I have a 2004 ram 1500 5.7 hemi sport. I am looking to upgrade spark plugs and wires, air intake and performance chip. any suggestions or experience of what works the best?
Go with a stock spec plug unless you've done a lot of work to the engine. Wire should be an 8mm I believe, that are shielded.
Intake? Check out airflow innovations BFI for the HEMI. It's a nice intake!
Performance chip? Try a programmer, instead. The DiabloSport Predator is the best one out there for the HEMI, in my humble opinion. I have a lot of experience with these, over at the 300CForumZ, and have one on my SRT8. This unit will definitely wake up the HEMI.
Do you have an exhaust system on it yet? The three basic, best bang for the buck, mods for the HEMI are an intake, exhaust and the Predator.
I have installed Taylor wires and Bosch platinum plugs- I may be incorrect but I don't believe Diablo supports 05 and earlier Hemi's I purchaced a SC Cortex, I would be happier with a Diablo because they will allow custom tunes. I hope this helps there is alot of useful information on this forum.
