Replacement Oil Filler Cap, Aftermarket Fit

A worn or missing filler cap lets dirt into the oil fill neck. This is a plastic replacement built to the dimensions of accessory number 12513-P72-003, fitting certain CR-V, Odyssey, and Accord engines rather than acting as a universal one-size cap. It is black, ships in a single version, and comes to 30 grams, light enough that it adds no meaningful heft under the hood. Press it in. Lugs around the rim locate it in the neck and hold it there once turned. Because it matches a specific accessory number rather than a broad range of engines, check the number stamped on the original cap before ordering. A close-looking cap from a different model year will not always seat the same way, even one that looks right at a glance across a parts counter.
