the article is a bit dated, so there's a good chance that the companys has improved their products. In general, its nice to see an independant do a study on the available filters. I believe Ill be picking up an ac delco filter next.They should be on sale at autozone sometime this month
I figure I can just take it out at the track to do runs.
Believe me, KnN has possibly gotten me for close to 2 grand these past 20 years. So its not like I wasnt pulling my weight
