Although the reliability of the Audi A4 can only be compared to its exquisite beauty, it is not uncommon for proud A4 owners to notice that all of a sudden their near-perfect vehicle started to consume more fuel, and its acceleration got slow. These problems are often caused by faulty spark plugs that either do not fire at all or produce sparks that are too weak to ignite the full volume of the mixture of fuel and air. Fortunately, spark plugs are easy to replace: it won’t take you a lot of time and effort to do it on your own.
When deciding on a spark plug to buy, bear in mind that plugs with electrode tips made of copper are usually cheaper, but have limited longevity and average reliability. Plugs that feature such metals as nickel, palladium and platinum are normally more expensive, but offer longer lifetimes and generate stronger sparks. The gap between the electrodes is extremely important for the performance of your vehicle: the wider the gap, the stronger the sparks produced by the plug. In our store, you will find a wide variety of Audi A4 spark plugs that were manufactured by renowned aftermarket companies : there is not a thing that we haven’t taken the utmost care of.
