{"product_id":"r7438-8-racing-spark-plug","title":"R7438-8 Racing Spark Plug","description":"The NGK R7438-8 Racing Spark Plug is engineered for extreme use and demanding race conditions, ensuring reliable ignition for tuned engines.\n\nThis plug is recommended for vehicles running Stage 1 software or beyond, where factory spark plugs may fail under increased stress. The R7438-8's one-step colder heat range (Heat Range 8) helps dissipate heat from the combustion chamber, reducing the risk of pre-ignition or detonation in highly tuned applications. Its construction includes a trivalent metal plating for anti-corrosion and anti-seizing, corrugated insulator ribs to prevent flashover, and a pure alumina silicate ceramic insulator for strength and heat transfer.\n\nInstallation requires careful attention: these plugs are pre-set from the factory with a delicate fine-wire iridium electrode and must not be re-gapped. They are sold individually, so ensure you purchase the correct quantity for your engine's cylinder count. The NGK R7438-8 is a popular choice for tuned VW, Audi, SEAT, and Skoda 2.0 TSI\/TFSI engines, among other turbocharged performance applications.","brand":"Racingline","offers":[{"title":"Default Title","offer_id":52872833597752,"sku":"NGK-R7438-8","price":41.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/r7438-8-racing-spark-plug","provider":"MOTORMIA","version":"1.0","type":"link"}
