Well I submitted a thread about a month ago stating I had bought a powerdyne supercharger. I have since sold the powerdyne to aquire a new Vortech!! So I am reading the instructions and it says to replace the stock plugs with stock plugs? I am currently running Gibson exhaust abd will get a superchip burned shortly but I am thinking that stock plugs? maybe not. Thanks for any help I am new to Superchargers but cant wait to be blown!

 

I don't know about the Vortech but with the ATI it is recommended that you go to a plug that is one step cooler, staying with Motorcraft brand is OK.

 

Any more ideas? All help appreciated.

 

I was just reading some past threads and was planning that route. Thanks for the info.

 

I couldn't find the Motorcraft ones, so I went with NGK. Supposedly it's the same plug. They worked great with my Magnacharger.

 

You actually want 22c not 32 c

If you go NGK go with tr5 unless you plan on running more than 9psi...then you will want to use the tr6

Personally I run the NGK

The Motorcraft plug will last longer and give the same performance as the NGK, however I do alot of testing and hard running and the NGK will melt the grounding strap before it hurts the motor.

 

Well the plug change is done and what a bit*h!!!! I found the old plugs to be badly worn and the gap to be around 45 instead of 37!!!! I also found that the coolant line going from the intake to the heater core had been leaking into the passenger rear plug hole for a while. That mad for a fun time getting it out. All in all with everything done I am amazed at how much better it runs and better fuel mileage to boot.
I just wanted to share much "plug changing" experience. Thanks for all the inpout I'll let you know how the supercharger install goes next week!
