Bosch Ignition Coil Review
A healthy spark is all you need in order to run your engine, but sometimes, your ignition circuits become problematic and fail to deliver this spark that causes your car to jerk to life. When your car stalls and misfires frequently, you have to replace your ignition coil. This is the part that constitutes your ignition’s primary circuit, which helps build up magnetic fields that charge up the spark plugs. Over time, due to poor engine maintenance and other factors, the windings of the ignition coil will tire and ground, causing the component to be incapable of producing the necessary amount of magnetic field. Replacement of the component must be done to regain the brisk starting of the engine. Bosch is one brand that you can find out there, but before buying its product, let us first put it to the test.
- Sold individually
- Original equipment replacement
- New component
- With boot
- Direct ignition coil
We tested this component on a Volvo V70 and a Porsche 911, and here is what we have to say:
- The component looked good overall. There were no cracks and the terminals were clean and of equal size.
- We checked the resistance of the coil’s primary and secondary resistance using an ohmmeter. We got an average of 0.8 ohm for the primary and around 10,500 for the secondary. We also checked the voltage and got a good reading. The coils produced resistance and voltage that fell under the safe range.
- We drove the V70 and the 911 on the highway for thirty minutes to see if there would be any difference in engine behavior. We could say that the two vehicles ran better because we were able to save more gas. The engine did not misfire, especially when halting at stoplights.
- The six-year-old V70 was having episodes of stalling and starting problems prior to the installation of the new ignition coil. But when the V70 was running with the new coils on, the ignition responded briskly and the engine did not stall when about to park.
- This is one of the cheaper kinds in the market.
- It could have helped if installation instructions came with the product. It was somewhat confusing how to connect the wires of the ignition coil to the correct terminals on the distributor.
Generally, Bosch ignition coils receive acceptable reviews online. These coils have a modern design that makes them more durable. Based from our experiment, the coils have correct specifications and yield a healthy resistance and voltage. Just make sure to buy the one that matches your car’s make, model, and year in order to avoid fitting and performance hassles.
