Most of the original carburetor specification cars are the same ignition coil as the original Chari, are not they?
Light tuning is in progress from a simple question: "I got the same IG despite the exhaust volume more than doubled?"
After purchase, if you compare easily with the spark plug tester, you got a spark that is about 1.5 times stronger than normal IG!
Also, it got to catch on in real runs.
If it is too strong IG, you need frequent maintenance including spark plugs, and I think that it is just good product with excellent cost performance for me!
