Product Details

📝 Product Description

Tired of the Check Engine Light popping up after modifying your exhaust? This O2 sensor spacer features a built-in mini catalytic converter, which helps reduce CEL and tricks the ECU into thinking your emissions system is still stock.

Unlike cheap extensions that often fail, this one actually works — thanks to the internal catalytic element. It reduces exhaust flow and temperature directly hitting your rear O2 sensor, helping avoid error codes like P0420 and P0042.

Perfect for off-road or performance vehicles that have removed or replaced the factory catalytic converter.
