Do NGK plugs come gapped?

Although the NGK factory will set the gap to a preselected setting, this may not be the right gap for your particular engine. The incorrect plug gap for your engine can contribute to a high rate of misfires, loss of power, plug fouling, poor fuel economy and accelerated plug wear.

What is the difference between BR9ES and br9eya?

They are the same plug, except the YA means it has a V-grooved center electrode. The electrode has a small split on the end of it to help produce a better spark.

What is the difference between BR9ECS and BR9ECS 5?

the only difference between br9ecs and br9ecs5 is that the br9ecs5’s come pre-gapped from the factory. Absolutely identical spark plug, but the non “5” are left for you to gap.

What is the difference between BPR5ES and BPR6ES?

The BPR5ES have 5 stages in their heat range where the lower number in the range determines a hotter plug and the higher number in the range indicates cooler spark plugs. And the BPR6ES has six thermal ranges where the 6th number in the range is the coolest.

What happens if your spark plug gap is too big?

Excessive Spark Plug Gap The increased length of the spark travel weakens it, robbing it of the hot, strong ignition charge it needs to fire the plug. Excessive plug gap also results in cylinder misfiring, a possible no-start condition, wet, black or fouled plugs, engine hesitation and rough idle.

Why are there so many different spark plug gap firing configurations?

Sometimes customers wonder, why there is so many different spark plug gap firing configurations. The reason is, that in order to get the best possible performance, the spark plugs have to be carefully matched with the appropriate application and intended use.

What is the spark plug gap on a turbo car?

Some applications such as ProMod turbo cars using M1 fuel frequently run a spark plug gap as small as .012″, even though they are equipped with some of the highest output ignition systems providing in excess of 60,000 Volts high current and high mJ power output.

What is the smallest spark plug gap for high output ignition?

These guys, even with their custom high output ignition systems making upwards of 60,000 volts (high current & mJpower output) run a gap as small as .012. Copper VS. Iridium Plugs You aren’t the only one.

What is a spark plug gap gauge?

A spark plug gap gauge is a disc with a sloping edge, or with round wires of precise diameters. It is used to measure the length of the gap between the ground and central electrodes. The simplest gauges are a collection of keys of various thicknesses which match the desired gaps.
