Installed the RBC intake manifold and Injen Intake today, Results were dissapointing. Best of stock dyno runs 91 kw atw, best of after installation runs 99.2 kw atw. Power output until 6500 rpm is pretty much identical and then from there on till the rev limiter there is 8 kw atw increase. Also 600 idle RPM now, with the car sounding like its about to stall every 10 seconds when stationary and all i can do now is get it used to it until i do an engine swap. $1200 down the drain and i dont recomend it to anyone. Any ideas on what engine i should drop in ? currently considering 2007+ Cl9, FN2, FD2R engines.
