What about building one from Napa parts. I think I posted up the pics and details in the "Knowing your IQ" sticky in the IQ section. EW
Found 'em.
You can see the element is bigger and won't fit in the stock location. wasn't a problem in the boosted IQ's with no air box. Haven't looked into the Pro yet, but there must be some place you can put it using extra hose. The Napa filter has more surface area and a click or two finer micron count if I remember right. About 1/3 the $$ too.
