What spark plug does a Honda GX690 take?

Does it matter which spark plug I buy?

While you should buy spark plugs in matching sets for your vehicle, not all spark plugs are universal. Spark plugs come in different sizes with different gaps and are manufactured using a variety of metals.

Does it matter what brand spark plug I use?

The engine won’t know the difference. All spark plug manufacturers cross-reference their plugs with other brands so their brand can be interchanged with other brands. For most applications, there are usually a variety of brands that are interchangeable.

Does NGK make Honda spark plugs?

Genuine Honda OEM Spark Plug 98079-55846 (NGK BPR5ES) Honda & other small engines.

What is Honda OEM spark plug?

Here’s how a standard OEM Honda plug is constructed: Platinum or Iridium Center Electrode. A OEM Honda plug will have a platinum (90k mile rating) or iridium tip (120k mile rating). These are both costly metals, but prolong the life of your plug.

How often should Honda spark plugs be changed?

To keep your Honda vehicle’s ignition system working its best, experts recommend changing your spark plugs about every 30,000 miles.

Which brand of spark plug is best?

What type of spark plug lasts the longest?

Platinum is much harder metal than nickel alloy and has a higher melting point. Since platinum is harder, it holds its sharp edge much longer than a conventional spark plug, up to 100,000 miles. Longevity is a key advantage of platinum spark plugs.

Do expensive spark plugs make a difference?

The most expensive type of spark plug is the iridium type. It is harder and more durable and generally lasts longer than platinum types. They have a smaller center electrode and fine wire centers which can generate current faster. It provides better power and complete combustion that leads to better engine performance.

Why are NGK spark plugs better?

NGK spark plugs feature trivalent plating. This silver or chrome-colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal.

What happens if you use a hotter spark plug?

Overheating will cause the electrodes to wear quickly and can lead to pre-ignition. Pre-ignition occurs when the air-fuel mixture is ignited by a hot object/area in the combustion chamber before the timed spark event occurs.

Should you lubricate spark plug threads?

Just about every spark plug manufacturer will recommend against putting any lubrication on spark plugs. NGK spark plugs, AC Delco, Champion, Bosch, Denso, and more all say to avoid it.

Will a hotter spark plug stop fouling?

Found in many passenger vehicles, hot spark plugs have more insulation to transfer the heat slowly, which keeps the temperature high enough to burn off carbon deposits and avoid premature fouling. This helps allow for more time between spark plug changes.

Is it better to do spark plugs hot or cold?

Start with a cold plug

“If it is too cold, the plug will eventually foul and misfire, and while this results in rough operation, it won’t hurt the engine.” Selecting too hot a plug can lead to preignition and detonation that can severely damage an engine.

What kills a spark plug?

If the tip temperature is higher than 850°C the spark plug will overheat which may cause the ceramic around the centre electrode to blister and the electrodes to melt.

Why are my spark plugs burning so fast?

Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail. In addition, if the cooling system isn’t functioning correctly, it can cause the engine and spark plugs to overheat. This overheating can lead to the spark plug’s electrode wearing out faster.

What does a black spark plug mean?

Black, dry soot on the electrodes and insulator tip indicates a carbon-fouled plug. This can be caused by a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture or idling your vehicle for too long.
