The copper core center electrode improves thermal conductivity, helping to dissipate heat efficiently. The ground electrode is nickel-based with a titanium enhanced twin-tip design, providing a stable and reliable spark path. The pre-gap size is set at 1.0 mm, optimized for precise ignition timing. The flat seat design ensures proper sealing in compatible engines, while the 19 mm reach and 14 mm thread diameter match OEM specifications for many Acura, Honda, and Toyota models.\u003c\/p\u003e\u003ch2\u003eAbout the Platinum TT Product Line\u003c\/h2\u003e\u003cp\u003eThe Denso Platinum TT line focuses on secondary ignition components that combine platinum and titanium materials to enhance spark plug longevity and ignition stability. The twin-tip ground electrode design reduces quenching and improves ignitability, making it suitable for vehicles requiring consistent performance under varied driving conditions. This product line is engineered to meet or exceed OEM standards for fit and function.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cp\u003eThis spark plug 4508 is compatible with a broad range of makes and models, including Acura Integra, Honda Civic, Toyota Camry, Volkswagen Golf, and others.

Use a torque wrench to tighten the spark plug to manufacturer specifications, typically around 18-22 ft-lbs, to avoid over-tightening. Verify the pre-gap size of 1.0 mm before installation, adjusting if necessary to match vehicle requirements. The 16 mm hex size allows for standard spark plug sockets. Always inspect the spark plug threads and seat for cleanliness to ensure proper sealing.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDenso spark plugs are manufactured to meet strict quality standards, ensuring reliable performance and durability. The Platinum TT spark plug 4508 undergoes rigorous testing for heat range accuracy, electrode wear, and electrical resistance. While specific warranty details may vary, Denso products typically come with a limited warranty against manufacturing defects when installed according to guidelines.\u003c\/p\u003e","brand":"Denso","offers":[{"title":"Default Title","offer_id":43446374957237,"sku":"BBNF-4508","price":12.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/NP_4508_Fro_216fd589-d280-4683-83b5-97e0b9ce823e.jpg?v=1774734436","url":"https:\/\/www.partcatalog.com\/products\/denso-4508-spark-plug","provider":"PartCatalog","version":"1.0","type":"link"}
