All the MAF stuff aside, I've never been a fan. I've seen people with diesel trucks running that have collapsed and sucked into the intake tube. Granted our trucks don't have turbos, but that alone makes me question their quality. Plus I fear a more "open" filter would allow more particles. I'll keep my stock pleated filter.
I used to run k&n years ago until I had a before and after used oil analysis done and silicates went up about 30%.
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
The OEM ones on 3rd Gen Tacomas are better believe it or not. That KN one is going to dirty up quick and mess with your maf sensor.
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.
