Frequently Asked Questions

What makes Black Diamond different from chrome-plated valves?

Black Diamond uses a German impregnation process that penetrates .002″ deep, providing superior wear and corrosion resistance compared to surface plating.

Will this fit my 2004 or earlier Twin Cam?

This part is for 2005-2010 Twin Cam 88 and 103 engines. Confirm your engine displacement and model year before ordering.

Is this an intake or exhaust valve?

This is an exhaust valve. Verify you need exhaust rather than intake before purchasing.

Can I use just one valve or do I need a full set?

Individual valves are available. Confirm your engine configuration and which position (intake or exhaust) needs replacement.
