We cut off the side electrode and get more stable engine operation

The stability of the engine largely depends on the spark plugs. At such high speeds, even a slight delay in the spark breaking is accompanied by a loss of power. By modifying the spark plugs in this way, you will eliminate misfires and the engine will work like a clock.

Required Tool:

hacksaw for metal;
file;
dipstick

The process of refining spark plugs

Before modification, if the spark plugs are not new, they need to be cleaned. Dimexide dissolves coking well, and orthophosphoric acid removes deposits from additives on the central insulator.

The side electrode of the spark plugs is shortened. As a result, the spark jumps not along the axis of the candle, but perpendicular to it, which changes the flame front.

After trimming, a gap of 1 mm is set on the spark plugs. You can chamfer the central electrode with a drill, but this is not necessary. After this modification, the car will start easier, and the twitching when cold will disappear. Please note that this upgrade does not apply to iridium and platinum spark plugs.
