Thanks, robo1! My car came with the K&N (as part of a KB ram-air kit) in the trunk, so I put it on and it's been fine. Yet, there have been reports that some who couldn't get WOT MAF numbers at 255 switched from a K&N to an S&B and got 255 right away. I like the unit that has the base funneled instead of sharp like the K&N. That's gotta help flow. But like you say, they are pricey. If I didn't have a cone filter already, I'd go for it.
