Maintaining your Lexus RX 350 involves several key service tasks, and one important aspect is the scheduled replacement of spark plugs. Proper spark plug maintenance ensures optimal engine performance, fuel efficiency, and longevity.

When to Replace Spark Plugs on a Lexus RX 350

Lexus typically recommends replacing spark plugs every 60,000 to 100,000 miles for the RX 350, depending on the model year and driving conditions. Checking your owner’s manual will give you the exact interval, but keeping up with this maintenance helps avoid engine misfires and poor fuel economy.

Cost Breakdown for Spark Plug Replacement

  • Parts: Genuine Lexus spark plugs usually cost between $15 and $30 each. The RX 350 uses six spark plugs, so parts can total $90 to $180.
  • Labor: Labor costs vary depending on the service center but typically range from $100 to $200 due to the time needed to access the spark plugs.
  • Total Estimated Cost: Expect to pay between $190 and $380 for a complete spark plug replacement at a dealership or reputable shop.

Tips to Save on Spark Plug Maintenance

  • Consider having the service performed during a routine maintenance check to save on labor costs.
