Parts #4 and #5 in Andy's diagram are reasonably easy to access with the airbox removed. A good DIY writeup is here: https://rennlist.com/forums/993-foru...eck-valve.html

My only add to Bruce's excellent writeup is that I find it easier to remove the airbox and MAF housing as one unit, by loosening the hose clamp on the opposite end of the MAF housing from the airbox. Once out, you can separate the airbox from the MAF housing using the twist lock.

I'm not sure I've ever seen a writeup on R&R of #14, but others may have experience.

Is # 14, the changeover valve?
...and # 4, is the air injection valve?

Pelican Parts offers an instructional cd on this SAI valve change along with that special crowfoot tool. Made it easy.
Video is part # 94-98-993-SAI-DVD.
Crowfoot kit is part# YCG-SAI-KIT

Thank you! My apologies for getting lazy...

I can't vouch for the DVD, but the Yellow Cap Garage kit is a good buy. Both the modified crows foot and the compressed air fitting to replace the check valve were well made and did their jobs nicely.

No worries. It's not like you have a copy of the catalog PDF on every device you own just for quick reference. I mean, who would do that, right?
