Combustion chamber & twin plugs

Hi All,

I'm an alfa fan.

The 4 in line Alfa Romeo engine has had the option of twin plugs
in the hemmispherical head for over 26 years.  They give it about
15% more power and 15% more torque and the torque peak is real low
at 4000 RPM.  All the current 4 cyl alfas have twin spark only.

1970 cc with 110 kW/6200 RPM and 187 Nm/4000 RPM

Get you to accelerate real nice on a standard car.

Cheers
