Spark Plug Base

This spark plug base is made of high-temperature resistant rubber composite material. It adds built-in reinforcing liner to maintain stable shape under engine heat. The precise inner and outer diameter realizes seamless fit with spark plug and cylinder head.

It owns dual functions of sealing and vibration isolation. It effectively blocks engine oil leakage and prevents dust from entering the ignition area. It absorbs operating vibration to protect spark plug from loose displacement during long-term driving.

All products pass strict high-temperature aging and compression tests. They match most passenger car and light truck engine models. We provide consistent dimensional accuracy and stable bulk supply for auto aftermarket replacement.
