X300701 Intake Valve is a precision opening and closing component for JAC YND30TCI diesel engine cylinder head. It cooperates with camshaft and valve spring to control fresh air entering the combustion chamber at the correct timing, laying the foundation for stable fuel combustion. This aftermarket replacement intake valve solves insufficient air inflow, weak power output, rough idle and black smoke caused by valve head burning, stem wear, sealing surface depression and valve bending of old valves. Good air intake matching improves combustion efficiency and reduces fuel consumption for light trucks working on heavy-load delivery and variable-speed driving conditions.
Product AdvantagesMade of high-temperature resistant alloy steel with nitriding treatment, with excellent heat resistance and abrasion resistance. Precision grinding on valve face ensures tight sealing with valve seat. Straight valve stem reduces friction with valve guide and prevents jamming. Each intake valve undergoes concentricity inspection and surface defect screening before shipment, OEM size for direct replacement during valve overhaul.
