I want to keep my 2007 4.0 a street driver but i would also like to run high 13's low 14's and i want to know if NOS would be ok.
i have 3.73 gears with posi
steede cold air
flowmaster duals
shorty headers
sniper tuner
bosch +4 spark plugs
spark plug wires

 

best way to keep it streetable and be fast is of course nitrous. is the car auto or manual? go back to motorcraft plugs or get a colder ngk. i think most of the experienced nitrous guys would not be running bosch +4's, i would never use that plug in anything, personally.

 

NOS would be the least expensive way to do it. But you certainly can do it with a super/turbo charger kit and still be just as streetable.

 

It's an auto, why dont you suggest bosch

 

platuinums plugs do not work well at all imo either. i had bad issues w/ then on a NA '90 GT

stock coppers closed up a bit are nitrous friendly. and you'll need to lose the tune as well if your gonna spray more than 50. the kits are designed to use stock timing

 

i would ****can the bosch plugs and stick to either NGK or Autolite(motorcraft) and only use coppers with nitrous


platinums are bad with nitrous but i wouldn't put ANYTHING made by bosch into anything they're garbage

 

ok thanks for all the advice, but i got another question, would you use dry or a wet shot and how much?

 

I'm not sure there are any dry kits available for the 4.0. The ZEX wet kit is popular and with the 75hp jets are good for low 14's and high to mid 13's depending on your set up & driver skill. I went my best of 13.733 and only have stock gears. The 100hp jets should have a nitrous specific tune. With sticky tires mid 13's should not be a problem

 

Does the car run fine still? and how much did you pay for that?

yep, 71k daily driver.
About $450 I think. I traded parts & cash for a used V8 kit off the MF classifieds. ttle heater is a must so plan on another at some point for a DynoTunes heater.
