Tech Question - spark plugs

[Ronny]

what is the best spark plugs for a escort cosworth t35 350bhp (i m driving now denso ik 31 )

[Dave H]

Standard ford motorcraft agps 071c is my plug of choice

[James @ Auto Dynamix]

ik31 is too cold for that power, if you want to run Denso you be best off on ik27s.

[mark shead]

For upto 350 the denso ik24 best suited above that the 27 is best. You can run the 27 if you have normal usage but they are a little cold for shunting the car in and out of the garage multiple times with driving the car.
