ALL I really know is to stay away from anything that says FRAM on it...SO my vote will be 100% K&N...IF i had to chose from those two...
Stock paper filter. Any gains you might see would be measured in a fraction of a HP, and any extra flow that you might actually get from a high-flow intake filter is just allowing more dirt & abrasive crap into your airstream. And of course, with the K&N, if you're not careful about how much oil you put on it, you can muck up the MAF.
If you really want to, I'd say K&N. I'm not a fan of ANYTHING Fram. I laughed when they started getting into lubricants now, too. Anyway. Stick with what's proven. K&N, if only for the reusable-ness.
Supposedly the Air Hog's are the exact same patent and design as the K&N's. That being said... I'd go with the K&N. The price difference is small and like jackbauer said...trusted brand. However, I also agree with Vector about the stock paper filter really being the best choice.
aight kool. thanx for the info guys. because i am going to remove my spt intake and boost controller and sell it
K&N filter is a pain to get in and out of my 07 WRX! Just worked on it today. I don't like the thicker rubber making it a B*tch to put in and take out. You practically have to take the entire box out to swap it.
well too late i've already got a HOG. Thing is now I can't find my bolts to sstrap my stock box in so Imma go to Subaru Dealership and see if they got them
