This Sixity Auto 6‑pack of NGK V‑Power spark plugs suits Jeep TJ owners (1997–2006) who want a reliable, budget‑minded tune‑up for the 4.0L inline‑6. It’s ideal for daily drivers, weekend trail rigs, or any TJ with moderate mileage where replacing worn plugs can deliver immediate improvements in starting, throttle response, and idle stability. If you’d prefer the longest service life and highest heat‑range resilience, consider NGK’s iridium options; for straightforward, economical replacement and easier maintenance, these V‑Power plugs are an excellent match.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eProduct highlights:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eGenuine NGK parts packaged in a Sixity Auto 6‑pack\u003c\/li\u003e\n  \u003cli\u003eEconomical performance plug tailored for older vehicles\u003c\/li\u003e\n  \u003cli\u003eV‑groove tip and high‑performance nickel electrode for improved spark\u003c\/li\u003e\n  \u003cli\u003eTrivalent metal plating for superior anti‑corrosion and anti‑seize protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will these fit any Jeep TJ 4.0L between 1997 and 2006?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, this Sixity Auto pack contains the correct NGK V‑Power plugs specified for Jeep TJ 4.0L inline‑6 engines from 1997–2006.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need special tools to install these spark plugs?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: You only need a spark plug socket, ratchet, and a torque wrench; check gap first and hand‑start to avoid cross‑threading.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Sixity Auto","offers":[{"title":"Default Title","offer_id":48086770745502,"sku":"B01N14INC7","price":54.92,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/sixity-auto-ngk-vpower-front-packaging_d7a61472-303d-4625-89a7-bbdb54aada10.jpg?v=1785904364","url":"https:\/\/northtrailauto.ca\/products\/sixity-auto-ngk-v-power-spark-plugs-6-pack-for-jeep-tj-4-0l-1997-2006-v-groove-tip-anti-seize-plating","provider":"North Trail Auto","version":"1.0","type":"link"}
