A bit of advice here..stay away from a resistor plug on the Alfa as it will contribute in weakening the spark dramatically.drivers71 wrote:One more thing Kevin - What spark plugs do you use in your 3 litre GTV6 cars?
Previously I always used Golden Lodge 2HL plugs in my 2.5 cars, but this 3 litre arrived with NKG R BPR6EY plugs. I don't have any Lodge plugs on hand, and they seem difficult to get hold of now - I think they are now part of Magneti Marelli, but they don't list any. Do you know of any suitable alternatives please?
Unless you have got rid of the suppressors and replaced the solid wires with a carbon type wire, it will just not work.
This may be a contributing factor to the rough running below 3000 rpm. Any plug with the "R" designation is a resistor plug.
