GSC P-D Mazda Miata 1.6L/1.8L Manganese Bronze Intake/Exhaust Valve Guide +.001in Oversize - Single

This is a single GSC Power Division Manganese Bronze valve guide for Mazda Miata models with 1.6L or 1.8L engines. It's designed as a +.001 inch oversize replacement, meaning it's slightly larger than stock to help tighten up valve stem-to-guide clearance. This is often done during an engine rebuild or when you notice excessive oil consumption or poor valve sealing.

Manganese bronze is a good material for valve guides because it's durable and has good self-lubricating properties, which helps reduce wear over time. This guide is intended for either intake or exhaust applications, giving you flexibility during your engine work. Because it's an oversize part, you'll want to ensure your valve stems are the correct size for a proper fit, or that you're reaming the guide to the correct size for your specific valve stems.
