I couldnt wait, just installed my Injen CAI.
All i can say is wow! I didnt expect such a boost in performance. I think the Injen works/ may work better when you have the exhaust done, as im pretty sure i gained aropund 5-10kw mid range power for sure and more torque to boot. It pulls much harder from 3,000-6,500. Has changed my exhaust note, nice and meaty now, it was good before but now it sounds like i wanted. Intake sound is growly from 3-5 onwards. The little ZRE can breathe now, no more pre-pubescent Chief Wiggum asthma stylie any more.
No engine light so far, fingers crossed. I only ran the car for 20 min and no light yet. B)
I suspect the MAF may get coated with a thin film of oil from the filter, that may cause the light to come on...
Who else is going to join the Injen clan??
