I know im going to get eat'in up for this but there was actually no specific car cover for the Type R. all they did was make one that fit the Integra. Given it fits on the R, it was not specifically made for it. But the expierence that I have had with it has kind of snug fit in the back but nothing to complain about.
Have you tried your local Acura dealer. Most of they accesories for the Type R's are still availble
