Anyone know the exact dimensions of the Oil cap on the RCF? I wanted to buy a aftermarket oil cap there is a few different options and colors out there from $7-15 on average so they're a really cheap mod I just didn't want to guess wrong most say they fit the scion but most toyota/Lexus models, I found the specs of a couple listed as for sell for the RCF as M37 x P3.0 that's really over priced and not the style I was looking for, Any help is appreciated.

That's a first.

Update I've since bought one of these aftermarket oil caps that was marked M37 3.0 and it fit nicely.
