DO NOT USE Z9!!! although it may screw on.. ITS A 3/4 SAE THREAD AND THE NISSAN Z115 AND Z170 ARE 19MM,z170 is a short version of the z115 the z170 is use for clearance issues when height is a problem ( the only time a z9 would be seen on a nissan would be if a universal oil filter relocation kit is used , they commonly spin on z9, purely as an availability thing)
