Looks like it will work. Ecs tuning sells em for 10 bucks each. I'll be using this on my m52, thanks!

does it need a weld?

The exhaust manifold holes are different spacing than the valve for the airpump.

you can use 1x of part # 11121438086 to block off the air pump valve.

the 2 pipes with flanges that go over the exhaust manifold will need to be re-used with new gaskets; I did this for my car.

ok i think i get it you remove the air pump thing and use that block off but leave the pipes connected?

I used part number 11727511542. Still had the holes welded closed. Just thought this looked cleaner. Had to grind the center i little bit to fit.

Out of curiosity, is there a reason to remove the SAP other than converting to OBDI? I have an E36 so it belongs in my car, but I was wondering if it increases power or something?

From what i understand its just an emissions component and can be deleted. it has something to do with the idle when the car is warming up or something liek that. i had my DME flashed to remove it so i dont need it.

European obd2 cars don't have it.

Secondary air pump is something designed for California emissions bs.

No power difference with or with out it; similar for the crankcase vacuum cyclone.

Obd2 is much smarter brains than obd1;

I removed the air pump system and left the steel pipes in place to cover the exhaust holes

for you guys that have deleted the sap on an obd2 car, what did you do about the CEL?

[Mistawall]

We'll I had it deleted when my DME was tuned

11121438086 plate is not intended by BMW to fit that placement; that's why you had to massage it to fit - Good idea on the welding and using this as a vanity cover.

11121438086 fits any place there is an AIR VALVE; bmw made the flanges and gaskets all specific sizes on purpose. This is a total PITA on a V12 with 1 air pimp, 2 Valves and 4 flanges on the headers.

Bimmerworld sells these plates too for less than IE.

If you use these, do you still also have to weld the slots on the flange to close the gap between the flange and the head?
