I just cleaned mine at 45k. Wasn’t very dirty, but followed instructions to a tee. Just used the cleaner, let it sit for a couple hours, rinsed with water, low pressure. Then I let it dry completely (like 3 days - I put in the original filter I still had as a temp). Once dried, oiled it enough to let it soak in as directed. Made sure nothing dripped. Popped it in and good to go for another 2 years.
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.
the only advantage to the k&n is the reusability. for actual filtration, oem paper filters are better. power differences, on these cars, i dont think you will see any differences unless you are pushing over 325hp
I've been using a K&N for a few weeks. I haven't noticed any power gains, but the throttle response feels slightly quicker (this could be in my head, but who cares, I'm happy). No difference in fuel economy.
The K&N for my car was literally half as thick as the oe, and for that reason alone I swapped back. Yes it was the right one. Personally I’d rather just swap the filter than clean and re oil one that is probably doing a worse job
As good as their airfilters are... their oil filters are as shite. They leak and are downright dangerous.
