Overview

The Kooks Oxygen Sensor Spacer is a stainless steel component designed to extend the reach of your O2 sensor. This spacer measures 1-3/4 inches in length and features universal M18 x 1.5 threading for various exhaust system applications.
Show original supplier description
Measuring 1-3/4 inches in length, this extension is designed to address fitment challenges where sensors require additional space, particularly when using performance headers or modified exhaust configurations. It features standard M18 x 1.5 threads to ensure compatibility with most factory and aftermarket O2 sensor bungs. Crafted by Kooks Headers and Exhaust, this spacer is manufactured in the USA using durable stainless steel to withstand the high-temperature environment of an exhaust stream. As a universal fitment component, it does not have specific vehicle application data and should be verified manually to confirm compatibility with your specific exhaust setup. The part is frequently utilized alongside performance exhaust upgrades to ensure proper sensor positioning and functionality.
