Thanks for all the info guys.
So no CELs with you COBB guys? that is the #1 factor for me, I don't wanna any rigged up crap throwing CELs every other day. If it does not throw any CELs, then after my research as well COBB is clearly the winner.
Same or more HP, significantly less cost, easier to install, easier to clean filter, and easier to swap back to stock airbox if u have to take your car in for warranty work.
Its hard to believe that the COBB and CP-E intakes don't throw any codes, when the actual MazdaSpeed CAI product does.....seems it would be engineered to be least likely to throw codes =(
Side note, where did you buy your COBB intake?
