Most Jeep Wrangler owners love their vehicles. Whether you enjoy taking your off-road, love the classic looks, like to put the top down or anything else about the Wrangler, you likely want to keep it in good running shape. Part of your regular maintenance should be changing the spark plugs. However, a lot of car and truck owners are not sure what type of spark plugs they need to get.
Types of Spark Plugs
Before thinking about which spark plugs your Wrangler needs, it is helpful to understand the different types. They are primarily categorized by the material used in the electrode.
- Copper: These spark plugs feature a copper core and nickel alloy electrode. These relatively soft metals make this type of spark plug the shortest-living. However, it is ideal for the low-voltage systems found in older vehicles. Some performance cars use copper due to its high conductivity. Replacing your spark plugs is a great way to tune up your engine. Whether you have an older model or just want to keep your Wrangler in pristine condition, this is a relatively easy and worthwhile maintenance task.
- Platinum: These plugs use platinum for the electrode. This harder material increases the service life of the spark plugs significantly. However, it runs hotter due to electrical resistance. Typically, newer vehicles with electronic distributor-based ignitions use platinum.
- Iridium: This rare metal is even harder than platinum. These plugs last about 25% longer than platinum spark plugs. They also perform the best in extreme conditions. They are more expensive but the added cost is often worth it.
- Double Platinum/Double Iridium: Double platinum and double iridium spark plugs have two discs to allow bidirectional sparking. They last longer than their single counterparts. Double iridium spark plugs last the longest of all types, about four times longer than copper spark plugs.
Although some spark plugs offer better service life and performance characteristics than others, it is important to use the right kind. They are typically not interchangeable as most ignition systems are designed to use specific types of spark plugs.
A common error is to think that double platinum or double iridium are just upgraded versions of platinum or iridium respectively. This is not the case. Only use the spark plugs specified in your owner’s manual.
What Kind of Spark Plug Do I Need?
The type of spark plugs used by your Jeep Wrangler depends on which engine you have. Different generations and even different trim levels may use different types. Consult your owner’s manual to check which type you need.
You can also use a VIN lookup free tool at your favorite auto parts store. This will check your vehicle’s identification number and determine which are the right spark plugs for you. Alternatively, many auto stores let you search by year, model and engine type. If you can’t find your manual, these tools will help you identify the correct spark plugs. this type of spark plug the shortest-living.
