Brass M18x1.5 90° Oxygen Sensor Bung Extension Angled Spacer

Precision-machined brass oxygen sensor bung extension creates a 90° offset to reposition sensors without modifying exhaust systems. Internal and external M18 x 1.5 threads provide a secure, OEM-compatible fit for vehicles using standard M18x1.50 sensor fittings. The angled spacer measures approximately 1.61 inches tall and extends the sensor away from hot components to reduce heat exposure and prevent false readings. Solid brass construction resists corrosion and maintains electrical grounding for accurate sensor signals over extended service life. Installation is straightforward with hand-tighten and torque options; the included crush washer ensures a gas-tight seal. This extender preserves factory sensor orientation while enabling aftermarket sensors or installations that require clearance. Universal compatibility covers most M18x1.5 oxygen sensor applications across exhaust systems and rear placements. Low-profile design minimizes exhaust interference and maintains exhaust flow characteristics while protecting the sensor head. Suitable for repair shops and DIY technicians seeking a reliable, long-lasting solution to sensor clearance issues. Sold individually; inspect thread condition and torque to manufacturer specifications when installing to ensure leak-free performance.
