Almost identical to OEM. Good fit. I did miss that they are sold as each and not as a pair. Small detail and my fault but it did slow my project down a bit.

Frequently Asked Questions
Is this the correct gasket for my Softail?
Yes, if your bike has an M8 (Milwaukee-Eight) engine and uses OEM part number 25701. Verify the OEM number matches before ordering.
Do I need any special tools to install this?
Installation requires standard gasket removal and surface prep. No specialized tools needed beyond basic wrenches and a gasket scraper.
What's the difference between molded rubber and paper gaskets?
