ignition coil wiring

[geezer101]

Personally I'd use a solid state/transformer type coil with NGK plugs. MSD/Accel coils are not only expensive but you hear that guys have had issues running them on truck ignition systems and distributors. I think it comes down to the load it puts on them. Bear in mind you need to keep the ballast resistor as part of the ignition or it'll bake something (might be a big part of the $$$ aftermarket coil fails...?) Do NOT use platinum or exotic plugs in an old Mitsubishi - it will cause running problems. Same with Motorcraft plugs (Mitsubishis seem to HATE them ) Your Mitsu may already have a 'T' type coil in it - just replace it with an OEM quality coil. Rule of thumb - coils usually last about 10 years before they start to break down and lose output (on a daily driver)

For a stock engine and tune - NGK BP5ES plugs. Maybe BP6ES if you are experimenting with timing advance and premium fuel and/or bolt on upgrades like a Weber, headers and a street cam.

Interesting, US-market trucks seem to specify the BPR6ES, which is the colder plug, probably related to US smog tuning.
