How can I maximize fuel economy on my 08 Wrangler?
The intake and exhaust mods won’t hurt fuel economy just by installing them. However, I’ve noticed that when I drive cars after adding louder intakes/exhausts, I tend to drive them harder because I like the sound – therefore making my gas mileage worse. As far as what to do to maximize mileage, you COULD install a taller rear-end gear to lower your RPM when cruising, but it will definitely slow your Jeep’s acceleration as a side effect – and the new Jeeps aren’t real fast to begin with so I’d probably just live with the bad mileage because there’s not much else you can do. As far as adding some power goes you can always find supercharger kits out there, but be prepared to spend thousands of dollars to get one and install it.
