Dust/grit/debris certainly enter in direct proportion to increased flow. And in proportion to filter neglect, esp of HiFlow filter maintenance. Oil dirties faster
Since MoPar and ORECA and most race teams use K+N, and K+N has a product libility policy and guarantee on the product w/ MoPar and retail users, I vote K+N.
I rotate 2 sets of K+Ns and keep 2nd set cleaned and oiled when I get around to it. Lets the oil tack-up. Change em every other oil change. I dispose of em after 2nd use. Cheap Insurance.
No fit problems, ever. Tight fit is good...loose fit is bad.
I have also read that there are "filter sprays" for FURNACE FILTERS that are tacky, but breathe. Meant to attract and trap particles much better than filter media alone. Would likley work on air filter elements!
The paper-foams are very restrictive. K+Ns gave my 93 a marked throttle-response feel, as will any Gen-1. My GTS had a noticable decibel sound from the NACA, but no detectible throttle bonus.
When checking w/ S+B a few months ago, during the initial curiosity, was told they dont even offer a filter designated/rated for the Viper or the 8.0L Dodge Ram....just a filter that may coincidently fit the airbox dimensionally. Dunno?? Was it rigid enuf to handle the draw of the big V-10? S+B did not know, and could not help.
I cannot imagine they could do any harm if they fit tight, you maintain em, and frequently change oil. As cheap as they are, we should all consider them disposable.
