Nitrous and fuel are injected into each cylinder from inside of the supercharger lid, providing direct port style distribution. Systems come standard as a single stage with jetting for 100 to 300WHP. This lid is made from a solid piece of billet aluminum with 1\/8NPT machined directly into the lid, which makes it easy to add a direct port water\/methanol later on.","brand":"Nitrous Express","offers":[{"title":"Default Title","offer_id":51099360690491,"sku":"BKIR_20939-12","price":5166.4,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/5958\/2011\/files\/20939-12_l.jpg?v=1775410547","url":"https:\/\/performancepartscanada.ca\/products\/nitrous-system-with-billet-lt4-supercharger-lid-w-12lb-bottle","provider":"Performance Parts Canada","version":"1.0","type":"link"}
