a 97 I30 w/ a VQ30, a 2k2 Max w/ a VQ35 and a 91 Q45 (mine) with a VH45de.
The two Infiniti's had the billet Stillen oil caps, and the 2k2 Max the stock oil cap.
I thought it would be cool to play around, so I took out my oil cap and it fit the VQ30 and the VQ35 too!!And we switched them around any which way and they fit!
Cool trivia huh?
