You don't actually need that last one. The split air pipe passage goes straight to the ACV, which is now just a block-off plate. Putting a plate on would be for aesthetic purposes only.

That's an old version of a diagram I did, and it's wrong. I deleted it from my attachments so it's stop showing up but I guess someone else uploaded it. There is no secondary injector air bleed on S4's, but for some reason the FSM shows that line. The block-off plate you're referring to is for the sub-zero start assist injector, which is supposed to be removed at Mazda's recommendation. As long as the plate is properly sealed this will have no negative effects.

Here's the corrected version of that diagram. Hopefully this one will get posted in the future and not the old one.

Man, it is so much easier for S5's........No block off plates and no vacuum leaks

Then again, I didn't actually get rid of the air pump for my NA for obvious reasons, I just have a RB road race system installed.

Does anyone know what happened to 2751 engineering???
I purchased block off plates from them In Early December and I have not recieved it ... I emailed them multiple times and no one responded... SCAM???
