  • Ignition Coils & Platinum Spark Plugs for 4.7L 2001-2009 Toyota Tundra Sequoia

    Types of Ignition Coils:

     

    • Conventional Ignition Coils: Conventional ignition coils, also known as canister-style coils, have been widely used in older vehicles. They are typically mounted outside the engine and consist of a metal canister housing the primary and secondary windings. These coils are connected to the distributor, which distributes the high voltage to the spark plugs. Conventional ignition coils are relatively simple in design and are known for their durability and reliability.
    • Distributorless Ignition System (DIS) Coils: With the advancement in ignition technology, distributorless ignition systems (DIS) have become more prevalent. DIS coils are typically mounted directly on the spark plugs or close to the spark plugs, eliminating the need for a distributor. Each coil is responsible for supplying high voltage to a specific spark plug. The DIS system uses sensors to determine the precise timing of spark production for each cylinder. DIS coils offer improved ignition performance and efficiency compared to conventional coils.
    • Coil-on-Plug (COP) Ignition Coils: Coil-on-plug (COP) ignition coils take the concept of DIS coils a step further. In COP systems, each cylinder has its own ignition coil mounted directly on the spark plug. This configuration eliminates the need for spark plug wires and provides even more precise and efficient ignition. COP ignition coils offer enhanced spark energy and better combustion control, resulting in improved engine performance and reduced emissions.

     

    Ignition coil problems:

    You will be glad to know that ignition coil failures are common. Symptoms of a failing ignition coil include:

    • Engine shaking
    • Lack of power
    • Spluttering
    • Check Engine Light on the dashboard.

     

    What you need replacement:

    • New ignition coils
    • Dielectric grease
    • Gloves
    • Repair manual
    • Ratchet and socket set
    • New spark plugs (if necessary)

     

    STEP 1:

    Firstly, you need to remove the negative battery cable

    STEP 2:

    Now you need to locate the coil packs or your ignition coil in your car’s engine bay. Cars with coil packs will generally have them mounted near a valve cover. Coil on plug ignition coils can be found near or directly over each spark plug. Be sure to remove any plastic engine covers to gain access to the coils.

    STEP 3:

    Then, unplug the wiring harness. Do this by pushing the tab and pulling off the electrical connector.

    STEP 4:

    Remove retaining bolts by holding your car’s coil in one place. Once this is unbolted, your coil pack can be removed. Some models may have locking tabs that need to be opened.

    STEP 5:

    If it’s time to change the spark plugs, this is your chance to do so. If you have an older model of car we recommended replacing ignition coil and spark plugs at the same time.

    STEP 6:

    Using the dielectric grease, apply to the end of the coil-on-plug style. Doing this prevents the boot from sticking to the spark plug and keeps water out.

    STEP 7:

    You can now slide the new coil into place, pressing firmly to hear a click. Reattach the electrical connection and the coil pack retaining bolt.

    STEP 8:

    If necessary, repeat this process until all units have been replaced. Then, reconnect the negative battery cable.
