Supertech Nissan VQ35 Intake/Exhaust Guide - 10.079mm OD x 42mm L x 5.985mm ID - Manganese Bronze

This Supertech valve guide is what you get when you order part number GDE-NVQ35. It's a manganese bronze valve guide designed for Nissan VQ35 engines, measuring 10.079mm in outer diameter, 42mm in length, and 5.985mm in inner diameter. This part is crucial for proper valve operation, ensuring the valve moves smoothly and stays aligned within the cylinder head.

Manganese bronze is a solid material choice for valve guides because it offers good wear resistance and lubricity, which helps reduce friction and heat buildup. This can contribute to longer valve and guide life, especially in engines that see regular use or are being rebuilt for performance. Proper valve guide function is key to maintaining good compression and preventing oil from leaking past the valve stem into the combustion chamber.
