When fitting the 4x4 plenum to a 2wd will the 2wd cupped washer damper and bracket still fit?

 

What cupped washer and damper?

 

This is what the 2wd has as a inlet support but can’t find any details of what the 4x4 uses?

 

Ahh right, the 4x4 has that as well. I bolts to the top of the engine mount which is different from a 2wd. The 4x4 mount has the two mount holes offset and looks different to the one in the drawing. You'll probably just be able to use your original 2wd mount. I've an RS 500 inlet in my 4x4 and I use the 4x4 mount.

 

So I’m presuming that the brackets are the only difference then because the 4x4 engine mount sits in a different position, but the throttle body mating face of all the plenum elbows including the damper position all sit at the same orientation/position once bolted to the head, if that makes sense!

Im not being lazy by asking this as I would just try it on the car but the car is elsewhere at the moment.

 

That must be why they are different, to take the engine mount location into consideration.
