OMG MY K&N FILTER!!!
Doesn't feel/seem any different, but i wasn't expecting it to.
Anyway, the point of this thread is to see if anyone else has noticed some small performance gains (if any) or any gains in fuel economy. What's your thoughts on it ? And I paid $50 after tax @ autozone for it. |

congrats on your purchase. keep it clean, a clean filter is a must!
oh and don't waste money on the k&n cleaning kit. use simple-green to wash the filter and oil with a similar oil to the K&N kit

i'd be curious also to hear what type of oil people use instead? i've had k&n's on my past 2 vehicles and liked them, but hated paying what they charge for their 'recharge' kit. i haven't bought one for my yaris yet because i know you have to keep them clean and oiled to work(and avoid damage to your engine), but i just don't want to keep paying for that overpriced cleaning kit!

is a good substitute. any oil recommended for filter oiling, whether foam or fabric, will work. regular motor oil does not have any "stickiness" to it and will not work. do not over-oil your filter! edit: also just read that bar and chain oil (for chainsaws) works if used in small quantities (not recommended for cold-weather applications)

I can't think of a bigger waste of money than a K&N filter for a yaris. It has absolutely zero benefits and it's filtering capability is much, much worse than a paper element so you end up with a dirtier motor/throttle.

Yessir, but don't tell the Yaris fanatics that, how else would K&N make so much money?

i've already noticed a tad bit better gas economy comparing results with my SG2, and considering it is lifetime guaranteed', by the time i change my filter twice with the gas ive saved after all those miles it will have paid for itself and more.

When i put the K&N drop in, the yaris felt slightly better/quicker, but not a whole lot. Also seemed smoother on the freeway, its been so long now I can hardly remember though.
As for filtering efficiency, I have a few questions. I checked out a few websites, but can't find any definitive answers. Does anyone have a link to lab results, or measurements of dust and dirt that passed through different types of filters on the same engine? K&N says they filter 99% as much as paper, but i can't imagine 1% extra dust over 200k miles being good. I'd also be interested in seeing some numbers on filtration for cold air intakes, as that might be my next move. But a lot of people seem to think I'd be best off to just put the stock paper back in.. (I've read every viewpoint based on hearsay pertaining to this - that's not what I'm looking for. I need concrete test results of different types of filters(and the crazy guy taking pictures of filters after 500 miles doesn't count :P ) |

K&n filtration/cfm flow is the highest of any aftermarket filter(many winning baja/off-road/track vehicals used k&n filters) . I'm running a k&n drop-in but I hacked my stock air box and flipped it upside down , so the filter is facing up . I also have a vented hood, so its getting air from outside the engine bay , so in my application its works just as good as any sri for 30 bucks . I could see how you dont notice any gains with the filter in stock configuration .

And if I had one I'd be worried about either using too much oil or not enough. I've been told that they can't harm your MAF but I know that's not always so. A Toyota Avalon owner had a brand new K&N dropin that must have been over-oiled enough that it set a code and couldn't get much over 50% calculated engine load at WOT, until I cleaned the MAF and switched to a WIX filter...code didn't come back and saw well over 80% calculated engine load at WOT on my scanner's datastream. Maybe someday GreenFilter will come out with a P/N for our Yaris. Similar to a K&N, just a little different approach.

Dogging on K&N is a popular thing to do because they're so big, but here in Ohio we have these things called race tracks and guess what filters they use on the cars? K&N's are tried and tested. I don't run one, but I wouldn't hesitate to.
Oh, and they stand up extremely well to wear and tear. My friend has one that he has been running for 150,000 miles and it looks to be in better shape than my generic, which I've had about 25% as long. |
