1999-2004 Mustang V6 Performance Parts

While we all appreciate the 3.8L and 3.9L V6 engines of the 1999 to 2004 base model Mustang, they lack a little bit of the juice their big brother V8 offers. The exhaust note can also use a bit of work as well, depending on what you're going for. Fortunately, these are minor issues we can help you fix without much stress or time at the work bench. These OHV engines respond extremely well to even the most basic of cold air intakes or cat-back exhaust systems.
