The 65mm dimension on this piston is the detail that separates serious inquiries from casual ones. Reference 0418 3269 belongs to the BF12L513 air-cooled V12 family, a platform where piston geometry directly affects combustion sealing and thermal behavior under continuous load. We produce this reference at our own plant rather than sourcing from open market stock, which means we can speak to the dimensional constraints of the 65mm specification without redirecting you to a third-party spec sheet. For rebuilders working on 513-series engines in construction or power generation, the question is rarely “is it available” but “is it the right geometry”—and that is the conversation we are set up to have.
