Oxygen sensor spacers move oxygen sensors away from direct contact with exhaust flow. They are usually installed on rear sensor bungs(ie. downstream of catalytic converters) on aftermarket exhaust pipes to remedy the CEL (Check Engine Light) problems(effectiveness varies for different vehicles with different equipments). They are often seen paired with catless test pipes, mid-pipes with high flow racing cats, or straight pipes.
IMPORTANT: Choose the appropriate type of spacers to avoid clearance issues.
