O2 Sensor Spacer — Stainless, M18 x 1.5 | Straight or 90°

Stainless steel O2 sensor spacers, available in two styles to suit the space around your sensor: Straight or 90° angled. They're a simple screw-in fix that moves the rear (downstream) O2 sensor out of the direct exhaust flow, a common fix after fitting a catless or high-flow downpipe, header or cat-back.

STYLES

• Straight: screws straight into the bung. Includes the mini catalyst insert and a removable 7-hole flow cap.
• 90° angled: turns the sensor 90° for tight tunnels, heat shields and low-clearance spots.

SPECS

Thread: M18 x 1.5, the standard O2 sensor bung and sensor thread used on most petrol cars. Material: stainless steel. Sold individually. Price is per spacer.

FITMENT (PERTH)

Universal fit for M18 x 1.5 O2 sensors. Local to Perth? We can fit it in-house, along with the downpipe, cat-back or tune it's going with. Just ask when you order.

Please note: O2 sensor spacers are intended for off-road / competition use. Results vary by vehicle and ECU. Some cars will still need a tune to clear an engine light. Not for use on road-registered vehicles where emissions equipment must remain functional.
