BMW X4 Spark Plugs

Autolite has over 100 years of engineering experience and has sold over 11 billion plugs. Designed and engineered in the USA, the Autolite Iridium XP spark plugs feature an iridium-enhanced 0.6mm finewire design and patented platinum sidewire technology to provide better overall durability and a more focused ignition for enhanced ignitability and performance. Features double Iridium-enhanced alloy technology center electrode for improved durability and wear resistance.

Increased performance with World’s smallest Iridium Center Eletrode (0.4mm).

BOSCH Double Platinum Spark Plugs are engineered to deliver both performance and long life, representing the best of OE spark plug technology. BOSCH utilizes a platinum firing pin on the center electrode and platinum inlay in the ground electrode. This design reduces gap erosion, increases durability and performance life while meeting Original Equipment specifications for double platinum spark plugs.

Champion Double Platinum Power spark plugs combine a platinum fine-wire center electrode with platinum center and ground electrodes and exclusive Heat-Active alloy, ensuring powerful performance, longer service life and precise spark focus for optimal combustion. Champion your engine with spark plugs engineered to improve efficiency and keep your vehicle running at its best.

NGK Laser Iridium High Ignitability spark plugs offer the best combination of performance and longevity. Engineered specifically for OE applications, Laser Iridium High Ignitability spark plugs are tested to the highest standards to ensure quality and durability. Iridium tipped center electrode provides durability six times harder than platinum. NGKs high grade pure alumina ceramic and 98 percent pure copper core prevents the spark plug from overheating while providing reliable starts. Laser Iridium High Ignitability spark plugs feature raised platinum pad or platinum fine wire tip on the ground electrode for even wear in distributorless ignition systems and improved spark performance.

Manufactured to the strictest OE performance, durability and emissions standards.

Durability of an OE style plug combined with Power & Torque of high performance.

The Autolite Double Platinum spark plugs are engineered for exceptional performance and longevity, making them a top choice for distributor-less ignition system (DIS) engines. Featuring a platinum-to-platinum design, these spark plugs effectively prevent gap erosion, reduce misfires, and ensure a longer service life compared to traditional copper or single-platinum plugs. The yttrium-enhanced ground electrode provides superior heat transfer, allowing the spark plug to withstand high temperatures and pressure for enhanced durability. Its high alumina ceramic insulator ensures optimal thermal conductivity and dielectric strength, while the multi-rib insulator design prevents flash-over for reliable performance. With a long projection center electrode and flat seat type, these spark plugs are built for precision and efficiency. Both the center and ground electrode tips are crafted from platinum, ensuring consistent performance and reliability. Designed for performance-grade applications, these spark plugs deliver unmatched value and come with a limited warranty for added peace of mind.
