Unlike a coating, WPC is a surface enhancement that works to reduce friction and increase the strength of metal engine parts. This treatment can lead to improved engine performance and longevity.\n\nThis set of rocker arm shafts is compatible with a wide range of J Series engines, including those with the following engine codes: J30A1, J30A4, J30A5, J32A1, J32A2, J32A3, J35A3, J35A4, J35A5, J35A6, J35A8, J35A9, and the J37A1 (specifically for 08-09 models only).","brand":"P2R","offers":[{"title":"Default Title","offer_id":52663216144696,"sku":"WPC-14631-14632-8","price":375.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687522052.jpg?v=1784325000","url":"https:\/\/store.motormia.co\/products\/j-series-intake-rocker-arm-shafts","provider":"MOTORMIA","version":"1.0","type":"link"}
