FAQ

Q1: How can I be sure these valves will fit my engine?
A1: These valves are specifically designed to be a direct replacement for the Isuzu 4JG1 engine. The fitment is confirmed by the OEM part numbers: 8-94133-275-1 for the intake and 8-94247-875-1 for the exhaust. To be 100% certain, please remove one of your old valves and compare it physically, or check the part number stamped on the head of your existing valve against the numbers listed.

Q2: Do I need to replace the valve guides and seals at the same time?
A2: While not strictly required, it is a best practice in engine rebuilding to replace the valve guides and valve stem seals whenever you install new valves. Worn guides can cause the new valve to seat improperly, leading to premature failure. Replacing them all together ensures a complete and reliable top-end overhaul.

Q3: What is the difference between the intake and exhaust valves in this set?
A3: The intake valve (8-94133-275-1) and exhaust valve (8-94247-875-1) are different parts designed for different conditions. Exhaust valves are typically made from materials that can withstand higher temperatures than intake valves. This set provides the correct, specific valve for each position, ensuring optimal engine performance and longevity. Do not mix them up during installation.
