OYP003 Spark Plug Thread and Injector Repair Set

The OYP003 Spark Plug Thread and Injector Repair Set is a specialised thread repair kit focused on the specific thread sizes and applications most commonly encountered in engine top-end service — namely spark plug bore thread repair and diesel injector thread restoration. The set includes components for spark plug sizes 10 mm, 12 mm, 14 mm, and 18 mm, compatible with a wide range of petrol and gasoline engine makes including Alfa Romeo, BMW, Chrysler, Citroën, Daewoo, Fiat, Ford, Honda, Hyundai, Isuzu, Jeep, Kia, Lada, Lancia, Land Rover, LDV, Mazda, Mercedes-Benz, MG, Mitsubishi, Nissan, Peugeot, Renault, Rover, Saab, Ssangyong, Suzuki, Toyota, VAG and Vauxhall/Volvo.

The injector adapter component covers injector thread sizes M20, M22, M24, and Ford Stanadyne injectors plus clamp-on injector types, addressing the common thread damage scenarios encountered during injector removal in diesel engine service — particularly on high-mileage vehicles where corrosion can cause injector seizure and thread damage during extraction. The inclusion of both spark plug and injector repair coverage in a single set makes the OYP003 a versatile top-end engine thread repair resource.

This set is suited to general automotive repair workshops, engine specialists, and diesel service businesses that encounter spark plug thread damage and injector bore thread repair as part of their regular workflow. Stripped spark plug threads and damaged injector bores are among the more costly failures if not repaired correctly, and having the appropriate specialised thread repair tools on hand allows these jobs to be completed efficiently in-house without outsourcing to machine shops or replacing cylinder heads unnecessarily.
