I'm having a really hard time deciding on this.  I've read quite a bit, including on here, that the stock air system is actually pretty good on the Mark.  I was originally planning on trying to figure out how to set up a cold air intake before I found this site and read what I read about the stock air system.  Then, I was like, well, I'll pick up a "high performance" K&N Air Filter because I found one on eBay for pretty cheap (used) and decided not to pull the trigger on it after I read up a bit on the .org site that suggested besides the reusable factor, it's not really better.
You guys have done a ton to your cars, so I'd much rather trust experience then hearsay.
What are your opinions on this? Is the K&N really worth it over the paper filters? Or is cold air the real direction to go?
Thanks for any tips.
