APR Iridium Pro Spark Plugs are the excellent upgrade for tuned engines. Our spark plugs are made from Iridium, which is one of the strongest materials you can use in this type of application.
They run cooler, resist preignition, last longer than other materials with higher melting points, and even require less voltage to produce a strong spark. The electrode is harder and stronger than other materials, can dissipate heat more easily, is better protected from melting, cracking, and other limitations found with standard plugs.
These plugs were designed for use on tuned and higher …

APR Ignition Coils are designed to be a direct plug-and-play upgrade to factory coils, and provide greater energy output, ensuring a stronger and more consistent spark. The commonplace replacement of factory ignition coils with those taken from the higher output Audi R8 is popularly believed to provide greater energy output. However, testing proves that they are no more powerful than the factory coils that are found on other engines. APR Ignition Coils increase energy output by up to 6% over stock. They are a direct upgrade or replacement, and come with a unique red …

The APR High Pressure Fuel Pump (HPFP) increases maximum volume of fuel the HPFP can deliver by 37% over stock! In doing so, the direct injection fueling system is capable of satisfying fueling requirements set forth by high horsepower setups. This is accomplished by increasing the displacement of the pump using high quality components to exacting tolerances. On the B9 2.9T we achieved an additional 37 AWHP and 50 AWFTLBS over our Stage 1 (E85) ECU Upgrade by adding the pump and running our Stage 1+ (E85) ECU Upgrade!
