all you that run apexi power, how big is the intake inlet? there's this vendor on ebay that says it's 2.5 inches, that's small... the one on apexi's site LOOKS different and bigger, which is it???

 

mine is made out of banana peels, extra low restriction slippery pipe

 

HKS RS intake is on my car. I never had any problems with it. People say it leans the car out. I had mine on my car for 8-9 months with no problems before I got a DynoFlash. I have a buddy that put one on his car right after I did and is still running fine with no problems.

I picked up about 12 whp with just my RS intkae on a AWD Mustang dyno.

 

So the HKS RS is overall best Intake with best sound and most most performace out of it??


What about this one?? Any opinions on the ARC?

 

Did you reflash after the installation of the RS intake? My car got reflashed but still uses the stock intake. I'm afraid that if install the RS intake after the reflash, the mappings can be screwed.
