{"product_id":"laser-iridium-spark-plug-set-2","title":"Laser Iridium Spark Plug Set","description":"The Weistec Spark Plug Set is a direct replacement for M157 and M278 engines, designed for both high-power applications and factory replacement. These NGK laser iridium spark plugs are engineered to address the limitations of factory plugs, which may struggle with the high cylinder pressures of the M157 engine, potentially leading to misfire problems even in stock vehicles.\n\nThese spark plugs are one step colder than stock, a crucial feature for preventing pre-ignition in engines that have been modified to produce more power. This allows enthusiasts to push their vehicle's performance envelope further. The set includes 8 spark plugs, manufactured with a 12.0 mm thread diameter, 26.5 mm thread length, and a 1 mm electrode gap.\n\nKey features include higher output for high boost applications, a colder range for improved performance with increased horsepower, and a direct bolt-in design for M157\/M278 engines. They are suitable for all M157\/M278 vehicles, from stock to highly modified. It is important to check and set the spark plug gap before installation.","brand":"Weistec","offers":[{"title":"Default Title","offer_id":52866625798456,"sku":"01-157-00727-0","price":199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687409787.jpg?v=1787909386","url":"https:\/\/store.motormia.co\/products\/laser-iridium-spark-plug-set-2","provider":"MOTORMIA","version":"1.0","type":"link"}
