Good luck.

boxster didn't get variocam+ (continuous variocam) until 2007 (996 got variocam+ in 2002). according to pet, a helmholz chamber was only used on base 986 boxsters; the higher performance 's' models didn't get them *** i stand corrected - my 2000 S did have a small one also!! *** the 987 does have one however it is now located before the maf on the airbox - it is the thing you have to cut off to fit the airbox in the 986. my understanding is that it only has benefits at lower rpm as it contributes to intake pulse tuning; if you can keep it fine, otherwise it is one of the sacrifices you make when building a higher airflow intake.
