Subaru WRX Ignition Parts

The ignition system of a vehicle plays a critically important role for proper operation of its engine. Once a proper fuel-air mixture enters the cylinders it should be ignited to allow the engine to convert kinetic energy into mechanic one. This is when the ignition system enters the scene. Its purpose is to ignite the fuel-air mixture at the right time, so the expanding gases can do the maximum amount of work. If any ignition part is worn or damaged, the system will provide a spark at the wrong time resulting in reduced power and increased gas consumption and emissions.

If your Subaru WRX is hard to start or misses under load and idle rough, your ignition system should be checked for worn or damaged parts. Once you have found the faulty component don''t wait too long to replace it before you get stuck in the middle of nowhere. With our wide catalog of Subaru WRX ignition parts, you don't have to waste your time running out to the auto parts chain store and standing in lines. You'll spend a minute or so to find the product you need to restore your vehicle to excellent performance at the most attractive price available on the market.

    Since their inception at the start of the 20th century, motor vehicles with gasoline burning engines have needed a precise way to deliver an electrical spark to each of the engine's cylinders. (Note that diesel engines do not rely on an electrical spark to ignite the fuel-air mixture.) For much of the past 100 years, the spark has been delivered by the ignition...
    The question of whether to buy parts from an automotive dealer vs. ones from aftermarket manufacturers is as age-old as the automobile itself. Below, we'll take a look at things worth considering to help you make a better choice if you're facing that same question. Automobile manufacturers and dealerships always advertise the fact that their parts are "genuine"...
