Cobra CAI.
Running a Cobra CAI.
I'd like to think the filter keeps the MAF clean but it's been 5,000 miles since I last cleaned the air filter + 2 events in heavy rain.

...mixed driving with a pull or two.
@Bona, consider ditching the BOV. The sound isn't worth the potential long term issues. Something like a PRL Cobra CAI is a much smarter choice. The stock BPV will maintain a proper A/F mixture at all times. A vent to atmosphere BOV won't. Basically, every...
