for a 5th gen.. somepeople say its no prob to install but then again i see stories of sensors misplacement (?) and check engine problems ... for anyone thats installed it on a 5h gen.. do you have to do any modifications to it or your engine bay (like cutting or makeshift solution type things) ??

First let me state that these were my own observations/problems and may not reflect everybody elses situation.

I installed a JWT popcharger early last year. It was great except for the annoying whistle at part throttle. It wasn't until the summer months that I started having problems. On cold starts it would sometimes lunge under full throttle, as if there were a severe dip in the power curveat roughly 4500 rpm. After the first few times it happened, I suppose the ECU "learned" and compensated but it never totally disappeared. The other problem I experienced was knocking under light load on hot days from a standstill. There was two reasons for this, the first is obvious, hot engine bay air getting sucked in rather than cooler air while moving. The other reason is because the Air Intake Temp (AIT) sensor can't be mounted in a good location with either the JWT or Stillen intakes. Just the nature of the beast. The FSM states that the AIT sensor is there to adjust timing for temp changes and should be in the full airsteam of the intake. This is not the same as the Mass Air Flow sensor (MAF) which adjusts the fuel/air ratio. Overall I didn't see either as a huge problem until one day last fall my MIL light came on. Resetting the ECU (by disconnecting battery) didn't take care of the problem for long so I decided to go back to stock intake with K&N drop-in. Haven't had a problem since and it's so much quieter.

I hope this helps.
