If you're sealing a B-series oil pan, the genuine Honda OEM gasket (part #11251-P30-004) is the only replacement that matches the exact flange geometry, material durometer, and compression tolerance Honda engineered into your engine. Aftermarket alternatives cut corners on material spec - that's why you see oil seepage come back within a season on a lot of B-series builds that used a cheaper gasket the first time around.
This is a direct OEM replacement, not a rebranded aftermarket part. The rubber-coated steel construction holds its seal under the heat cycling a B-series sees in both daily-driver and track use. It compresses evenly across the full perimeter of the oil pan flange, which is the part that cheap gaskets consistently get wrong.
Compatible B-Series Engine Codes: B16A, B16A2, B16B, B18B1, B18C, B18C1, B18C5, B20B, B20Z
Installation Notes: No gasket maker or RTV sealant is required with this OEM gasket - Honda designed it to seal dry. Torque oil pan bolts to Honda spec (typically 8-12 Nm / 6-9 ft-lb depending on engine variant - always verify with your service manual). The job runs 30-45 minutes with a standard socket set and a drain pan. Clean the mating surfaces thoroughly before install.
This gasket fits a wide range of Honda and Acura chassis from 1988 through 2001. See the full fitment list below before ordering. If you're pulling the oil pan for a rebuild, rod bearing service, or oil pump replacement, this is the correct OEM gasket to have on the bench before you button it back up.
