Hey Jim, I got this one.

The stuff that you listed for your jeep will do absolutely no good. How can all this stuff save you money if you have to now use mid range gas at on average $0.10 per gallon more.

If it takes you 15 gallons to fill up and you fill up once a week, that is 1.50 per week, plus the cost of the add ons.

How much gas does it save vs how much has this cost you?

Now, if you were building a motor that would run above 4000 RPM, I would say go for it, but let's face it. The motors in our jeeps spend most of the time below 3000 RPM.

Big Jim said it best when he said if you see a dead dog on the side of the road and you have to get rid of some money, lift the tail of the dog and stuff away. You will get about the same bang for the buck.
