Great idea but when i did that i found out when i failed my smog check, since i live in Cali. you need a carb sticker crap and so since i had my k&N filter i just bought a AEM pipe and then i passed, but nothing against the ebay intakes pipe it was good but as far as the filter ....:thinking: yeah i didnt even think twice about that filter and so i bought a K&N great.
