Spark plug wires transfer the spark from the coil to the plugs. It can be a fiddly job, but it’s definitely worth doing if you think your spark plug isn’t working efficiently. You can use a feeler gauge or other measuring tools to do this.
Sometimes, spark plugs come ‘pre-gapped’, but it can be a good idea to check the gap yourself. If it’s not right, the engine may fail to start-up properly. Gapping refers to the process of making sure that the gap that the spark of electricity has to jump across is exactly the right measurement. 14mm – J, P, PQ, Q, QJ, K, KJ, PK, PT, S, SF, SK, SVK, T, W, TR.You will see the thread size denoted by letters: Spark plugs come in varying thread sizes – again, you’ll need to make sure you get the right size for your vehicle. If you’re looking at spark plugs, make sure you check the number to see what type you’re getting. Lower numbers mean a hotter type of spark plug, whereas a high number indicate a colder type. The heat rating of spark plugs is indicated by a number. Spark plugs vary in the amount of heat they dissipate. If a car has a high horsepower, it’s more likely to have a cold spark plug. Heat can be transferred out of the engine via the combustion chamber. They tend to last longer.Ĭold spark plugs are, as the name may suggest, a little cooler. This helps to burn off carbon deposits more efficiently. It has more insulation than a cold plug and is kept at a higher temperature. You can either get hot plugs or cold plugs. Hot Plugs and Cold Plugs – What’s the Difference? Washers – usually made from copper or steel.Ground Wire – usually made from the same material as the center spark plug wire.Center – Electrode – again, this must-have good conductivity.Insulator – this has good thermal conductivity.Spark plugs are made up of the following: Spark plugs are small and inexpensive and are made from different types of materials – which one is suitable for your vehicle will depend on a few different factors (which we will discuss later in this article). Diesel cars do not have spark plugs – they work slightly differently, using something known as a ‘glow plug’ instead. Most vehicles usually have one spark plug per cylinder – and most cars on the road will have four cylinders. ‘Thermal performance’ is the phrase used to describe how well the spark plug dissipates heat, and how well it holds the right temperature. The second function of the spark plug is to transfer heat away from the combustion chamber, another very important job. Everything about this process is timed to perfection.
So, without a spark plug, your car isn’t going anywhere.Īll of this happens in a few milliseconds – the piston that draws fuel and air in the cylinder will be at TDC (Top Dead Center) when the plug shoots out the small bolt of electricity. As soon as the engine’s pistons start moving, your car begins to power up. The electricity crosses a tiny gap, which starts the ignition for the combustion that your car needs to start up. Spark plugs give a tiny spark of electricity – the spark that will allow your car to start. You’ve probably heard of a spark plug, but do you know how it works?
