Save Gas And Incerase Horsepower By Side Gapping Spark Plugs

Step 4 Before & After

Here are before and after photos of a non side gapped vs. sided gapped spark plug. With the side gapped plug the spark is now un-shrouded and is more exposed to the fuel/air mix. the flame created will now be able to spread faster resulting in a more efficient burn before the exhaust valve opens.

Advance the timing and have the thing ping its head off great. Duh

Won't they foul faster?

If this does in fact burn fuel more efficiently, I don't personally know, than theoretically... yes it should foul quicker. Fouling is a result of carbon deposits left from ignition, however you are also burning more fuel per stroke. Petrol engines are famously inefficient at fuel usage. A very large percentage, I don't have specs sorry : (, of gasoline is pushed out through the exhaust. That's why modern vehicles in the US are required to have Catalytic Converters; their purpose is to burn any unburned fuel and lower Carbon/Nitrogen emissions.

If you want the fuel to spark faster, advance the timing. Duh.
