K&N drop in Air Filter

[Sonic Matt]

I'm very skeptical about these air filters. I dropped one in about 5k miles ago or so and it is already oil less. I did some research and from all the studies they say they actually allow more crap into your engine. Seeing how it's oil less in 5k miles I wouldn't doubt there claims. I switched out the filter back to oem and now when I rev I hear a very quiet crackling noise hope I didn't mess anything up haha.

IMO it's not a good idea to run a oiled filter on a boosted engine but I have had one on my 1.8 for 50k miles with 0 issues.

The main issue comes from when people over oil them is it messed with the maf.

I clean and reoil it every 6-8 months and it is good and has never became "oil less"

Your clicking noise is more then likely injectors.

I have the 1.8l and was pre oiled when I bought it so I never put any on. I drove it for like 5k miles and checked it today to see it had no oil on it. So I changed back to oem. No not the injectors thats a fast clicking noise the noise I heard was different but seems to have gone away not to sure.

Did it just look like there was no oil?
Was it still the dark redish color?

1.8 is a noisy motor, I mostly ignore it.

I'd have to run out to the car to check. I'll do it on my next smoke break haha. but I felt it and it didn't feel oily at all. Yeah it sure is noisy haha the ac compressor clicks a lot as well but only notice it at a stop or in a drive thru.

purge valve makes more noise than anything. louder clicking than injectors.
