I had no change in mileage, but it's all in how you drive it. If I'm nice I'll get 14 city and highway, which is exactly where I was before the Radix. It's hard to keep your foot out of it though. Generally I'm around 12.5 - 13.

The Radix will do well on it's own, but will do awesome with the other mods too. I kind of did my setup backwards, put the Radix on before anything else. Then I got exhaust, then headers. If you only have so much to spend, the Radix would be a great start, then you could come back and fill in the holes later.

 

i would think that a cam would do a lot to wake that motor up.

 

Radix firsst then go from there I would probably go that route.
