The sensor threads directly into the exhaust manifold or exhaust pipe at the factory location — no modification needed.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this sensor come pre-gapped or ready to screw in?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, it's ready to install straight out of the box. Just apply a thin coat of anti-seize compound to the threads (especially if your exhaust runs hot), thread it in by hand first, then torque it down snug — refer to your service manual for the exact torque spec.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp\u003e\u003cstrong\u003eWhat if the check engine light came back after I installed a sensor before?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA new sensor won't clear a stored code on its own — you'll need a scanner to clear it after installation. If the light returns immediately, the issue may be elsewhere in the fuel trim or emissions system. A failing catalytic converter or vacuum leak can trigger oxygen sensor codes even with a good sensor in place.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"K2 Industries","offers":[{"title":"Default Title","offer_id":45874493358314,"sku":"K2-10837-NIS-006-EC","price":109.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0477\/0427\/7142\/files\/OEM-SS-073-1.jpg?v=1772777952","url":"https:\/\/www.k2-industries.com\/en-au\/products\/sensor-02-03-nissan-altima-2-5l-3-5l-00-06-nissan-sentra-1-8l-2-5l-front","provider":"K2 Industries","version":"1.0","type":"link"}
