I notice a difference immediately after cleaning my K&N, especially if it's after an off road adventure where I'm sucking dust from my lead. I've also noticed minor improvements in MPG when it's fresh and clean. I dunno about idle though, maybe? If yours was 19K miles, then it was 14,000 miles overdue so that's probably why.
I have a K&n on my 15 taco and so far no problem had it in for a year or two but to be safe a year and a half I oil and clean it every other oil change and haven’t had a problem my taco is 4.0 L AT
2000 2.4 here. Yup, runs better. I also just hate yanking out a filter and throwing it away every few thousand miles. Never had a map problem. I clean mine every other oil change. Probably excessive, never really dirty.
I use one and I have no problems with mine. I have a 2015 Trd or. Just follow the instructions carefully on proper maintenance and I too feel the difference every time I clean it. I never had a maf issue
I replaced my factory air filter with the K&N one and noticed a much smoother idle and even slightly better throttle response.
Brought a throttle body spacer, knock off K&N filter, and 08 air intake tube. Big improvement on acceleration and gas mileage. Was getting 12mpg in heavy city stop/go…now I’m averaging between 15-16 in the city. But you do go thru gas much faster stepping on it.
the k&n filter does get dirty quite quick but as long as u dont neglect it your golden.
I didn't notice much of an increase in mileage since I did it almost immediately.
I wouldnt use the k&n though. They dont offer any real advantage and the oil a k&n uses can foul the air mass sensor.
This proves what most people have always said, K&N's don't filter for shit, also FRAMs are no good.
