Mind the Gap When Changing Out Spark Plugs

You’ve heard of spark plug gaps, right? The manufacturer determines how much space there should be between the spark plug’s two electrodes. That determines how far the spark will jump, and how big a spark you get.

Most spark plug gaps are somewhere in the range of 1 to 1 1/2 millimeters. When we install spark plugs, we always check the gaps. Why? Well, some come out of the box perfect. But some don’t. Who knows why? .

The size of the gap is very important.

If the gap is too small, there’s not enough room for the spark to jump. So the spark won’t be big enough and hot enough to combust all the fuel and air coming into the cylinder when you rev up the engine.

Conversely, if the spark plug gaps are too big, the spark can get blown out at high speeds. The amount of air and turbulence in the cylinder increases as the speed of the engine increases. And if the gap is too wide, the spark will just get extinguished at high speeds.

You can buy a gaping tool at your local auto parts store. And then you’ll have a working car and a new hobby.
