NGK spark plugs offer higher performance compared to standard plugs. NGK spark plugs feature a V-groove center electrode and concave ground electrode that lowers ignition voltage requirements while guiding the spark to occur between the sharper outside edges of the electrodes for improved ignitability and performance.\u003cbr\u003e\u003cbr\u003eElectrode Material: Nickel\u003cbr\u003eThread Size: 0.551\"\u003cbr\u003eThread Reach: 0.708\"\u003cbr\u003eGround Electrode Quantity: 1\u003cbr\u003eGap: 0.060\"\u003cbr\u003eSpark Plug Seat Style: Tapered\u003cbr\u003eHeat Range: 5\u003cbr\u003eLongevity: 30k Miles\u003cbr\u003eThread Diameter: 14 mm\u003cbr\u003eOverall Height: ISO\u003cbr\u003eResistance: 5 kOhm\u003cbr\u003eInsulator Height: 53 mm\u003cbr\u003eCenter Electrode Core Material: Copper Core\u003cbr\u003eGround Configuration: Standard\u003cbr\u003eGround Electrode Core Material: Nickel Core\u003cbr\u003eGround Electrode Tip Design: Standard\u003cbr\u003eInsulator Type: Projected\u003cbr\u003eNominal Gap: 0.060\"\u003cbr\u003e\u003cbr\u003eLower ignition system voltage requirements\u003cbr\u003eGreater ignitability and performance over conventional spark plugs\u003cbr\u003eIncreased fuel economy and lower emissions\u003cbr\u003eHighly durable against electrical and chemical wear\u003cbr\u003eGood performance spark plug\u003cbr\u003e45° V-Power center electrode\u003cbr\u003eManufactured using triple-gasket sealing process to prevent leakage through the shell\u003cbr\u003eAlumina silicate insulator for strength and optimal heat transfer\u003cbr\u003eSolid-copper core for a more powerful spark with less firing voltage\u003cbr\u003eCold-rolled threads for easier removal and installation\u003cbr\u003eCorrugated ribs eliminate misfire causing “flashover”\u003cbr\u003eTrivalent metal plating\u003cbr\u003eIncreased anti-fouling characteristics and performance\u003cbr\u003e\u003cbr\u003eDesigned to ignite the air\/fuel mixture within the combustion chamber, a spark plug has to withstand the high temperature and combustion pressure within the engine. If everything operates properly, the engine runs efficiently providing optimal performance, maximum fuel economy and the lowest exhaust emissions due to effective combustion. Spark plugs are available in different heat ranges and thread sizes to suit engine requirements. There are several factors - such as thread reach, thread diameter, the insulator nose projection and whether the spark plug incorporates a gasket or is of the conical type - to consider when choosing the correct spark plug for your needs.\u003cbr\u003e\u003cbr\u003eThe spark plugs also feature the alumina silicate insulator that is virtually pure to insure dielectric and physical strength, as well as heat transfer away from the tip for maximum performance. To eliminate “flash over,” which can cause misfiring, these products are built with corrugated ribs and feature cold-rolled threads to prevent damage to the cylinder head and make installation and removal easier. The products also feature trivalent metal plating for superior anti-corrosion and anti-seizing properties.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMfg Part No: 3951 TR55\u003c\/li\u003e\n\u003cli\u003eRelated Part No: 3951 TR55\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NGK","offers":[{"title":"1","offer_id":47985652924657,"sku":"NGK-TR55","price":8.38,"currency_code":"USD","in_stock":true},{"title":"4","offer_id":47985652957425,"sku":"NGK-3951-4K","price":16.29,"currency_code":"USD","in_stock":true},{"title":"6","offer_id":47985652990193,"sku":"NGK-3951-6K","price":22.06,"currency_code":"USD","in_stock":true},{"title":"8","offer_id":47985653022961,"sku":"NGK-3951-8K","price":30.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0779\/1326\/0273\/files\/3951_p01.jpg?v=1777316651","url":"https:\/\/allworldauto.com\/products\/ngk-spark-plug-p-n-tr55","provider":"All World Auto","version":"1.0","type":"link"}
