2002 Grand Cherokee 4.7 liter H.O.
working on making a newly purchased 02' high output "mine". started with fixing leaks and sealing her up. now i am working souping her up. I want to change the spark plugs, the records that came with the vehicle don't show they have ever been changed. I am not sure what plug to go with I know it needs to be a platinum tipped plug. But there are so many out there, (e3, bosch platinum 4, etc...) help me out here. thanks.
any other gas saving, horse power grabbing, general upgrades are greatly appreciated.

This shows, among other things, the recommended plugs to use to prevent damaging this engine. >http://www.wjjeeps.com/engine.htm#GENERAL
This shows some '04 upgrades over the '02, and at the bottom it shows a K&N filter and fuel injection kit you can get. >http://www.wjjeeps.com/ho_engine.htm
