Spark Plugs and Ignition Coils
In my many years of working on Vehicles, we found that there is no magic in Spark plugs. With Plugs that have multiple electrodes, all those extra electrodes end up shrouding the spark and in my opinion do the exact opposite of the claims they make. The best plug for power or mileage would be a side or surface gap plug because the spark is almost completely unshrouded from any electrode. The power difference is minimal if any but some modified cars require a side gaped and indexed plug because of possible interference with the Dome on High compression pistons. I have used about every Spark plug known to man. At one time I owned an old Toyota pickup that I was trying to increase the power and mileage on and can tell you that none of them made a difference.
So that is my opinion on the ignition system. In theory, for the best performance and economy, use standard plugs that are side gaped and an aftermarket ignition box but chances are that you won't feel or see a difference in mileage or performance unless you have a heavily modified vehicle or your factory parts are in bad shape. Bottom line, keep your factory ignition parts in good shape and they will give you everything that you can hope for.
