Is it really nescesary to pay upwards of $100 or a K&N or AEM system? I see a filter its just like a K&N but only $20 shipped brand new on eBay. The reason I ask is because I just put my ATV K&N on my car and it was the perfect fit lol But the K&N for even my ATV cost $40 or so just for the filter and if the $20 one actually made for the car new intake tube and all is equal or better why pay $40 for a ATV K&N to fit on my car.
