Ignition Coil

We have 2,292 Items for Ignition Coil In-stock.

Your ignition coil functions similarly to a transformer. It operates with a 12-volt source producing output current at the same time that input current is applied. By efficiently building up a magnetic field, it multiplies the voltage of electricity provided by a battery source enabling your engine to achieve quick ignition. Your vehicle may have specific ignition system specifications geared towards optimum engine performance with utmost consideration on fuel economy. Due to prolonged usage, stock ignition coils will eventually need replacement. Get back the efficiency of your ignition system performance by immediately acting on the first sign of coil failure to continually enjoy fuel efficiency and performance gains. As a vital component of your engine ignition system, the reliable service of your ignition coil is emphasized in achieving quick ignition. It serves as an induction coil which multiplies the amount of electricity supplied by your engine battery to start up your engine. As a form of autotransformer with a contact breaker, it supplies the ignition system with high voltage of electricity required by the spark plugs of an internal combustion engine to start engine run with minimal fuel wastage. In modern ignition systems specifications, smaller coils used. One coil for each spark pug or one coil serving two spark plugs is used so a four-cylinder engine car may employ two coils. To ensure quick ignition, investing with premium quality ignition coil is a sure fire solution to excellent ignition system performance. With its heavy duty features and longer life efficiency, it yields miles and miles of reliable service resulting to engine power boost and better fuel mileage. In case your stock ignition coils go bad, prolonging its use compromises fuel efficiency and overall engine performance.

Helpful Tips for Ignition Coil Shopping

Your vehicle won't run without a properly working ignition coil unless it has a diesel engine that depends on compression to ignite the fuel/air mixture or a vintage car that uses a magneto ignition system. You need the ignition coil to convert the battery's low voltage into thousands of volts, which are required to produce an electric spark in the spark plugs to ignite the fuel. Without it, you would have to push your car for it to move.

What is an ignition coil made of?

Early ignition coils were made from varnish and paper that has insulated high-voltage windings. These were put inside a draw-steel can and filled with asphalt or oil to provide insulation and protect it from moisture. Nowadays, the coils in modern vehicles are cast in filled epoxy resins that seep into any voids within the winding.

How to select the right ignition coil for your car

If you are not looking for a component that will enhance your performance, you can get a stock replacement ignition coil to replace an old or busted one. But, there are also coils that are made for specific road use. These are street or strip coils and race only coils. The street coils are normally rated from 35,000 to 55,000 volts. These coils can give a significantly greater performance than stock ignition coils. They provide easier and quicker starting, better throttle response, and improved gas mileage because you are igniting more fuel than before and producing more power through a more complete combustion of the air-fuel mixture.

Another thing that will help you choose the best ignition coil is by knowing what kind of distributor your car has. This will help you minimize your choices for a coil. If you have an HEI type of distributor, then should only buy an ignition coil that can fit within the distributor cap or one that entirely replaces the distributor cap. Externally mounted coils for "points style distributors" are the kind of coils that you can find the most in the market. If your ignition system doesn't have a distributor, you will still need an ignition coil for it to operate.

So, determine the use of your vehicle and what type of distributor you have to be able to choose the right ignition coil for your ride.

How Much Does It Cost?

You should be able to find top-quality ignition coils within a price range of about 20 to over 100 USD, depending on whether you're buying them individually or in packs of 3, 6, 8, or 10.

Installing a New Ignition Coil

Since it is very crucial to have a properly working ignition coil in your vehicle, always be alert about symptoms that indicate if it is about to fail. A well-maintained automobile should perform with constant range of about 1,000 RPMs. If your car's RPMs decrease while it is idle or if the check engine light illuminates or flashes, you may be experiencing a misfire. A misfire is a sign that there is something wrong with the ignition coil or the spark plug. When it is clear that you have a busted ignition coil, get a premium-quality replacement to restore the performance of your vehicle.

Below are the things you will need in installing a new ignition coil and the instructions to do so.

(Note: These are general instructions for all types of vehicles.)

Things Needed:

  • Spark Tester
  • Test Light
  • Safety glasses
  • New Ignition Coil

Optional tools:

  • Phillips screwdriver
  • Flat-head screw driver
  • Combination wrench set

Difficulty Level: Moderate

Safety Reminder: Remember to put on safety glasses when working on your automobile. You can also wear other personal protective equipment (PPE), such as closed toe shoes and latex gloves.

  1. Lift the hood of your car and find the ignition coil. It is usually close to the distributor, if your automobile has one.
  2. Attach the spark tester to the ignition coil output.
  3. Start the engine to see if there will be a spark.
  4. Follow a wiring diagram to figure out if the coil is power or ground side controlled. If it is ground controlled, join the test light clip to the battery's power side and touch the test light to coil's negative side.
  5. Start the engine again and see if the test light bulb will flash.
  6. Have the coil disconnected from the negative battery terminal and electrical connections.
  7. Take out the coil wire from the cap.
  8. Take out the old ignition coil from your automobile and put a new one its place.
  9. Perform the removal procedure in reverse to do the installation.
  10. Start your car and take it on a road test to observe if the ignition coil is working correctly.
