I seen on horsepower tv they used pulsestar plugs on a stock newer vette and it gained around 5 hp (i think) and probably better mpgs they claimed. I didn't know if they made them for our trucks and if any body has used them?

Or, what is a good replacement plug over the stockers?

 

The only plugs I'd put in a 5.4 3V are Motorcraft PZT14F's or Champion one piece. I do not believe there are Pulsestars for it.

 

They don't make it for the 5.4 3v. I started a thread about it 1 or 2 weeks ago.
