What to look for in a spark plug wire?
To make replacing your wires a simpler process, look for spark plug wires with numbers on them. This will help you determine where to attach them. These numbers signify the lengths of each of the wires in inches.
Can a bad spark plug be a good spark plug?
Good spark plugs vs bad spark plugs sometimes have some very clear visual telltale signs. However, a spark plug can come bad from the factory and by just looking visually at a spark plug you can’t know if it is working properly or not. Spark plugs typically are one of the cheapest, yet most important part of any gasoline engine.
When do you need to replace a spark plug?
1) A bad spark plug is quite often the main cause of poor engine performance. 2) Spark plugs are very inexpensive to replace. It’s the cheapest place to start. 3) If you haven’t changed your spark plugs in 2 years or more, your problem is likely to be a bad spark plug.
How big is an inductive spark plug wire?
Testing an almost brand new wire, these were replaced about 5000 kilometres ago. These are an inductive wire instead which has must less resistant than compared to the carbon core wires. This wire is about 2 feet long so we should be expecting about 1300 to 2500 ohms.
Do you know how to choose spark plug wires?
Even though spark plug wires are simple parts (there are absolutely no moving mechanical parts to them), there’s surprisingly little information on the Internet about choosing the right spark plug wires for a given application. We’ll aim to remedy that here by covering the basics of choosing high performance spark wires for your ride.
What’s the best spark plug for a performance engine?
To cut to the chase before getting into the details, the best advice for a performance street engine is to put the hottest plug in the engine that will survive. That sounds overly simplistic but it’s accurate. A plug needs sufficient heat to keep the center electrode mostly free of carbon deposits that can cause a misfire.
Which is the best spark plug for heat range?
The key to a heat range selection is related to selecting a plug that will efficiently burn-off carbon deposits from the center ceramic during normal use of the engine. So for a normal, street-driven engine, that 3924 recommendation is a great place to start.
What’s the difference between shallow and deeper spark plugs?
The shallow style shortens the heat path to the shell, making the spark plug operate as a colder plug compared to a deeper style where heat must travel further from the end of the plug to the shell. Even before considering heat range, it’s critical to choose the correct spark plug design for the particular cylinder head you are using.
