Do yourself a favor and get a genuine Honda gasket. This has a pretty serious design flaw, as noted by another reviewer, the holes aren't punched properly. I went through two of these washers - using the factory installation procedure, tightening to 9 in/lbs in three increments with a calibrated torque wrench. Both failed after about ONE MONTH. Used a factory Honda gasket (also from Revain, part number 11251-P2A-014) and it held up.
