Dinan N20/N54/N55/S55/S63 Iridium Spark Plug - Heat Range 9 - 12mm Thread - EU Made

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. N20/N54/N55/S55/N63/N63TU/S63/S63TU Always check sizes, gap, and heat range specs before installing. Installation of the wrong length plug can cause damage to the engine. You must verify this before installing the plug.

Upgrade your BMW with the Dinan N20/N54/N55/S55/S63 Iridium Spark Plug, designed for optimal performance and longevity. Crafted from durable iridium, this spark plug features a copper core with a hardened iridium electrode, providing a higher melting point and superior heat dissipation compared to standard plugs. This results in cooler operation, increased resistance to pre-ignition, and a longer service life, making it an excellent choice for both high-performance tuned engines and stock vehicles. The design is optimized for hard-to-ignite fuels like ethanol, ensuring reliable spark delivery across various fuel types. Its heat range 9 classification makes it compatible with a wide range of BMW models, including 2010 135i, 335i, 750i, X5, and more, offering a seamless upgrade for enthusiasts and professionals alike. The spark plug features a 12mm thread diameter, 26.5mm reach, and a 14mm bi-hex nut, facilitating straightforward installation with a torque of 17 Nm. This product is made in the EU and is engineered to fit specific BMW engines, with verified dimensions and gap settings to ensure proper installation and optimal engine performance. Notably, the plug’s ceramic insulator and projected insulator design enhance durability and heat management, promoting consistent engine operation. The spark plug's lower voltage requirement also contributes to more efficient ignition, helping to reduce electrical stress on your vehicle’s ignition system. Ideal for use with Dinan ignition coils, this single spark plug is a reliable upgrade that enhances your vehicle's efficiency, power output, and fuel economy, making it a valuable addition to your BMW maintenance routine.
