Common questions
What does the +0.010 inch oversize mean for this valve guide?
The +0.010 inch oversize indicates that the guide's outer diameter is 0.010 inches larger than stock. This is typically used when the cylinder head's guide bore is significantly worn and requires a larger guide for a proper press fit after reaming.
Is this valve guide for intake or exhaust applications?
This KPMI part is an intake valve guide only. Exhaust valve guides have different specifications and require a separate part number.
Will this guide fit my 2011 or newer Twin Cam engine?
No, this specific guide is designed for 2005-2010 Twin Cam 88 and 103 cubic inch engines. Newer Twin Cam models utilize different cylinder head designs and require alternative valve guides.
