I think those other posts were replies to the OP's question, not your's. To answer yours, I would say buy whatever is cheapest for you and put it on as fast as you can! It won't matter what kind of intake you have if you blow the motor up from sucking a bunch of dirt into the intake. You probably could scrounge up a cheap stocker at a salvage yard.Well, see that's my dilemma. I have no stock air filter. And looking on eBay it looks like the stock air filter kit is in similar prices to the cold air intakes. I'm just curious if I can have one without the other. Not really looking to go faster, but if I have to shell out the money anyway, wouldn't I rather get the cold air intake than the air filter?
