FAQ

Q1: How do I confirm these valves will fit my specific Isuzu 4HK1 engine?
A1: The surest method is to cross-reference the part number currently on your valve or from your engine’s parts catalog. The primary numbers for this set are 8-94395882-0 (intake) and 8-97209873-0 (exhaust). Providing your engine’s serial number to our technical team can also help verify compatibility.

Q2: Are these valves sold individually or as a full set for one engine?
A2: These valves are typically sold as individual units. Please specify the quantity (intake or exhaust) required for your project. A complete set for a 6-cylinder 6HK1 engine, for example, would require 6 intake and 6 exhaust valves.

Q3: What is the recommended maintenance practice when replacing these valves?
A3: For optimal performance and longevity, we strongly recommend replacing valve stem seals, inspecting and potentially re-facing the valve seats, and checking valve spring tension during installation. Always follow the engine manufacturer’s specified torque procedures and clearance settings.
