Hello!

I have a little question. I bought an Escort Cosworth with a modified HTT Engine, means bigger Turbo and approx 300 HP at 1,2 bar.
So my question is, what are you think is the best spark plug for this type of engine?

Regards
Florian

 

Standard Ford ones at that power, but change to colder ones if you upgrade any further.

 

Ah, Ok. Thank you. And the standard ones are the MOTORCRAFT AGPR 12PP ?
Electrode Gap?

 

Try 0.7mm at your power, should be fine.
