IC Hard Pipe Replacement Kit Available Soon

Could the MPG gain be that the engine is running less rich and less restricted with the intake and exhaust mods?

I'm sure there's less restriction now and the entire system is running far more efficiently...I also know my AFR's didn't change at all so I can't say that its running any richer or leaner...The ECU continues to do a great job readjusting itself nicely to all the mods...But I didn't expect by replacing all the IC flex hose and plastic stock charge pipe with hard pipe to see any further improvement to mpg's...Originally, after the install of a 2.5" Catback and CAI a while back I did see a 2-3mpg improvement ....Now I'm averaging ~28mpg just around town now and my AFR's continue to remain the same....

FYI...

Just some install tips that may help...

Install is much easier if you first remove the left flex hose first and then this will allow you more room to remove the bracket holding the right plastic IC outlet pipe! Once you remove "all" the hose clamps you then simply slide the right IC hose (which is still attached to the plastic IC pipe) down and out the bottom...Install of IC hardpipes start with right side and then finish up left hard pipe...

Its interesting how more efficient the turbo spools now with all of the flex hose gone. Before the install I noticed at WOT the boost gauge would read just under 12 pounds of boost. Now with the hard pipes at WOT it reads just under 14.

Yes it definetly noticeable...more than I thought it would be...And that seems to agree with Injen's reported gain of (+8hp) (with the replacement of only one flex hose and charge pipe) which is roughly equivalent to 1-2psi boost pressure increase...I also found after my install I had to "dial" my manual boost controller back down 1-2psi to +16psi....

Two questions...
Do you need to get underneath the car if you do it this way?
I only get a boost reading from y gauge...where did you tap it to get vacuum/boost

You definitely need to get under the car to do this. I tapped into the line coming off the DV.

hey ARF...

You will need to raise the front end up a bit to get under to loosen up the lower IC outlet hose clamp to remove and replace...




Boost / Vacuum source:

Is 14463pa being replaced only on that side?
Thanks... I will move where I am tapping the boost. I was getting it before the solenoid

Yes...from "lower" IC outlet to charge pipe those two pieces are replaced with one solid 2.5" hard pipe
