Hi, my daytona charger is only getting 14 city mpg and 19highway mpg. I am unhappy with this, so u guys have any performance parts I can buy that will increase mpg? how much would it cost and what should I gain from it? Don't think exhaust will help b/c daytona models already have high-flow muflers. Also, What reduction is easy on our chargers and how much weight would it remove? I was thinking spare and jack removal. Maybe carbon fiber parts too but not sure how much they cost or where to get them?
Thanx ahead.

Hi Mango19,
Welcome to the forum! It's fun in here....!
I have a 2006 Daytona and had a Jet 2 chip and K&N series 63 ram air and got 25+ MPG on a trip to CA from MN (4,000 miles) with three big guys, a trunk full of luggage and the A/C on most the time, at 75 MPH. Now I have the Superchips and get 23+ MPG at 75 MPH. I get better at 65 -- I think 65 is the optimum speed with a stock set up.
First things first: usually high-performance parts do not ADD mileage. Usually the MPG stuff is just being easy on the accelerator, a clean air cleaner, running at least 89 octane in your Hemi, having proper air pressure in the tires and drive with your windows up. Most guys here have discussed Tornado air swirlers for MPG, or additives, but don't spend any money with these. The exhaust is pretty good on the Daytonas, especially reducing drone when the engine is in MDS (4 cylinder) mode. Weight reduction isn't much in these monsters anyway -- they aren't dragsters but remember a general rule is 100 pounds is a .10 of a second at the track. Spare a jack removal is OK, but not when you need them on the road. Carbon fiber parts are expensive, and you need lots of it to make the difference.
For the quick HP and fastest change in the car, most have said N2O. It's the biggest bang for the buck. Zex has a kit especially for the Charger.
Post up some photos when you can!

Thanx for the help, I here CAI increase mpg, by how much if this is true? Does Mopar's CAI increase mpg b/c that's the only one that dodge will install for me so my warranty is still intact and how much hp u think I can get from the CAI? How much weight do u think I will lose with the spare and jack removal also?

Hello fellow Mango and welcome to the forum!
As you probably know the stock CAI, exhaust and slightly different PCM is what gives the Daytona a 10HP rated edge over the regular R/T.
If your car is stock a CAI isn’t going to get you much neither HP nor MPG, it’s isn’t going to hurt anything but the gains will be marginal. In the long run if you pump her up with headers/cam/tuning… it will make a bigger difference.
Oh, the spare/jack will shead roughly 40lbs. I've never took time to weigh them but for various reasons I've pulled them fro the trunk several times, so that's my guess. Some have also removed the rear seat to lighten the load at the track.
Don't remove the spare in lieu of fix-a-flat or something like that. That stuff will mess up the tire sensor located inside the wheel.
