I have a 2006 Mustang
GT which I installed a Roush supercharger kit in a few years ago and have been very satisfied.
The kit came with Autolite HT 0 spark plugs. I set aside and saved the original spark plugs that the motor came with which are Motorcraft PZT1F.
My question is can I install the PZT1F plugs and run them?
I realize the HT 0 plugs are designed for motors with boost, but I find that Im not using the boost very much in a while, and the HT 0 plugs I have in the car right now dont seem to have much electrode left on them, quite a wide gap, perhaps worn out as I have 69000 miles now.
I have heard that Roush might have a reason for the HT 0 only because of programing on the ECU.
Can I swap in the Motorcraft plugs and still be good to go for around town driving?
