It is chock full of deep pleats, and a sturdy frame. The way that I look at it, I *am* getting what I pay for.
I looked at a F**m air filter for my truck. It was cheaper, but it was constructed poorly, the pleats were shallow, and it looked to have about half of the filtering media. Literally.
F**m had dribbled 3 beads of glue across the face of the filter to try and hold the flimsy and wavy folds of media in place.
After I looked at that, I decided to pay whatever NAPA wanted. A nice beefy, robust filter with a sturdy frame that was chock fill of deep pleats.
Paid $30 ITD for a AFE ProDry S drop in for the Tacoma. It should last long enough to save some $. And it sounds real nice when you give it half throttle or more. The filter cleans up easy with just the brush attachment on your vacuum, or washed if really grungy. Stock filters are about $20 or so.
I always buy Oem online usually at half of dealer price. None of the aftermarket junk even comes close in term of build quality and air filtration. As for K&N and other drop in I don’t even look at it as a filter, more like grid to stop the flies..
I just purchased an AFE Pro-Dry S Air Filters for $43.95 (free shipping) for my 07 Nissan Murano from autoanything dot com. My UOA's have been showing elevated silicon and I'm hoping that this filter helps to lower those numbers.
Shoot... I just picked up a dozen (actually 13) air filters for around $80 for 4 cars via the Kragen/O'Reilly/partsamerica site. I purchased their Pentius filters which are better built than the Frams at around half the cost. The #4309 fram ($8-10) part aka A24278 purolator ($10-14) part was less than $5.50
