Are Spark Plug Wires Interchangeable?
Afterwards miles of faithful service, spark plug wires wear out, burn or pause. Damaged or worn-out wires can either block the voltage to the ignition system or let it leak out, leaving the combustion chamber with a missing or weakened spark. And without the necessary fire to properly burn the air-fuel mixture, engine starting and performance issues begin to show up, including bad idle, misfires, and high fuel consumption, which tin can cause fifty-fifty more than damage.
That's why most vehicle manufacturers recommend replacing the spark plug wires every thirty,000 miles.
If your spark plug wires are worn out or damaged, don't wait. It could toll y'all much more after.
You Tin Virtually Likely Exercise It Yourself
Aye, you can alter spark plug wires at home. In spite of the horror stories you lot may take heard (mostly from shops in dire need of business) well-nigh engines blowing upward because of incorrectly installed spark plug wires, the majority of car owners tin supercede the wires in their own garage perfectly without fear of causing engine bug. This applied guide will show yous how.
With the coin you lot relieve, you can buy a quality prepare of spark plug wires and practice other machine maintenance projects. And on most vehicle models, you lot can complete this job with a minimum of tools in nigh an 60 minutes on a Sat morning.
And so permit's change those wires.
- Screwdrivers

Wires are not interchangeable. Every cylinder works in sync with a detail electrical connection on the benefactor cap or ignition coil, depending on your car model.
ane. Wait for the engine to cool. Information technology's hard to work around hot components, and you lot may end up with some skin burns.
2. Remove or move to the side whatever parts or components that might prevent you from reaching a plug wire similar the air cleaner duct, engine cover, or radiator fan shroud. Utilise a screwdriver, wrench, ratchet, and sockets as needed.
iii. Choose a spark plug wire on i cease of the engine. Take hold of the wire's kick with your hand—the spark plug end—and twist the boot from side to side as you pull it off the spark plug. If you can't accomplish the kick considering information technology's confined in a pocket-size space, use a pair of spark-plug wire pliers.
4. And so, unhook the wire from any clips that concord the wire in place.
5. Trace the wire towards the other terminate and disconnect information technology from the distributor or ignition whorl. At this end, some plug wires apply a jump clip to secure the kicking to the distributor or ignition roll. If so, y'all'll need to push button in the tangs to unhook the clips while pulling out the kick. Use a pair of needle-nose pliers, if necessary.
On some vehicle models, the ignition ringlet pack, which some plug wires connect to, is mounted between the engine and the firewall, making information technology difficult to reach from above the engine compartment.
To solve this problem, you'll need to elevator the front of the vehicle using a floor jack. Secure the vehicle using a couple of jack stands and block the rear wheels with a couple of wooden blocks. Set the emergency restriction. Put on your goggles and crawl under the vehicle. Then disconnect the spark plug wire.
NOTE: Sometimes, yous can't even attain a plug wire stop even from underneath. You may need to lower the engine a couple of inches or so to attain one, ii or more wires.
Disconnecting the motor mountain may requite you access to the wire. Support the engine using a floor jack, and use the jack to lower the engine just enough to reach the wire(s).
On some models, y'all need to remove important components like the intake plenum, the accelerator cable, and other parts that require careful guidance.
If you need assist moving the engine or removing some components, I recommend ownership the vehicle repair transmission for your particular car model and following the steps in it. Y'all can buy a relatively inexpensive Haynes aftermarket repair manual at most auto parts stores or online. Get the manual for your exact year and model.

seven. Afterwards you find the wire of the right length, connect the wire end that corresponds to the distributor or ignition coil starting time.
8. Route the wire following the same path equally the original wire and hook the wire to its corresponding routing clips — use the clips included with your new prepare, if whatever. These clips keep the wire abroad from other electric wires (to avoid voltage crossfire), moving components, and hot surfaces.
nine. Finally, press fit the boot end of the wire over the spark plug fitting until the kicking snaps in place. Yous should hear or feel the metal connector inside the rubber boot snap over the spark plug belfry end. If this wire connection is loose it will prevent voltage from reaching the spark plug.
10. After installing the wire, follow steps two through 10 to install the balance of the wires.
11. When you're finished replacing all the wires, lower your vehicle and reinstall any components you may have had to remove.
Modify spark plug wires at the interval recommended by your car manufacturer or equally needed. Plug wires wear out or get damaged over fourth dimension due to the high temperatures in which they operate. It doesn't take much oestrus to interfere with worn out wires in new ignition systems that demand precise electrical ability. Past replacing the wires yourself, yous're saving on machine shop service expenses, you're reducing fuel consumption, and you're preventing engine hesitation, misfires, hard starting and other engine functioning issues. And it simply takes you a few minutes in well-nigh cases.
