    We have a strong R&D team,and we can develop and produce Lawngarden spark plugs thread size 14mm L7 according to the drawings or samples the customers offered.

  • Cost

    We have our own ceramic factory and processing plant,ceramic Insulators are completely self-produced,so we can offer the good price and Lawngarden spark plugs thread size 14mm L7 directly.

  • Quality

    We draw on the principles of the advanced international quality management system with which its concepts of quality control are well integrated, as it puts the quality control under rigorous supervision during the whole production process.We also have our own testing lab,Repeatedly tested with the advanced equipment in the industry.

  • Multiformity

    We boast the world’s cutting-edge isostatic pressing process for ceramics insulator,Introduce the German 360-degree laser welding machine, Japanese special powder filling cold lock technology are also introduced to the production process,it can meet different shapes, different sizes, different materials of product development and production,also packaging a large number of types.

  • Capacity

    It is providing the global market with more than 300 models with an annual output of more than 80 million models in various types, which makes it to emerge as one of the solid and developed enterprises as well as an indispensable player in the spark plug manufacturing industry chain.

    The company has obtained several industry qualification certificates such as IATF16946, EU TUV, RoHS, etc. The products are exported to Europe, America, Middle East, Southeast Asia, and other countries.

Marshal Auto Parts Co., Ltd has a variety of product lines for Spark Plugs manufacturing , engineering and technical capabilities and manufacturing capabilities are in constant progress.

We are well known Lawngarden spark plugs thread size 14mm L7 Suppliers and Lawngarden spark plugs thread size 14mm L7 company. 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.

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 dissapation, better ablation resistance.Shells have better malleability,better toughness, higher hardness which can reduce shell breaking and help the shell for better heat disappation.

In terms of experimental capacity, the laboratory fully complies with and strictly implements 17 international and national spark plug industry test standards; enterprise internal control standards more than 34 original supporting level type test; process inspection 100% coverage of the whole process of control points.

In quality management has obtained the quality management system certification.

Company for some spark plugs and design patent certificate, utility model patent certificate. We custom Lawngarden spark plugs thread size 14mm L7.
