Anyone know if there are differences between the GEMS and Bosch Throttle Body Heater Plates?

Maybe I'm looking in the wrong place, but it seems my existing plate which I assume sits directly under the intake manifold is bigger than the replacement plate. RAVE refers to my existing part as the Water Jacket (GEMS) and has an image exactly like my existing setup. I can't find an equivalent description for the Bosch years.

All the Rover parts places indicate that the replacement plate fits '95 to '02, yet the replacement plate is far smaller with coolant pipes at an angle. Am I looking at the right thing?

the part you have is bosch specific. I dont think that the GEMS engine has the same part. it is only listed for D2, not D1's.

It wont work, angle of pipe stubs wont allow for easy pipe connections, the proper part is available as so to is the gasket
If you are replacing cos one of the stell pressed in pipes has wiggled loose I repair them by tapping in a brass piece, better than original and will out last the rangie

I'm getting an occasional leak from that throttle body area, and I suspect it may just be one of the hoses. I have a replacement for that. But since I was going to be in there I was going to take care of the heater plate as well since I guess they have a reputation for leaking. The fittings are wiggling, but maybe there's a small leak there, as well. I'll check it out. Thanks for the tip!

It's a carbon-fiber intake elbow that came stock on the 220 Callaway edition vehicles sold in the US.
