2004 Mitsubishi Lancer Ignition Coil Packs

 

The 2004 Mitsubishi Lancer ignition coil design was updated and improved for the 2.4L 2004 model year with 4 individual ignition coils as opposed to two ignition coils for the 2.0L models. This new design came with advantages which allowed the ECU to have more control over the ignition timing, increasing fuel economy, emissions and power slightly. The only drawback is the cost to replace. Instead of two ignition coils, you now have 4 that can fail over time. The good news is that this repair doesn't have to be as expensive as you'd think it would be. We have the entire set of 4 ignition coils for your ' 04 Lancer for prices that beat any local store. Plus the quality is the same or better. We do this by purchasing from the same exact manufacturers that the big brands purchase from, but instead of selling through the distribution channel, we offer them directly to you through our website. This allows us to pass on the savings to our customers. A few things that can cause these ignition coils to fail are improperly washing the engine bay, old spark plugs and cracks from old age. As your spark plugs wear, the gap increases. This will causes the resistance to rise, and force the ignition coil on plugs to work harder. Using the wrong spark plugs with a gap too large can also cause this issue. Another way that these can be damaged (common) is by unbolting the ignition coil and lifting it up and off of the spark plug while the engine is running. Lancer owners do this while trying to diagnose a misfire, but the problem with lifting the coil up and off of the spark plugs removes the ground. The surge of high voltage has nowhere to go, and may go back into the coil, blowing out the primary low voltage windings. The worst case scenario is the ECU taking damage from the high voltage, so we recommend to not do this. The easiest way is by using an OBDII scanner. These devices cost under $20 at many online retailers, and will save you so much money and time. The last reason these coil packs can fail is from humidity. If you live in a humid region, there is not much you can do about this.
