This ad is for a radiator cap COVER. You will not be receiving an actual radiator cap. This water cap cover is CNC machined for precise fitments. There are many other after market water caps replacements. However, my water cap covers let you keep the "original OEM cap""!! Since the after market caps are not as good as the original ones, APC came up with this brilliant idea of there billet covers that go over the original caps. Screws tight with allen wrench (not included). The compatibility list I have provided is for the radiator cap itself (part # 19045-PAA-A01). If you do not have the original OEM cap, please make sure that you look at the pictures and see that this will fit your cap. The longest inner dimensions are 1 3/4" long x 2 3/4" wide.
