Frequently Asked Questions
Q: What vehicles is this M18 x 1.5mm O2 sensor spacer extender compatible with?
A: This 135-degree elbow oxygen sensor spacer adapter is designed to fit any vehicle with a standard M18 x 1.5mm threaded oxygen sensor bung. This is one of the most common thread sizes used across a wide range of gasoline-powered passenger cars, trucks, and performance vehicles. Always verify your existing bung thread size before installation.
Q: Why would I need a 135-degree elbow O2 sensor spacer extender?
A: A 135-degree elbow spacer extender is ideal when your exhaust bung is positioned in a tight or awkward location — such as in high-clearance headers, aftermarket exhaust systems, or areas with limited straight-line access. It repositions the oxygen sensor at an optimal angle for a cleaner installation and better sensor access during future maintenance.
Q: Is this O2 sensor spacer extender easy to install myself?
A: Yes. The precision M18 x 1.5mm threads are machined for smooth engagement, allowing most DIY mechanics and automotive enthusiasts to complete installation with standard tools. Thread the adapter into your existing bung, then thread your O2 sensor into the adapter's receiving port. Always ensure threads are clean and use appropriate thread sealant if needed to prevent exhaust leaks.
Q: What is the maximum pressure rating for this adapter?
A: This extender adapter is rated for pressures under 850 kPa, making it suitable for standard automotive exhaust applications. It is constructed from galvanized carbon steel for durability and corrosion resistance in high-heat exhaust environments.
