I am changing AOS on my 2003 Boxster-S, I also want to change the intake distributor sleeve. The sleeve on right side has a nipple where a check valve is inserted. The sleeve on left of the TEE does not have nipple.
The part number printed on both of the sleeve is same 996-110-685-01. The diagram that I can find on Porsche dealer parts diagram has same part number for both the side.
Any idea on what the correct part numbers are for left and right sleeve (one with nipple and one without nipple). Please see attach picture
