Dealer told me I have an aftermarket spacer. News to me. I dont know much about them so i didnt know if anyone could identify this. I did some research, looks like a motordyne .5"? not sure if theyre similar in appearance.

 

Yes, that is a plenum spacer.

 

Looks like skunk2. Just leave it on. It aint hurtin anything

 

sweet mod, keep it and dont worry to much about it.

 

It's a spacer.. be happy your car came with it. If I sold my car, I would take my Motordyne spacer off and sell the spacer on E-bay, because they cost a good $200+.... you basically got yours for free when you bought your car.

 

what did the dealership say?

 

Its going to be hard to identify the spacer since they are all practically the same in appearance.
