How long do Toyota spark plug wires last?

around 60,000 to 70,000 miles
A quality set of spark plug wires can generally last around 60,000 to 70,000 miles. Again, it is a good idea to replace these parts prior to a failure, like a misfire.

What size spark plug wires should I use?

Most manufacturers recommend an 8 or 8.5mm plug wire on most applications. Exceptions would be an all-out race car or a street rod where EMI/RFI suppression is not a concern, but weight and appearance are. In which case, a 5 or 7mm wire might be a better option.

What are the wires to the spark plug?

Spark plug wires, also known as ignition cables, are a key part of the ignition system. Car engines that have a distributor or remote coil pack have spark plug wires that transfer the spark from the coil to the spark plug.

Does changing spark plug wires improve performance?

The short answer is Yes, when you replace the spark plugs and wires can increase your vehicle’s performance. New spark plugs help keep your engine at its peak performance and efficiency levels. Of course, every vehicle on the road will misfire from time to time.

Should you replace spark plug wires when you replace the plugs?

If your vehicle has spark plug wires, most owner’s manuals recommend that the wires be replaced at the same time as the spark plugs, so you’ll probably want to have both new plugs (the correct ones for your vehicle) and new wires on hand before you start the job.

What happens if you mix up spark plug wires?

Screwing up the plug wire order would cause cylinder misfires, and the unburned fuel usually flow out to exhaust and potentially damage the O2 sensors and Cat – but should not happen with only few seconds of cranking the engine.

Can you mix and match spark plug wires?

Can You Mix And Match Spark Plug Wires? In addition to matching cable length, you must not mix up the order of the spark plug wires. It is possible for these wires to malfunction or cause the cylinder to misfire, causing drivability issues and possibly severe engine damage.

How do I know if I need new spark plug wires?

With the engine running, move the test light along the length of each spark plug wire. If a spark jumps from a plug wire to the test light at any point, this is an indication that the insulation has broken down, and the spark plug wire should be replaced.
