Well, I was asked for my opinion. It is biased by lots of experience and hands on testing, albeit mostly my own, except for the oil comments, which I gather from a ton of stories of MAF codes due to gumming, some of which I have fixed, by filling landfills.

My point would be more valuable if one of the pleated delco elements were stretched out. It is easy to see how it has 5x the filtration area of ANY of the aftermarket elements. Then add filtration effectiveness to the menu of priorities, and there is no contrest really. The delco element will hold 10x the dirt with half the loaded restriction as any of these oiled "competitors". A pretty good study was done on this very topic.

This is just my funnybone, don't take offense please. My remarks are honest. That pathetic plastic box, with the exception of its stupid hot air design, is unmatched for its combination of freeflowing, filtration ability, reliability, and cost (free). With a new element, it has a measly 8-10 iwc pressure drop with stock flow rates, and up to 16 with highly modified (450HP) flow rates. These are nothing compared to industry standards, which average over 20 iwc for forced induction applications.

One other thing that should be mentioned. Other intakes are designed to be louder. Let's not mistake that for faster spoolup. I have yet to see anyone quantify faster spoolup.
