FAQ

Q1: Is this cylinder head a direct bolt-on replacement for my Mitsubishi K3E engine?
A: Yes, this MM408450 cylinder head is a direct OEM replacement. It comes complete with valves, springs, and seats pre-installed. However, we recommend checking your old part number and comparing the head gasket surface to ensure compatibility with your specific engine serial number.

Q2: What maintenance steps are critical when installing a new cylinder head?
A: Always use a new head gasket and new cylinder head bolts (stretch bolts are single-use). Clean the engine block surface thoroughly. Torque the head bolts in the correct sequence and to the specified stage (e.g., 1st stage 40 Nm, 2nd stage 90 degrees). We recommend consulting your engine service manual for exact specifications.

A: We accept returns within 30 days of delivery for unused and undamaged parts. Please provide clear photos of the part and your engine for verification. We will issue a full refund or exchange, minus shipping costs. We highly recommend verifying fitment with our sales team before ordering to avoid delays.
