I have one, ready to go on. It's not as simple as just pulling out the combivalve and bolting on the blanking plate though. That valve deals with more than just the SAI.. then there are the open circuit errors to deal with, and the incorrect flow faults that need mapping out, various re-routing of vac lines etc. I'll do a more in-depth writeup (and hopefully be able to offer a complete plug/play kit) when I've done it but here is a bit of a writeup done by a vortexer
