About this item

• 【M18 x 1.5 Universal Thread Design】: This 2-Pack O2 sensor spacer set is designed with M18 x 1.5 threads, a common oxygen sensor thread size for many vehicles. Please confirm your sensor thread and installation space before purchase for proper fitment.
• 【May Help with P0420 P0430 Related Readings】: Designed for diagnostic, off-road or competition use, this spacer may help reduce check engine light issues related to catalytic efficiency readings such as P0420 or P0430. Results may vary depending on vehicle condition and exhaust setup.
• 【46mm Straight Spacer with Mini Catalytic Insert】: Each oxygen sensor extender measures approx. 46mm and includes a built-in mini catalytic insert, helping move the sensor away from the direct exhaust stream for modified exhaust, high-flow catalytic converter or aging catalytic converter setups where permitted.
• 【Compact 45-46mm Fitment Advantage】: Compared with longer 60mm spacers, this shorter straight design is easier to install in many underbody areas and helps reduce interference with heat shields, wiring or tight exhaust spaces, making it a practical choice for wider fitment.
• 【2-Pack Set for Practical Installation】: Package includes 2 oxygen sensor spacer adapters with mini catalytic inserts. Product size is approx. 7 x 3 x 1.5 cm and total weight approx. 85 g. Professional installation is recommended, and users should follow local emissions regulations.
