If you are a serious nitrous junkie on a tight budget we have what you have been waiting for! NX introduces MainLine Nitrous Systems. MainLine Systems benefit from the years of research and development that made Nitrous Express the leader in the nitrous world, but at a price even the most budget-restricted racer can afford. Just the basics, no frills, just rock solid performance at rock bottom prices. Jetting from 35-150HP. The ML3000 has no competition, it is the only low cost EFI system on the market. Guaranteed to produce 150WHP! Fits 2006 - 2004 Mustang GT and other 4.6 2 valve Fords.
