FAQ
Q1: Will these valve seats fit my Mitsubishi S4S engine without modification? Yes, these valve seats are manufactured to OEM dimensions (32A01-03100/32A01-03110) and are direct replacements. However, we recommend professional installation using a valve seat cutter to ensure perfect seating if the cylinder head has been reconditioned.
Q2: What is the difference between 32A01-03100 and 32A01-03110? 32A01-03100 typically refers to the intake valve seat, while 32A01-03110 is the exhaust valve seat. Exhaust seats often have slightly higher heat resistance. Always replace both as a set for balanced performance.
Q3: Do you provide bulk discounts for engine rebuild shops? Yes, we offer tiered wholesale pricing for orders of 50+ pieces. Contact our sales team for a customized quote with shipping to your region. We also support drop-shipping for international distributors.
