Common questions
What does +0.002 inch oversized mean?
This guide is machined 0.002 inches larger in diameter than a standard guide. It is specifically intended for cylinder heads where the original valve guide bores have worn beyond the tolerance for standard or +0.001 oversized guides.
Is this valve guide for exhaust or intake valves?
This KPMI component is an exhaust valve guide. If you need an intake guide, you will need to order a separate part number designed for that position.
Do I need any special tools to install this?
Yes, installing valve guides requires specialized tools such as a valve guide driver or a press. This type of work is typically performed by experienced engine builders or professional machine shops.
