Does Length Of Spark Plug Matter? No, the length of sparkplug wire does not matter. However, The engine will not operate properly without the proper thread reach. If a spark plug with the wrong thread length is erroneously used, the piston or valve could strike it and damage the engine.
What happens if you use a shorter spark plug? If a spark plug is too long, it can protrude into the combustion chamber and hit the piston or a valve. A spark plug that is too short will cause your engine to buck. The spark won’t ignite your fuel correctly and can cause poor gas mileage, plus prompt your check engine lights.
Can I use longer spark plugs? Most spark plugs have a factory service interval of 100,000 miles, though some may be as much as 120,000 miles. Long-life platinum and iridium spark plugs will typically last up to 100,000 miles or longer provided the engine isn’t using oil or doesn’t spend a lot of time idling.
Are all spark plugs the same length? Not all plugs are the same size. There are the common spark plug sockets used with a common-sized spark plug socket wrench which are very popular and used in many different types of cars. But you cannot be really sure that your vehicle uses these. Spark plug sockets come in two sizes: 5/8 inches and 13/16 inches.

What’s the difference between long and short spark plugs?
The main difference between the two types is the reach of the threaded section into the combustion chamber. Single Platinum Spark Plugs. Larger engines generally use long reach plugs while smaller plugs use short reach plugs.
Do spark plug gaps increase over time?
Over time, the gap between the electrodes grows larger. As this gap increases, more electricity is needed to spark ignition of the air/fuel mixture. Eventually, the gap will grow so large that the spark plug won’t arc at all.
What happens if spark plug gap is too big?
One of the key factors that makes a spark plug work well, or not, is the size of the gap between the electrodes. However, if the spark plug gap is too large, the spark is unlikely to consistently “jump” across the long distance between electrodes, thus leading to a rough-running engine or one that doesn’t run at all.
Do I need a hotter or colder spark plug?
A colder heat range spark plug may be necessary if the ignition timing has been advanced to near the knock level. Higher cylinder temperatures near the knock level will bring the spark plug firing end temperature closer to the pre-ignition range.
How do I know if my spark plugs need changing?
What symptoms may indicate my vehicle’s spark plugs need replacing
Do spark plugs go bad after sitting?
Under normal conditions, a spark plug can sit in a vehicle for years without going bad, even if you didn’t ignite it once during that period. If stored properly brand-new, it can virtually sit forever. If you are unsure if your spark plug is causing you problems and should you replace it, you’re in the right place.
How are spark plug sizes determined?
The thread size for Spark Plugs refers to the size of the threads that screw into the cylinder head. The first number is the diameter. The second number is the thread pitch.
Can I use a shorter spark plug?
you want to use a spark plug with the same reach, shorter is safer than longer as longer could hit the piston, but shorter means it could work less efficiently since the spark could be ‘hidden’ up inside the threaded hole. Yes there are different plugs for different engines.
What does a bad spark plug look like lawn mower?
Its center electrode should have a flat top. If its top is rounded, then the spark plug must be replaced. Look for cracks or chips in the spark plug’s porcelain sheath as well as pitting on its firing electrode.
Do spark plug brands matter?
Yes, the brand matters when it comes to performance and how long they last. No. All spark plugs are made same, whether they’re cheapest or the most expensive ones. The most important detail in a spark plug is matching your engine’s design.
What is the best type of spark plug?
Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
Do spark plugs increase horsepower?
In short, yes, in some situations spark plugs can increase horsepower. The theory behind spark plugs increasing horsepower is that by providing more spark to the firing tip of the spark plug, it will (and does) combust more fuel.
Can spark plug gaps backfire?
The incorrect spark plug gaps can cause uneven firing of individual spark plugs and delay engine combustion; both of which can cause an engine to miss or idle erratically.
Is a wider spark plug gap better?
The larger the gap, the more voltage is needed to jump the gap. Most experienced tuners know that increasing the gap size increases the spark area exposed to the air-fuel mixture, which maximizes burn efficiency. For this reason, most racers add high-energy ignition systems.
What is the recommended spark plug gap?
Finding the Proper Gap Setting
How do I know if my spark plug gap is too big?
A list of some of the most common symptoms of incorrectly gapped spark plugs is laid out below.
Rough Engine Idle. An engine that has a rough, irregular engine idle is often due to spark plugs that are incorrectly gapped.
Engine Hesitation.
Engine Missing.
Poor Engine Performance.
Engine Knocking.
