Dinan Iridium Spark Plugs are an excellent upgrade for tuned, and even stock engines, where applicable.* Our spark plugs are made from Iridium - one of the strongest materials available. They last longer than other materials with higher melting points, run cooler, resist preignition, and even require less voltage to produce a strong spark. The iridium electrode with its copper core is harder and stronger than other materials, can dissipate heat more easily, and is better protected from melting, cracking, and other limitations found with standard plugs. Dinan spark plugs are great for high boost, high cylinder pressure, high cylinder temperatures, and high-power situations, and they pair nicely with a set of Dinan ignition coils, where applicable. However, they are not only for tuned and higher output vehicles that may benefit from a plug cooler than the factory heat range – they also are applicable to select non-tuned / stock vehicles as well!* *N54 & N55 COMPATIBILITY: Dinan plugs are numerous steps colder than stock on both the N54 (3 steps colder) and N55 (2 steps colder) and are suggested for tuned, high boost and/or upgraded turbo applications only. They are *NOT* suggested for non-tuned stock vehicles for these speciific applications. If installed on a stock N54/N55 vehicle the plug will not reach its self cleaning temperature and be unable to burn off the combustion deposits leading to fouling, misfires, and a shorter lifespan of the plug.

CTS Turbo is proud to release the S63TU/N63TU 4.4L intake which is a complete replacement for the OEM system. The design intent was to create the largest, highest flowing intake on the market. Features a massive 6' velocity stack air filter and a 3' aluminum intake pipe that connects perfectly to the turbo inlet. An extra turbo heatshield is included in order to keep air intake temperatures as low as possible. Without any extra tuning, peak power gains range from 12 to 20HP (fuel and elevation dependent). All of the components included in the CTS air intake system work flawlessly together to provide increased horsepower and torque throughout the entire power band and an aggressive race-inspired sound. Features: Massive velocity stack reusable air filter 3' smooth air intake pipe Black powder coat for OEM look Great sound and power increase Affordable price without sacrificing quality
