Air filter poll
 

Just curious of what the break down is here.

I have a K & N but my CEL light came on and it pointed to a dirty MAF(probably caused by my K & N). Cleaned and no problem 30+ miles later. If it comes on again with same codes then new MAF and new Mahle Air Filter.

I am running the Evo intake system. Great improvement.. has a dry cone type filter I believe. I did have the CEL come on this month... although it has been in my car for
6 months. MAF code 1128... I believe I have a fuel pressure issue or dirty MAF. I will keep everyone posted.
