Common questions
Will this valve guide fit my 2012 or newer Twin Cam engine?
No, this KPMI intake valve guide is specifically designed for 2005-2011 Twin Cam 88 and 103 cubic inch engines. 2012 and newer Twin Cam models use different guide specifications.
Is this an intake or exhaust valve guide?
This KPMI part number is an intake valve guide. KPMI offers separate part numbers for exhaust valve guides.
Do I need to replace both intake and exhaust guides?
Not necessarily. You should replace only the guides that are worn beyond service limits. Many riders replace intake guides only if exhaust guides are still within specifications, but it's best to assess both during a cylinder head inspection.
