If you turn on your ignition every morning, you probably do not think about what is happening under the hood-it takes a lot of parts to work together to get the engine to start, and each one needs to function in harmony to keep the motor going. However, it is still a small and powerful device that has the capacity to initiate the process.
An internal combustion engine, a gasoline-powered device powered by internal combustion, relies on the spark plug to deliver the electric current. Spark plugs are very important, as they can make a remarkable difference to the performance of a car’s engine.
You don’t think twice when you turn on your ignition every morning, but you might not realize how many parts work together to allow you to start your car. Each one must work harmoniously in order for you to get started, and each one must function harmoniously simultaneously. Although it is not very powerful at all, the device has the capability of initiating the process if it is given full power.
List of Best Spark Plugs For Toyota 4Runner
Bosch Iridium Spark Plug 9609
Iridium fine wire according to Bosch OE. There is no such thing as one size fits all for iridium plugs. Give your customers a product that will last a long time and give them high performance at the same time. Ignitability and performance are delivered to an unprecedented level with the ultra fine electrode design and laser welded, tapered ground electrode. A laser-welded ground electrode with a special inlay of iridium alloy and the iridium-alloy center electrode help to make it go the distance.
- Does the electrodes have a double layer of iridium? Compared to standard copper spark plugs, the iridium firing pin and iridium electrode inlay provide 4 times higher performance and have longer life spans
- With the new OE Fine Wire design, up to 24% less voltage is required to ignite
- Welding continuously 360 degrees offers increased durability to enhance the life of products
- In addition to providing greater range of heat, copper cores provide greater resistance to preignition and fouling
- There is no need to adjust the gap or apply anti-seize to the pre-gapped and nickel plated threads so installation can be done quickly and easily
- The ground electrode on a spark plug with a tapered ground electrode allows for a better ignition throughout the spark plug’s lifespan.

NGK IX Iridium Spark Plug 4469
There are many reasons why NGK Iridium IX spark plugs are part of the performance enthusiast’s attention to detail. This spark plug is made of pure iridium, which is extremely ignitible, offers superior throttle response, and is superior antifouling as well.
- An innovative ground electrode design that has a taper-cut shape that allows for more flame expansion area
- In today high-performance engines, iridium alloys are ideally suited for their high melting points, providing maximum power and efficiency
- With the central electrode made of fine Iridium wire, you can be confident that the spark will be consistent and durable
- It has superior corrosion resistance and antiseizing properties since it consists of trivalent metals.
Denso Iridium TT Spark Plug 4702
The durability of an OE style plug combined with the power and torque of a high performance plug.
- In the case of DENSO’s 360 degree laser welding process, the iridium center electrode ensures an exceptional bonding quality as well as structural strength.
- Ground electrode with needle tip, 0.77 mm in diameter, promotes higher spark energy and less heat quenching
- Iridium electrodes with a diameter of 0.4 mm provide the smallest diameter of any electrode in the world while still being the most effective
- The patented DENSO iridium-rhodium alloy formula has the highest concentration of iridium compared to competitors, making it more durable and long-lasting.
- As part of DENSO’s 360 degree laser welding process, the center electrode is made of iridium, which ensures exceptional bonding quality and structural strength both in the welding process and in the end product.
- Inductive ground electrode with a needle tip, 0.77 mm in diameter, which promotes higher spark energy and will lead to a reduced heat quenching time
- Electrodes made of iridium with a diameter of 0.4 mm provide the smallest diameter of any electrode in the world, while still providing a higher current density than any other electrode
- A trademarked DENSO alloy formula is one which contains the highest possible concentration of iridium compared to most of its competitors, making it more durable and long-lasting.
Bosch Double Platinum Spark Plug 8105
The Bosch Double Platinum Spark Plugs are designed to provide both performance and long life, so they are the best spark plugs for many OE applications. A platinum firing pin is used by Bosch on the center electrode and a platinum inlay is used on the ground electrode. It has been designed to reduce gap erosion, to increase durability and performance life, while meeting the Original Equipment specifications for double platinum spark plugs.
- In comparison to conventional copper spark plugs, spark plugs with platinum inlay and a plating on the center electrode give them a 3 times longer life span than spark plugs with copper electrodes only
- It is estimated that the fine wire design of OE fire starters requires as little as 24% less voltage to ignite
- Increasing the durability of laser welding by 360 degrees can result in an increase in the life expectancy
- A copper core resists pre-ignition and fouling by providing broader heat range
- There is no need to adjust the gap or apply anti-seize to the pre-gapped and nickel plated threads so installation can be done quickly and easily
