FAQ

Q: What do intake and exhaust valves do?

A: Intake valves admit air (or air-fuel mixture) into the cylinder; exhaust valves discharge burnt gases. Both are driven by the camshaft and must seal tightly against the valve seat to maintain compression and combustion efficiency.

Q: When should I replace valves?

A: Replace when valve faces are burnt, warped, or worn beyond service limits, or when valves fail to seat properly causing compression loss or abnormal engine noise.

Q: OEM or aftermarket?

A: High-quality aftermarket at OEM equivalent standard.

Q: What is the lead time?

A: 3-5 working days for in-stock orders; 7-15 working days for bulk orders.

Q: What payment methods do you accept?

A: We accept T/T (Telegraphic Transfer). Other payment methods may be available upon request for qualified buyers.

Q: Packaging options?

A: OEM, neutral, or custom packaging available.
