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.\u003c\/p\u003e\u003cp\u003eNitrous System with Billet LT4 Supercharger Lid w\/ 15lb Bottle.\u003c\/p\u003e\u003cp\u003eThis product may expose you to chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.\u003c\/p\u003e","brand":"Nitrous Express","offers":[{"title":"Default Title","offer_id":51779938025784,"sku":"N004 20939-15","price":3363.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/horsepower-asset-242342-5208895-square.webp?v=1779218543","url":"https:\/\/store.motormia.co\/products\/nitrous-express-nitrous-system-with-billet-lt4-supercharger-lid-w-15lb-bottle-20939-15","provider":"MOTORMIA","version":"1.0","type":"link"}
