Simulateur de catalyseur pour sonde Lambda

Description

Having problems with a check engine light (CEL)? Our oxygen sensor extension with catalytic core offsets the oxygen sensor about 1.75 inches from the exhaust gas stream. This achieves, in most cases, a sufficient measurement for the air/CO ratio and increases the tolerance range between the pre and post oxygen sensors. In addition, the sensitivity of the oxygen sensor is also reduced, allowing you to run most exhausts.

Sold individually.

Please note: Only for use on the downstream or 2nd oxygen sensor (after catalytic converter). This fits multiple Porsche models, please check the model fitment tab to ensure accurate fitment.
