Looking for first hand experience.

Does the OEM gasket 99711031990

still get used when bolting throttle body onto the IPD plenum? I noticed there is an oring in place when the plenum is shown in pics. Does that oring complement the factory part or replace it all together?

 

I hvrh installed mine. Check my build thread.

O ring on IPD Plenum is there.

​​​​​​There's another option niw by do88.se

​​​​​​If yiu didn't purchase IPD yet

 

Did you just use the o-ring and no gasket.....or did you use o-ring + oem gasket?

 

Just an o-ring.

 

Thanks guys....IPD returned email. Just the o-ring is correct.
