{"product_id":"3-5-inch-x-4-25-inch-aluminum-velocity-stacks","title":"3.5-Inch x 4.25-Inch Aluminum Velocity Stacks","description":"The EMPI 43-4415 aluminum velocity stacks are engineered to enhance your engine's performance by optimizing and maximizing airflow into the induction system. These components, also referred to as air horns, contribute to improved fuel stand-off as air enters the engine.\n\nConstructed from durable aluminum with a satin finish, each stack measures 3-1\/2 inches in height and has an overall diameter of 4-1\/4 inches. They feature a convenient slip-in fit for straightforward installation.\n\nThese velocity stacks are specifically designed for 40-44mm EMPI, Brosol, and Solex carburetors, but they are not compatible with models that feature electric chokes. Their universal slip-in fit allows them to work with both 40mm and 44mm carburetor sizes within these brands.","brand":"Solex","offers":[{"title":"Default Title","offer_id":52663717003576,"sku":"43-4415","price":49.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687679619.jpg?v=1784329129","url":"https:\/\/store.motormia.co\/products\/3-5-inch-x-4-25-inch-aluminum-velocity-stacks","provider":"MOTORMIA","version":"1.0","type":"link"}
