Subarus do not have traditional spark plug wires. The ignition system in Subarus is designed with coil-on-plug technology, where each spark plug has its own ignition coil directly attached to it. This eliminates the need for spark plug wires, as the ignition coils are integrated into the engine wiring harness. Instead, the spark plugs are connected directly to the ignition coils.

What cars have spark plug wires?
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.
Do cars with coil packs have spark plug wires?
On modern cars with an electronic ignition system that uses a computer rather than a distributor to fire the spark plugs at the right time, the coil is likely to be mounted directly to the spark plug, or close by, without the need for high-voltage spark plug wires.
Why do Subarus sound like they are misfiring?
The 2.5-liter Subaru engine makes use of something called unequal length headers, which are exactly what they sound like. The header piping from cylinders one and three are of a different length than those from two and four.
Do cars still use spark plug wires?
Really old vehicles use a distributor, distributor cap, and spark plug wires. Some later models have an ignition system without a distributor but still have traditional spark plug wires. Newer vehicles use a coil-on-plug ignition system that eliminates electrical problems caused by worn-out spark plug wires.
What makes a Subaru misfire?
A misfire means that your engine isn’t running as efficiently as it should be: either there’s too much or too little fuel being injected into each cylinder, air is going into the wrong cylinders, or something is blocking the flow of exhaust gases out of the engine.
Why are Subaru spark plugs so expensive?
Because of the cost of iridium, the electrode is thinner, but they still deliver better power, better combustion and longer life than other plugs.
How long do Subaru spark plugs last?
Modern SUBARU BOXER® engines require improved spark plugs made with material like platinum. This means you’ll only have to worry about changing them every 60,000 miles or so.
Do new ignition systems have spark plug wires?
Newest type of ignition system. Very different from conventional and electronic – coils sit directly on top of the spark plugs, no spark plug wires, and the system is electronic.
Why do some cars not have spark plug wires?
A: Many newer vehicles do not have spark plug wires; they have “coil-on-plug” (COP) ignition systems. By eliminating the spark plug wires, your vehicle has a more reliable ignition system. The coil-on-plug system eliminates the need for high voltage spark plug wires that can cause ignition problems over time.
Do Subarus have ignition coils?
Being attuned to your Subaru’s sounds and movements will keep your vehicle performing as you expect for years to come, and one of the critical components demanding your attention is the ignition coil. This small device is the heart of your Subaru’s ignition system, supplying power to the spark plugs.
