If your vehicle's downstream oxygen sensor uses this thread size, this adapter will fit without any additional modification.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Will this spacer help eliminate a check engine light (CEL)?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — the spacer features an internal stainless steel mesh filter designed to help prevent false catalyst-efficiency fault codes from triggering the CEL on vehicles with downstream oxygen sensors. It does not address other fault codes unrelated to catalyst efficiency.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is any special tool required to install this oxygen sensor spacer?\u003c\/h4\u003e\n\u003cp\u003eA: No special tools are required for most installations. The M18x1.5 threads allow hand-tightening to start, and a standard oxygen sensor socket or wrench can be used to fully secure it. Installation is straightforward and typically takes only a few minutes.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What material is the spacer made from, and is it heat-resistant?\u003c\/h4\u003e\n\u003cp\u003eA: The spacer is machined from high-grade stainless steel with a polished silver finish. Stainless steel is inherently heat-resistant and corrosion-resistant, making it well-suited for the high-temperature exhaust environment where O2 sensors operate.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What vehicles is this M18x1.5 oxygen sensor spacer compatible with?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This spacer is universally compatible with any vehicle that uses a standard M18x1.5 thread pitch O2 sensor bung.
