to K&N or to not

[Cobrajet]

I have a K&N flat filter sitting in a box. Took it out after having multiple CELs for MAF codes. Haven't had a code since.

I have a K&N cone filter, with a K&N oiled foam pre filter over it stuffed into my modified stock airbox.
Plenny air to feed the hungry S-C.

Yes I do throw codes now & again because filter oil fouls the MAF, but I don't find cleaning it 1-2 times a yr, with CRC MAF cleaner to be THAT big a chore...

I've got a K&N 63 intake kit for my h3. Best $300 i've put into it so far. No problems at all with it. Big difference in acceleration, especially at higher rpms.
