The Supertech precision-machined, high quality Maganese Bronze Valve Guides used in combination with their low friction nitrided valves provide the best solution for performnace and durability for your 4G63 motor.
Oversized guides (+.03mm) are for the O.D., not the I.D. for the valve stem. These are required if your guides have been removed numerous times and the head has lost enough material where the holes have gotten larger.
The inner diameter for these guides is 6.6mm and pairs with Supertech 6.6mm Valve Seals.
