What spark plugs
Looking for some advice on what spark plus will be best... My 4x4 sapphire cosworth spec
Stage 2 msd evolution chip
3 bar map sensor
T3 turbo
-31 actuator
803 greens
Group A air filter
Bosch 044 fuel pump
Msd fuel pump loom. 12v at pump
Fuel pressure set to 3.5bar vac off 3bar on
Boost set to 25psi peak holding 22psi. Still getting a cough and back fire under heavy load. So my next step is to try new plugs. I have tried 071c but the engine ran horribly gapped at 0.75. Not sure what plugs are in atm as a lad gave me them new. Platinums maybe. Anyone got a guide or a preference? Cheers
