Spark plugs aren’t necessarily the first thing that comes to mind when considering aftermarket parts. A new set of wheels, control arms, and brake pads are considered essential upgrades by most Jeep owners. However, these plugs are essential to the functioning of any Jeep. You’ll have a very difficult time starting the engine and driving without a proper spark.
Due to this, the focus of today’s article is to provide you with information about the Best Spark Plugs for Jeep. To make navigation easier for you, I divided this post into five separate lists/comparison tables.
Select first the Jeep model, followed by the engine, and only then select an option. We will give you the best features, pros and cons, and expert recommendations to help you make your decision. This time we have sixteen plugs for you to evaluate. Please join me in seeing what the market has to offer.
Spark plugs made from copper are recommended for owners of older Jeep vehicles. This is because they employ low-voltage ignition and are not always compatible with modern plugs.
There’s good news – they’re affordable and perform well when the going gets tough. Iridium or platinum plugs, on the other hand, will greatly benefit modern Jeeps with advanced engines.
Our vehicles need spark plugs for a variety of reasons. Let’s find out why! A spark plug’s main purpose is to create an electric spark to ignite the concentrated air-fuel mixture within a combustion chamber.
There are other uses for spark plugs as well! They can measure the amount of ionization inside a cylinder. Sometimes, they are used in furnaces to ignite mixtures of combustible fuel and air.
A quick comparison of these spark plugs has already been done. Here are the detailed features and specifications of the plugs that can be used for Jeep.
NGK V-Power Spark Plugs
The NGK V-Power spark plug offers cost-effective performance for almost any automotive application.
This is one of the best spark plugs for jeeps since they require less voltage to ignite the mixture so that complete combustion can take place.
This Spark Plug is efficient because it has a V-Cut in the center electrode that produces a sufficient spark to improve ignition.
The cold-rolled threads prevent cylinder head damage, while the trivalent metal plate resists corrosion.
Other spark plugs have a copper-coated core, while NGK V-power has a solid copper core that reduces emissions and offers better heat transfer and conductivity.
Their performance is better than that of conventional ones because they were built according to OEM specifications. Additionally, the alumina silicate insulator provides high heat transfer.
Bosch Double Iridium OE Spark Plug
Spark plugs made from double iridium are designed to provide long life and high performance. Their pin-to-pin connection significantly reduces quenching.
The construction complies with OEM specifications to ensure maximum performance. Spark plugs from this manufacturer can also be installed in advanced-engine European and Asian vehicles, making them one of the best spark plugs for Jeep Cherokee as well as for 2002 Jeep Grand Cherokee.
With Bosch spark plugs, you’ll get a 4-times longer lifespan due to their double iridium firing pins and ground electrodes.
The 360-degree sweeping laser program maintains a secure bond to the metal; so that the central electrode doesn’t crack, which provides better durability and heat transfer.
Auto lite XP985-4PK Iridium XP Spark Plug
The Auto lite Iridium XP spark plug has a fine wire design and platinum side wire program for better reliability and better ignitability.
This spark plug measures 4.2 x 3.6 x 1.1 inches and is suitable for heavy performance engines. Despite their low cost and long lifespan, you can always count on them.
In most cases, the core electrode is 0.6 mm of fine wire made of iridium-enriched platinum alloy, allowing for proper ignition of fuel and better performance of the vehicle.
NGK (3459) ZFR5N V-Power Spark Plug
The NGK (3459) ZFR5N V-Power Spark Plug, approved by original equipment manufacturer (OEM), is a remarkable upgrade over typical spark plugs.
If you are considering getting an NGK spark plug, you should definitely get this model.
The unique V-groove in the central electrode sparks between the central electrode and the ground electrode, which is essential in igniting fuel.
A central electrode V-groove allows the flame to spread to more areas, increasing ignitability and allowing for a comfortable ride. After all, it is the Best Jeep Cherokee.
NGK (3459) ZFR5N V-Power Spark Plug is simple in design but built according to OEM specifications, so you can trust it to perform at its highest level.
This trivalent metal plate is resistant to corrosion and abrasion, providing durability and longevity.
The NGK (3459) ZFR5N V-Power Spark Plug reduces the voltage requirements for the ignition system and ensures longer engine life.
Champion Copper Plus Spark Plug
A Champion Copper Plus Spark Plug can be found in many applications for power equipment today. Nickel central electrodes with copper cores provide a lower operating temperature and a longer lifespan of 12,000 miles or 20,000 kilometers for the firing pins.
So, you will be able to travel unrestricted for at least two years. Your automotive, marine, and small engine vehicles will be able to use it. In addition, it is considered to be among the best spark plugs for Jeeps. Sometimes also used for non-automotive operations, such as gardening, lawns, and other equipment.
The Champion Copper Plus Spark Plug offers more efficient performance. A Protected Ultra seal is applied to the shell of the spark plug, increasing its corrosion resistance.
By combining the ground electrode (platinum) with the fine wire electrode (platinum) fitted with special heat-active material, the spark plug is able to easily reach optimal working temperatures and sustain them; thereby, improving vehicle efficiency. Therefore, you will have a smoother ride.
The SAE/ISO-compliant spark plugs, which measure 4 x 1 x 1 inches, provide superior performance. Likewise, they have patented a semiconductor resistor known as SAC-9 for final suppression.
