K&N Filters

[1stToyota]

My 3% might be high? The % of DYIs can't be that much by comparision, and most probably don't get a K&N, probably get a Fram, Wix, etc...

Nah, I was just saying that people should ignore those percentages, because most people have someone else make the decision for them.

Wix is kind of on the pricey side aren't they? I wouldn't know as they're not even sold at the el cheapo stores by me. I actually prefer Fram for oil filters because of the grip anyway even though I'm told Wix is the best there :)

I do it myself because I want it done right, but I don't want it to be an expensive pain in the ass either.

I ran K&N on my TJ for years and I never had any troubles with it, though I rarely cleaned the intake/throttle body. The worst build up of oil was honestly from the PCV. I actually had to get a pick tool to clean that out (not a valve on the TJ).

Funny story, it's was the same with the Harley too actually. It used to have one of those doofy hyperchargers on it. The rubber fittings on the PCV just fit too loose causing oil to spit out (before I replaced the top end gaskets and rotated the rings correctly).

I think I really want to put one of those PCV filters on the Yaris as described in the DIY section here before I start oiling my filters with engine oil:) I wonder if that would give the dealer an excuse to void the warranty.

If the people want it bad enough, no matter what it is, they'll get it. Not a big deal either with getting it installed by your local mechanic, or whoever does the service, and cleaning it shouldn't be an issue either; in most cases cleaning will be a couple of years down the road.

And the PCV issue really shouldn't be a big concern...most vents are at the bottom of the airbox, below the air filter, so you'd have to discard the air filter completely, or damage the gasket bad enough to allow it to effect the MAF...or the PCV vents downstream of the MAF near the throttle body.
