Intake/Throttle Body
 

Is there any markings/stampings on an intake manifold or throttle body that distinguish as Type-r Parts. Thanx

I dont think there is a stamp. ITR TB is the biggest amongst all the B-series TB. Same as the intake manifold. The runners and the plenum are bigger than the B16.

Remember that B16 and ITR intake manifolds are interchangeable. LS is by itself. GSR is by itself.

All B-series ITB's are interchangeable. I cant remember their sizes tho. ITR is the biggest.

Thanx, I'm just trying to figure out what TB I have. I just put in a 2nd Gen B16 but the MAP sensor is not mounted to the TB. Also it looks like I have a first Gen fuel rail.
