Core Selling Points
High-demand complete valve set for engine overhaul
It is a top-selling matching valve kit for CBZ 1.2T engine maintenance. Long-term high-temperature operation easily triggers valve burning, sealing failure and power loss. Repair shops and auto parts wholesalers maintain continuous repeat bulk orders, bringing steady sales and stable profit margins for distributors.
OE-standard full dimensional accuracy
Produced strictly following OEM machining standards. Valve head diameter, stem thickness, sealing taper angle, collet groove position and overall length are 100% consistent with original valves. Direct installation without grinding, cutting or extra valve seat rework.
Differentiated high-temperature alloy material
Intake valve: Heat-resistant alloy steel with anti-oxidation surfacing, resistant to high-temperature intake air erosion;
Exhaust valve: Special heat-resistant nickel alloy with hard surfacing on sealing cone, superior anti-ablation performance under high-temperature exhaust gas impact.
Both valves feature excellent wear resistance and anti-deformation capability, avoiding premature burning and air leakage.
Precision sealing recovers original engine performance
Ultra-fine machined sealing cone fits tightly with valve seat rings, effectively eliminating air leakage. Solves common issues such as insufficient power, unstable idle, rising fuel consumption and excess exhaust emissions.
Fix typical valve system failures
Perfectly resolves faults including burnt valve heads, worn valve stems, poor compression sealing, rough idle and engine power attenuation, extending the overall service life of the valve train assembly.
Rigorous multi-process quality testing & sufficient spot stock
Every valve set undergoes dimensional inspection, hardness test, air tightness test and high-temperature aging test before delivery to guarantee long-term reliable service life. Mass ready stock supports fast bulk shipment. Custom neutral packaging and private label services are available to meet cross-border wholesale demands.
