Will any spark plug work?

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. Finding the ones that you need can be difficult.

What happens if you fit the wrong spark plugs?

It’s actually very easy if someone has fitted plugs that are too long, the threads in the combustion chamber get carboned up, then tear the threads out as the plugs are removed with great difficulty. It’s very hard to damage the thread while unscrewing spark plugs, or anything else.

Do expensive spark plugs make a difference?

This would be more accurately described as “less performance loss.” Spark plugs do not increase the performance of an engine — even spark plug manufacturers are fairly forthright about that. … They won’t make the engine perform better than it did when it was new, but they will help it stay at that level longer.

Are spark plugs a standard size?

Most people use 3/8 for servicing spark plugs, so most spark plug sockets are 3/8 drive. There are 1/2 drive spark plug sockets, but it is unlikely that is an issue. I have never heard of a 3/8 size spark plug. Most spark plugs require a 5/8″ (16mm) size spark plug socket.

Does spark plug size matter?

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. Ensure the spark plug has the correct projection dimensions.

Are all spark plugs the same?

But not all spark plugs are the same. There are several different types on the market, and you’ll need to ensure that you’re getting the right type. Additionally, your vehicle might have more than one spark plug per cylinder (some high-performance engines have two).

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.

How do I know what spark plugs I need?

If you don’t have an owner’s manual, or if yours lacks the necessary information, you can find the correct spark plugs and spark plug gap in a general “Tune-Up Specification Guide” (called a “spec sheet,” for short) at an auto supply store.

What is the most common spark plug socket size?

What’s 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.

How many different sizes of spark plugs are there?

Spark Plug Guide – from Cyclepedia There are currently three spark plug thread diameter and pitch sizes used on motorcycles and ATVs: 10 mm x 1.0, 12 mm x 1.25 and 14 mm x 1.25. There are currently two thread reaches (lengths) used: 1/2 inch and 3/4 inch. Never use a spark plug of the wrong reach.
