I have the 4.7L v8 in my truck, I put the drop in K&N air filter on my truck. I also installed the Airaid TB spacer as well on the same day. When you install these two products together, you can definitely feel the difference in acceleration, a lot quicker. My question is, what else can I do to get more power out of the truck and make it quicker, without voiding the factory warranty. I know there is the Jet Performance chip, anyone ever used this? My dodge dealer said I could install the chip without voiding the warranty, the only draw back is not knowing what kind of power I would get out of it and also having to use mid-grade gasoline. Also Gibson headers, the make a set to fit the
4.7L for my truck. Performance gains claim to be 15-20 HP, 26 FT LB/TQ. Has anyone installed the Gibson headers on the 4.7L? I read that installing headers on a vehicle will not void any factory warranty according to different websites, but I'm not sure. Thanks for any feedback.- posted
