Product Details
Bring worn, corroded or cross-threaded lambda (O2) sensor ports back into service with this 2-piece thread repair kit. It’s designed to help you restore the thread in the exhaust boss so the sensor can be refitted securely, saving time and avoiding unnecessary part replacement.
Made from durable steel, the taps are built for repeated use in workshop conditions. Each tool is intended to chase and reform existing threads, helping to clear debris and correct minor damage for a cleaner, more accurate fit.
Suitable for common oxygen sensor thread types used across a wide range of vehicles, this kit is a practical choice for exhaust repairs, sensor replacement jobs and general diagnostic work.
Use it when fitting a new sensor, dealing with seized or damaged threads, or tidying an older exhaust port during maintenance. Always work carefully, keep the tool aligned to the original thread, and apply an appropriate cutting fluid to help achieve the best finish.
This set includes two thread repair taps, giving you coverage for the most frequently encountered lambda sensor port sizes in one compact kit.
