First off I would like to say thanks for all the great insight, im pretty new to the site and to Mazda's,(previously owned 2 Honda's). Honda's have so much more aftermarket support searching for performance goodies is a bit more involved. Ive been doing some research about which intake to get and there only seems to be 2 choices from searching previous posts. AEM or Injen and neither seems to have gained any more power. For those that have the Injen is it worth the 250 or so bones for the 1hp at the wheel gained I have seen in the previous posts, im quite skeptical , but in real world conditions do you see a noticable improvement? Any insight would be great!
