Did the FRA mod last weekend and have been loving the SOTP difference it makes (I think that it made the aftermarket lid and cat-back more effective).
Today when I did my 9,000 mi. oil change I decided I would take a look at the filter just for the hell of it. OMG was the thing filthy in that strip along the back of the filter. I mean it was black! This is both good and bad. I think the filter flowed more air in the past 500 miles than it did in the first 8,500 but it's really dirtying the filter fast!
How often do you guys with the FRA change your filter or, if you have a Holley PowerShot or K&N how often do you clean it?
