Best Ignition Coil For Mercedes GL450 FAQ
How do I know if my GL450 ignition coil needs replacement?
The most common signs are engine misfires (feeling a shake or stutter), rough idling, poor acceleration, and increased fuel consumption. In severe cases, the Check Engine Light (CEL) will flash or remain solid, often accompanied by diagnostic codes like P0300 through P0308 (misfire codes). If your GL450 is a V8, and one coil fails, it is usually wise to replace the entire set of eight soon after.
Is it necessary to replace all 8 ignition coils at the same time on my V8 GL450?
While you only must replace the failed coil, it is strongly recommended to replace the entire set, especially on V8 engines like the GL450. Coils age similarly, and when one fails, the others typically aren’t far behind. Replacing the full set ensures consistent performance across all cylinders and avoids repeated labor costs.
What is the difference between the UF-535 and UF-741 reference numbers for the Mercedes GL450?
The GL450 uses different coil types depending on the engine generation. The UF-535 coils are generally associated with the earlier M273 4.6L V8 engines (found in models around 2007-2012). The UF-741 (or similar UF-733/UF-748) coils are typically used for the newer M278 4.7L Biturbo V8 engines (found in models starting around 2013). Always check your vehicle’s engine code or existing coil part number to ensure compatibility.
Can a bad ignition coil damage other parts of my Mercedes GL450 engine?
Yes. A continuously misfiring cylinder allows unburnt fuel to enter the exhaust system. This can rapidly damage expensive components like the catalytic converters and oxygen sensors due to excessive heat. Addressing a coil failure quickly is crucial for protecting these components and ensuring proper emissions control.
How long does an ignition coil typically last on a Mercedes-Benz GL450?
Ignition coil life varies based on driving habits and environment, but on the GL450, they typically last between 75,000 and 100,000 miles. Extreme heat, constant stop-and-go driving, and infrequent spark plug replacements can shorten their lifespan considerably.
Should I replace my spark plugs when replacing the best ignition coil for mercedes gl450?
Absolutely. Spark plugs and ignition coils work together, and old, worn-out spark plugs require the coils to output significantly higher voltage to bridge the spark gap. This extra stress shortens the life of even the best ignition coil for mercedes gl450. Replacing the spark plugs alongside the coils ensures maximum efficiency and longevity for the entire ignition system.
