Figured I would ask the experts.
What is the difference between a 2001 3.0L and a 2001 3.0L flex fuel. I know that the flex fuel engine allows you to run ethanol mixture but what was changed to allow it to do so.
The reason I'm asking is I have the flex fuel engine and I am getting ready to do some work on the engine as far as getting more performance. Adding under drive unit, Screamin Demon coil pack, K&N intake with larger MAF, Roller rockers, flowmaster cat back system and looking at performance chips also and I wanted to make sure I get the right stuff and some of it does not specify whether it will work with flex fuel engines or not.
