is there really a difference if i buy an aem intake and ebay brand? i already bought aem bran fuel rail and racing pulley.

 

I dont see why not go AEM. U already have some of their products.

 

Buy eBay & put on an AEM filter. If you buy the eBay do NOT use the filter it comes with. Tubing is tubing. It's the filter that matters. I have an eBay intake sitting in my living room right now but I am waiting till I buy an AEM or K&N filter to put it on.
