box, oil it enough to get a nice coat over the element but not in excess. Also, make sure your filter is dry after water washing it (reverse direction obviously) before oiling, as a wet filter will not allow the oil to cure to the element, thus allowing it to be sucked in through the intake.

I would get a Toyota TRD drop in filters.....it puts K&N air filters to shame and fits the box snug and tight....I personally like FRAM air filters, not only do they have a superior air flow but do a great job at filteration too. All my prior UOA's prove this and I have discovered that leaving it in for 30,000 miles even though they say replace every 12,000 miles was optimal for cars driven in normal environments(i.e. not desert enviornment or heavy towing etc...)
my FRAM air filter is coming up to its 12,000 miles
so i should keep it in there for another 18,000 miles?
wont it rob gas mileage?

I use a Wix filter for the most part, or OEM if I can get it without a second mortgage.
I have a older 90's video somewhere showing Amsoil vs K&N on a flow bench, the dirt in the 1 micron range, Amsoil stopped 99% of it, K&N passed nearly ALL of it.... It was all on the flow bench, no trickery.

I have run K&N Drop-in's in all of the cars I have ever owned. I do it simply to save money. I buy one air filter, and never have to buy another one as long as i own the car. Just wash, let it dry and re-oil. For $50 (plus the cost of the oil) I never have to buy another filter. Works for me.
