{"product_id":"air-boss-cr-intake-plenum","title":"Air-Boss CR Intake Plenum","description":"The Glacier Diesel Power Air-Boss CR Intake Plenum is engineered to significantly increase airflow to the rear cylinders (4, 5, and 6) of your 2003-2007 Dodge Ram 5.9L Cummins engine. This elevated plate design expands the plenum area by 30%, directly addressing the common issue of higher EGTs in the rear cylinders and the associated head gasket failures. By improving airflow to these starving cylinders, the Air-Boss plenum reduces EGTs and enables you to safely utilize higher fueling levels.\n\nThis kit is more than just a flat plate; it's a true elevated design that provides the largest possible flow increase short of a fully fabricated intake plenum. The Air-Boss plenum kit includes essential components such as the Air-Boss Intake Plenum Cover, factory gaskets for a proper seal, and shortened injector line retaining brackets to maintain the correct factory IC piping to intake manifold connection geometry. This ensures compatibility with all aftermarket intake manifolds and stock mounting hardware.\n\nGlacier Diesel Power offers different configurations for the grid heater. The standard kit includes a custom height grid heater delete block. For those in colder climates, an optional grid heater configuration is available. This option utilizes the factory grid heater and includes custom-length stainless steel studs to accommodate the increased plenum height. Both the heater and delete block options, or a package containing both, are available to suit your needs.\n\nNOTE: This product does NOT ship to California.","brand":"Glacier","offers":[{"title":"Default Title","offer_id":52688561897784,"sku":"0307-ABIP","price":299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663689510.webp?v=1784891048","url":"https:\/\/store.motormia.co\/products\/air-boss-cr-intake-plenum","provider":"MOTORMIA","version":"1.0","type":"link"}
