4. more intake capacity(bigger filter and piping)
5. more pressurized-bigger intake, then pipe get's smaller at the maf...maf reads more pressure??...the bigger again, then smaller right at the throttle body...map reads more pressure??best way i can explain...i'm tired
6. bolt in a better place than the aem...thus allowing it clearance from metal wall, but then u have to cut the splash guard...aem i cut my splash guard and it still hit the wall...so then i put foam in between it and the wall to stop the vibration noises.
7. the butt dyno doesn't lie.....in this case it's not just the butt dyno, it's the back dyno also..i can actually feeeeel the car pull now...
8. IT'S NOT JUST A PIPE...if it was i'd have made my own and so would every body else...don't think honda would do all that to their intake system either if just a pipe could have done the job...FLOW/VELOCITY etc etc: it can do a lot of different things...like cause hesitation in one pipe and none in another...so it's not just a pipe....ever seen the aem v2(can't be used on Si)...is uses sound waves and air flow to create power(i think)....it's not just a pipe.

What he said. There is a lot of Research that goes into the development of these "Metal Pipes". The Injen Cai is the only one that offers a Pressurized design which works a lot better with the Si's MAF. I just received mine yesterday and it is a very well made product. I chose the black powdercoated version since you really can't see it from the top anyhow and I read somewhere that the powdercoated pipe will stay a bit cooler.
Anyway, I will try and install it this weekend. I just hate to cut into the fenderwell but if it has to be it has to be
Can't wait to feel the difference.
