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 output vehicles that benefit from a plug cooler than the factory heat range. They are great for high boost, high cylinder pressure, high cylinder temperatures, and high power situations, and they pair nicely with a set of APR ignition coils, where applicable.
My tuned 17' R has had RS7 plugs and APR coils for awhile without issue, but I'm ready for a new set.
Got the APR 6-pots in the front, and now fabin' bits to sort out the APR 4-pots in the rear.
I have 75K on my CC Sport with APR Stage1+ Tune. I recently changed my plugs and put APR coils in not sure if got any real power but the car feels so much better. At $27 a coil why not use APR?
Our pads are what I would call an Advanced street pad. It's suitable for daily driving from dead cold with no warm up to 630 C (1166F). The pads will remain fade-free up to maximum operating temperature.
They pair perfectly with the APR Direct Replacement Advanced Street Pads, and provide a no-compromise solution for spirited daily driving.
APR Direct Replacement Brake Discs are a plug-and-play upgrade for your factory brakes. They provide reduced brake fade, improved brake consistency, and excellent modulation, especially during repeated consecutive braking applications or spirited driving. The rotors have improved resistance to distortion, warping, and cracking at high temperatures. They pair perfectly with the APR Direct Replacement Advanced Street Pads, and provide a no-compromise solution for spirited daily driving.
Please get rid of those APR Ignition Coils and RS7 Spark Plugs. You are most likely encountering the misfiring from those alone.
I'd recommend getting rid of those APR coils before tuning, they cause so many headaches
