My $.02, yes the stock filter assembly is cold air, but it's restrictive, that's why I run an EVO. Do your homework on your stock set-up. Once you see all the turns and twists you'll also notice that at 6,000 rpm's your engine's basically breathing through a straw. I've posted in the past that if you followed an air molecule, it would take like five 90 degree turns before it gets to the MAF. As far as oils from the filter burning out your MAF...I run K&N's and an Outerware on everything I have. Properly serviced filters are perfectly fine, those that soak their filters in oil will reap the rewards.
With my EVO, if I look into the drivers side intake grill I can see my filter. It's a straight shot and my engine breaths easy.
Good luck on your decision.
