Marshal Auto Parts Co., Ltd has a variety of product lines, engineering and technical capabilities and manufacturing capabilities are in constant progress. In terms of engineering skills,30 years develop and reverse engineering experience. Electrode has PASS TUV ,CONFORM TO RoHs Reach.High strength insulator use a 360°Continuous Laser technology. Marshal Auto Parts Co., Ltd is famous China Spark Plugs Manufacturing Company and wholesale Spark Plugs factory. In manufacturing, it also has a ceramic factory. Ceramic Insulators are completely self-produced, high density of insulator, better dielectric strength, thicken design of insulator nose, better mechanical strength which can satisfy modern engine well. Secondly, electrodes have better electrical conductivity, better heat resistance, better heat dissipation, better ablation resistance. Shells have better malleability, better toughness, higher hardness which can reduce shell breaking and help the shell for better heat dissipation. Support OEM Products.
