NGK Laser Iridium Spark Plug Box of 4 (SIZKBR8A8HS)

NGK is well-known for making reliable ignition components, and their Laser Iridium spark plugs are a prime example of that. If you're working on your 2011 or 2012 BMW Alpina B7, these are the exact type of plugs you'll want to install to keep that engine running smoothly. They're designed to be a direct OE replacement, meaning they're built to the same high standards as the original parts your car came with.

What makes these plugs stand out is the iridium center electrode, which is significantly harder and more durable than platinum. This means a more consistent spark and a longer lifespan for the plug. You'll also find a platinum fine wire tip on the ground electrode, which helps ensure even wear, especially in modern distributorless ignition systems. The pure alumina ceramic insulator helps manage heat effectively, and the copper core further aids in removing excess heat from the plug tip, preventing overheating and ensuring reliable starts.

These plugs also feature trivalent metal plating, which gives them excellent resistance to corrosion and makes them easier to remove down the road. They come with triple seals to prevent any leaks. If your Alpina B7 originally came with iridium spark plugs, these NGK Laser Iridiums are the perfect choice for a replacement.
