Intake, Exhaust, and a Fastman throttle body.
a few stickers on the window should add a few hp as well

 

superchips makes one for your truck,i have one in my 02 4.7

 

If they do then their web site does no advertise it. They only have an option for a 2004 engine as the Hemi.



As far asa recharge kit I would just hit your local auto parts store and ask for a K&N recharge kit, they will know exactly what you need. The kit itself will run about $15 and once cleaned/oiled you will not need to do anything to your air filter for another 50k miles.

Fuel injector cleaner, I really don't have a preference. Look at the labels and see which one looks like it will suit your needs. If you are in a rainy area you might want to think about one that has a moisture remover for your fuel tank as well.

I am a big believer in synthetic oil. Most professionals will also agree on synthetic oil too. If the dealer just changed your oil I would wait until you hit 3k miles. Check is your diff oil, tranny and transfer case oil was changed. Ask about your radiator and when it was flushed. I know most reputable dealers will add the window dressing to make the vehicle better to get a better sale.

 

2002 is the only year they made it for the 4.7

 

You want to increase your mileage, get it breathing better. I see by your sig that you already have a flowmaster (not the best flowing muffler, but I wouldn't ditch it till it goes on you), so CAI would be next, then possibly headers. E-fan also helped me by a good 1-2 mpg. The jury is out on Throttle Body Spacers, some swear by them, some say they don't do a damn thing. I know the consensus on the Hemi is they only make a whistling noise, no gains. I do however, read more positive posts re: the 4.7.

 

HansonHVAC, first off, i would like to give you compliments on your wife, whose picture you have as your avatar.
Secondly, let me ask you this, because you seem to be very knowledgable on these things.
Does Mopar have a synthetic transmission fluid? And if not, does Amsoil carry one that's compatible?

 

Yes you can get Mopar transmission fluid at any dodge dealer. Personally i'd suggest amsoil though. I have nothing personal against mopars fluid but i just prefer amsoil in whatever i can get it. Its never let me down and seems to hold up much longer than any other i've tried. heres a link..

What about mobil synthetic is it anygood?

 

yeah mobil 1 makes a very good product also as does royal purple. Amsoil is simply my personal preference. Jesus i wish i could get paid for advertising for them!!! Seems like a promote their product on a daily basis!
