This is an informative explanation of different coil systems, clearly explained.

only found one error he said more emissions but he did mean to say less emissions.

I thought a few people in motoring might find it interesting and informative. I did once he got onto the advantages of newer types.

As you can see the problem is . most people dont want to learn they want to stay in there dreamworld . And only look and watch if they have to move 2 fingers to fix a problem. Hoping that somone or something is telling them the silver bullet fix on how to make there car in to a perpetual motion devise.
While your thread is of interest to people who actuarly watch stuff i post this on here also as its pointless to make a new thread that also almost no one reads.
These articles are often over 95% accurate.

Fortunately I have the coil on plug system. It is very reliable.
It has only two wires to each coil, but I see later engines have four wires. I wonder how that makes them better.

2 wire coils are usually igniter inside the ecm or external 3 or 4 wire coils have igniter inside coil more reliable imo. The fourth wire is usually a feedback wire most manufacturers have shifted away from the feedback system and will use crank speed variance for misfire detection
