Chinese copypasta crap. Procomp/pro products etc... are all of that ilk.
Get an explorer intake from a JY or one that is already pulled from ebay or CL or wherever. If its going on stock heads or GT40 heads bolt it on as is, it flows 200cfm stock. If you are going aftermarket heads send the lower out to tmoss to get ported out to 250cfm. The upper already flows 250cfm so no issue there. The GT40/Explorer/Cobra intakes produce the best low end of any of the 302 intakes and will keep up with even 170cc TW heads if you port the lower. And they are CHEAP.
