How do you use a spark plug indexing tool?

VIDEOClick to see full answer. Keeping this in consideration, does indexing spark plugs work?The mechanics behind indexing a set of plugs are quite simple. Verifying that the electrode gap of the spark plug is facing the air/fuel mixture allows the mixture to ignite more efficiently. Indexing plugs can only be achieved when a conventional-type “gapped” plug is the threaded into the head.Also, do you need to index spark plugs? Indexing spark plugs is a simple process. All you need is a spark plug socket, a ratchet, and some indexing washers. This specific spark plug socket is really helpful for Honda heads because it has a deep design, is magnetic, and can be marked to identify where the spark plug ground electrode is pointing. Furthermore, what is indexing a spark plug? Basically, indexing a car spark plug faces the open gap of the plug’s ground electrode toward the direction for the optimal burn of the fuel mix in an engine’s combustion chamber. Although technical experts often disagree as to the actual performance enhancement attained by indexing a car’s spark plugs, it can’t hurt.Is a bigger spark plug gap better?A wide gap creates a longer spark arc but without sufficient “juice” from your ignition system, (including amps), it can be weak and yellow in color. So a small intense spark is much better than a big, weak spark, especially when dealing with richer fuel mixtures and more volumes of fuel being burned.
