Hey everyone, I have a rather strange problem. I have an 87 325is which comes with the “L” shaped IACV. The previous owner for some reason put the “T” shaped valve on instead, as well as changing the intake boot to match. Well the boot was cracking so I ordered a new one. However, the new boot I purchased doesn’t fit the car (the end that goes on the TB is too large). I’m stumped to why this doesn’t fit because the genuine boot I had before is the same part number with the extra hole for the check valve on automatic trans cars. Are there two different boots for these cars or is the aftermarket brand I bought (meyle) bad?

There are plenty more experienced people here than I but I’m pretty sure the pre ‘88 engines cant use a post ‘88 ICV, boot, and valve cover breather tube, the engine wire harness just doesn’t work The same.

Thanks for the replies everyone. My intake manifold for sure looks like the one off of an “i” car. I cross checked the part number off of the old intake boot and it comes back to a 320i..... That car was never sold in the states. I’m not sure about the throttle body at this point, but I can take some measurements tomorrow. I was redoing all of my intake hoses and everything fits that I bought off of ECS tuning (all gaskets and hoses on intake side of the engine). My car also has the pulse sensor for the #6 spark plug wire which all the forums and websites say my car shouldn’t have? Super weird stuff. The part number on the intake boot is 13711726204.
