Iridium or platinum spark plugs—which is superior?
The melting point of iridium is 700 degrees greater than that of platinum, and it is reported to be six times tougher and eight times stronger. Spark plugs made of iridium feature incredibly tiny electrodes and good wear characteristics. Iridium spark plugs can live up to 25% longer than comparable platinum spark plugs because of their durability.
Iridium spark plugs include a core electrode made of a thin wire that is intended to carry electricity more effectively and improve firing efficiency.
This valuable metal comes at a cost. Spark plugs made of iridium are often the most expensive, costing between $8 and $15 each.

Should I swap out my BMW’s ignition coils all at once?
Coil packs are dependable and should endure for the entire life of the car. There is no need to replace everyone if one of them behaves badly. However, you should replace them all if one pack begins to malfunction after the odometer has traveled about 75,000 miles.
How frequently should coil packs be changed? They don’t need to be changed until symptoms start to appear. Most of the time, they don’t need servicing until they’ve traveled 120,000 to 150,000 miles.
How durable are BMW coil packs?
Your BMW’s ignition coils’ openings are so near to the engine that with time, heat and vibration might harm the coil housing. The typical lifespan of a BMW ignition coil is around 140,000 kilometers. The lifespan of your coils may drastically reduce if you frequently strain your car’s performance. You should prepare to replace your coils every 20,000–25,000 miles if you’re one of the enthusiasts with modified BMWs who enjoys pushing the limits of your vehicle.
Other factors that contribute to ignition coil failure include faulty spark plugs, oil leaks, and engine water corrosion. It’s possible that a damaged spark plug won’t conduct electricity effectively. Due to the excessive heat produced on the insulator side, this can eventually cause the coil housing to melt. Oil leaks will corrode the spark plug and coil connection, decreasing conductivity and ultimately blocking a spark. Finally, water damage will undoubtedly short the circuit formed by the connection between the ignition coil and the spark plug.
How much does a BMW tune-up cost?
The usual cost of a tune-up for a BMW is between $200 and $400, but if you also require an oil change, the cost may exceed $500. BMW advises having your car tuned up every year or every 10,000 kilometers.
Some of the most well-known luxury and high-performance vehicles are made by BMW. You certainly adore your BMW, but repairs and maintenance may be quite pricey. While tune-ups are an investment, having your BMW tuned up on a regular basis can help stop smaller problems from becoming bigger ones.
When changing spark plugs, should I replace the ignition coils as well?
Hello. Whether or not the vehicle will make that drive truly relies on its general condition. Spark plug replacement is a nice place to start maintenance, but I would absolutely check all the fluids and give the car a thorough checkup. It can be a huge financial mistake to replace the coils while changing the plugs because they only need to be replaced when they break. Consider using YourMechanic to get the car thoroughly inspected before your road trip if you want to have it checked out, as a qualified mechanic may come to your home or workplace.
