In the world of automotive maintenance, the term "tune-up" harkens back to a bygone era when vehicles relied on distributors, spark plug wires, and points-style ignition systems. These outdated systems have given way to modern coil-on-plug style ignition systems, featuring zero moving parts and extended service intervals. Today, we delve into the world of BMW spark plugs, exploring the pivotal role they play in optimizing your vehicle's performance.
The Evolution of Spark Plugs
Starting with the 1999 year model, BMW introduced platinum-tipped spark plugs into their factory settings, later transitioning to iridium-tipped spark plugs in 2006. These advanced spark plugs have a remarkable longevity, requiring replacement only after 100,000 miles of service. It's a testament to BMW's commitment to engineering excellence.
(Note: This service interval applies to most BMWs produced between 1999 and March 2009, excluding M and turbocharged models.)
High-Performance Models and Their Spark Plug Needs
If you're the proud owner of a BMW Motorsport model, such as the E36/7 and E85 M Roaster/Coupe, or the E36 and E46 M3, your vehicle comes equipped with two ground strap spark plugs. These high-performance engines, built for exhilarating drives, tend to wear out their spark plugs more quickly, necessitating a replacement at 60,000 miles. Typically, this falls in line with the Inspection Two Services.
Shorter Intervals for Motorsport Marvels
Newer BMW Motorsport models, like the E60 M5, E63/64 M6, and E90/92 M3, maintain a shorter spark plug service interval. To keep these V10 and V8 powerhouses performing at their best, spark plug replacement is recommended every 37,000 miles.
Turbocharged Models and Their Needs
If your BMW boasts a turbocharged engine like the N54 or N63, found in models such as the 135i, 335i, 535i, X5, X6, 2009 and newer 750i, or the 2010 and newer 550i, you'll be working with copper-tipped spark plugs. These require more frequent attention, with a replacement needed every 37,000 miles, often coinciding with the third oil service or vehicle check service.
Keeping the Newest Models in Peak Condition
The latest BMW models, equipped with the new N20 or N55 turbocharged engines or the N52TU engine (found in models like the 2010 and newer 535i, 535i GT, 128i, 328i, X3, X5, etc.), maintain a spark plug replacement schedule of every fourth engine oil service or 60,000 miles.
Replacing your BMW's spark plugs is crucial for maintaining optimal ignition and overall vehicle performance.
