HQPASFY Ignition Coil & Spark Plug Set (x6) — BMW 3.0L N52/N54

The ignition coils are application-specific, built to match the electrical characteristics and physical fitment of the original BMW units. They slot in as direct replacements for OEM part numbers including UF592, C1638, 0221504470, 12137594937, and 12137562744, among others — no splicing, adapters, or bracket modifications required. The spark plugs pair aluminum and porcelain construction to resist the heat cycles and corrosion that wear down conventional plugs over time, helping maintain a strong, consistent spark across all six cylinders.

Running a matched coil-and-plug set matters more than most owners realize. Mismatched components can lead to uneven combustion, reduced fuel economy, and elevated emissions even after a partial repair. By replacing all six coils and plugs simultaneously, you eliminate the guesswork and give the engine a clean baseline — restoring the crisp throttle response and smooth idle these motors are known for when properly maintained.

Installation is straightforward enough for a confident DIYer with basic hand tools, and no dealer-level programming is needed. The entire kit is backed by a 36-month warranty, making it a practical alternative to OEM pricing without sacrificing the fitment accuracy your BMW requires.
