CTS CEL Eliminator / O2 Sensor spacer

The CTS Turbo CEL Eliminator and O2 Sensor Spacer provides a straightforward solution for eliminating check engine lights triggered by aftermarket exhaust modifications. By repositioning the downstream oxygen sensor further from the exhaust stream, this precision-machined spacer reduces sensor sensitivity to changes in emissions readings. Essential for workshops performing cat deletions or high-flow catalytic converter installations, it helps maintain clean diagnostics without compromising engine management function. Manufactured from quality materials with proper thread specifications for reliable long-term installation.
