Ford Mustang 64-04 NOS Big Shot Nitrous Kit. For street and street/strip applications there's nothing better than the popular "dry" 5.0 system from NOS. It's designed to introduce the nitrous (which makes the intake charge oxygen-rich) in the intake tract and obtains the required extra fuel from the EFI unit. This assures excellent atomization of the air/fuel mixture, and serves to eliminate the problems (like "puddling" of fuel) that occur with our competitor's "wet" systems for the 5.0.
