In addition, Spectre velocity stacks also have a smooth funnel shaped inlet that reduces restriction and turbulence of incoming air.","brand":"Spectre","offers":[{"title":"Default Title","offer_id":45790242275639,"sku":"SPE9604","price":22.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0759\/9790\/5207\/products\/67de2fc1c4d058ed17ac57d8621c4dc4.jpg?v=1688748316","url":"https:\/\/shopcoyoteperformance.com\/products\/spectre-air-filter-inlet-adapter-velocity-stack-4in","provider":"CoyotePerformance","version":"1.0","type":"link"}
