A little background, my car has 3,000 miles and is pretty much stock (performance-wise) except for a greddy cat-back I installed @ 1,000 miles. The CEL started to come out (off and on) about a week after installing the blitz panel filter. Do I need to reset the ecu?

Thanks in advance. Any help you could provide would be greatly appreciated.

If that's the case you need to make sure that there's not excess oil on your filter. If your MAF goes bad, you're screwed and Subaru will not cover a faulty MAF with a oiled filter.

The blitz sus filter is steel mesh. Not sure about the panel filter though, but I didn't think it had oil on it either.
