Could anyone recommend a suitable NGK spark plug for the following spec supercharged 1275 engine please ? I've guessing as this is tuned and runs hotter that a cooler plug is needed ?
1275cc engine suck through m45 supercharger set up with hif 44 carb
- Aldon electronic Ignitor fitted inside my old 59D distributor body.
- Running with a Aldon amethyst mapping unit.
The car runs but seems to take a some time to fire or doesn't on the first try like the spark is weak and I feel the current NGK BR7ES might not be suitable ?
I've installed a brand new starter motor and coil etc when building the engine so can't see any of these being an issue.
