O2 sensors are installed at specific locations in the exhaust system and send information to the engine control module (ECM\/ECU), which uses this data to monitor and adjust engine operation and emissions performance.\u003c\/p\u003e\n\u003cp\u003eFor gasoline engines, the ideal stoichiometric air-fuel ratio is approximately 14.7 parts air to 1 part fuel under appropriate operating conditions. The O2 sensors provide feedback that helps the engine management system maintain proper operation, fuel efficiency, performance, and emissions.\u003c\/p\u003e\n\u003cp\u003eA straight O2 sensor spacer is installed between the O2 sensor and the exhaust system. Unlike a J-style or angled spacer, the straight design keeps the sensor positioned directly in line with the threaded mounting location, providing additional spacing between the sensor and the exhaust stream.\u003c\/p\u003e\n\u003cp\u003eAfter installing an aftermarket exhaust component such as a downpipe, header, or other exhaust section, a straight O2 sensor spacer may be used for several reasons:\u003c\/p\u003e\n\u003cp\u003eFitment and Clearance:\u003cbr\u003eThe straight spacer provides additional distance between the O2 sensor and the exhaust pipe while maintaining a simple inline configuration. This can be useful when additional sensor spacing is required and there is sufficient clearance around the mounting location.\u003c\/p\u003e\n\u003cp\u003eInstallation:\u003cbr\u003eThe straight design threads directly into a compatible O2 sensor bung, with the O2 sensor then installed into the spacer. Its inline configuration provides a straightforward installation without the angled shape of a J-style adapter.\u003c\/p\u003e\n\u003cp\u003eAftermarket Exhaust Applications:\u003cbr\u003eChanges to the factory exhaust system can alter exhaust flow and the conditions experienced by the O2 sensor. A straight spacer may be used as part of an aftermarket exhaust installation where additional sensor spacing or positioning is required.\u003c\/p\u003e\n\u003cp\u003eSensor Protection and Positioning:\u003cbr\u003eDepending on the application, the spacer can help position the sensor farther away from the main exhaust stream and provide additional separation from extreme exhaust heat and flow.\u003c\/p\u003e\n\u003cp\u003eBefore installation, always verify the thread size, available clearance, sensor location, and vehicle compatibility. Installation of aftermarket exhaust components or O2 sensor spacers may affect emissions compliance and may not be legal for street use in certain areas. Always check applicable local and federal regulations before installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProfessional Installation is HIGHLY Recommended!\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0622\/4009\/6449\/files\/EOS_480x480.jpg?v=1680043242\"\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"Universal Compatible","offers":[{"title":"Default Title","offer_id":50644468728001,"sku":"EXT-OS129","price":37.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0622\/4009\/6449\/files\/CPNW_ca511abf-5d6a-4afa-be85-209fb3b9d934.jpg?v=1791837643","url":"https:\/\/eosexhaust.com\/en-ca\/products\/eos-exhaust-straight-o2-performance-oxygen-sensors-restrictor","provider":"EOS Exhaust","version":"1.0","type":"link"}
