2 PCS-Stainless Steel Catalytic Converter Adapter - M18X1.5, Solves P0420/P0430 Codes​(T61)

Upgrade your vehicle’s exhaust system with this high-performance oxygen sensor thread adapter, engineered to solve check engine light issues during modifications. Crafted from SS304 and stainless steel, it’s built to withstand extreme temperatures, vibrations, and corrosion—making it a durable choice for off-road adventures and daily use.​ With precise dimensions (23 mm hexagonal size, 50 mm length) and M18*1.5 threading, it fits seamlessly with standard oxygen sensors, ensuring a secure connection without leaks. Its standout feature is the built-in micro catalytic converter, which outperforms unreliable extensions: when you modify your exhaust, remove the catalytic converter, or install a high-flow version, this adapter fools the ECU into thinking the original catalytic converter is still active. This prevents check engine lights and resolves error codes like P0420 and P0430, keeping your vehicle running smoothly.​ Installation is straightforward, making it suitable for both professionals and DIYers. Choose the 1-pack for a single vehicle or spare, or the 5-pack for workshops, fleets, or multiple projects—either way, you’ll get reliable performance and peace of mind.​ Package includes 1 or 5 oxygen sensor adapters (depending on your choice). Add this essential accessory to your toolkit and enjoy hassle-free exhaust modifications.​
