Has anyone put a K&N air filter in their crosstrek? Was there any difference in performance or gas mileage? I had one in my trans am years ago.
Priceless that it's in there and it's a K&N? Why is that priceless? You took a perfectly good filter out and installed an oiled cotton filter and that's priceless?The said:We have been running a K&N now for 1k miles.
Knowing that it is in there, for us the answer is priceless.
Over-oiling your filters? MAF sesnor cleaner is not expensive.coreybarnett said:Well in my experience with K&N on my trans am, I had problems with my MAF and the engine only lasted until 165k miles. My mom's mercedes had a K&N and her MAF went out. I tend to believe that they do let in more junk than a paper filter, and you can just trash the paper filter when done. As of right now I think im going to just keep the paper filter.
