Denso Iridium / DenseCharger Cold Air/ X pipe for 360R?!

[White360R]

What are the best spark plugs I can buy for my Roush 360R?

Im going to get Cold Air INduction and eventually an X Pipe w/ Cats, but before I do I really want to get new spark plugs. My friend Gabe ( mingreystage2 ) says that Denso Iridiums are the best spark plugs I can get, and they should give me a strong 10+ horsepower with the supercharged engine..

Any other words of advice?

Im looking to do these small mods.. the Cold Air is coming first, then the plugs.. and eventually the X Pipe w/ Cats...

I dont need a short shifter IMO, because the T 3650 Tranny feels much firmer stock than my T 45 used to...

What do you guys suggest I get?

Hey Ryan... in your other post some guy said that new spark plugs void your warranty... Call Tom or Don at the dealership and ask them.. In October 2001 of MM&FF, they did a test with the Denso Iridiums and found that they pretty much eliminate misfires on boosted engines and added up to 30hp on a supercharged 5.4L Excursion engine.

Check your warranty.

Yeah I checked.. spark plugs void my warranty..

Im fine without doing it.. Ive pretty much decided to wait until I can get the computer upgrade from Roush ( the 380R one ) and then after that, I should have enough free cash for the FR 500 exhaust...

maybe then I can start to claim my roush gets 400/400, and not 360/375!!
