A Guide to Replacing Spark Plugs on Your 2011-2017 Volvo S60
Keep your Volvo's engine running smoothly by understanding when and how to replace your spark plugs.
- Confirm your S60's engine (4-cyl, 5-cyl, or 6-cyl) before buying, as spark plugs are not interchangeable.
- Using Genuine Volvo plugs or high-quality Iridium plugs from Bosch, NGK, or Denso is strongly recommended for best performance.
- Symptoms like rough idle, poor acceleration, and a drop in MPG are strong indicators that your spark plugs need inspection.
- Replacement is a manageable DIY task, but using a torque wrench for proper installation is critical to prevent engine damage.
Signs of Failing Spark Plugs in Your S60
When your spark plugs are wearing out, your Volvo will give you several warning signs. You might feel the engine shake or vibrate when you're stopped at a light, which is known as a rough idle. Another common symptom is an engine misfire, where the car may hesitate, jerk, or lose power when you accelerate. Other signs include difficulty starting the engine, especially in the cold, and a noticeable decrease in your gas mileage. If the problem is bad enough, the 'Check Engine' light will turn on.

Aftermarket Brand Quality Tiers
| Tier | Brands | Assessment |
|---|---|---|
| OEM & Premium Aftermarket | Genuine Volvo, Bosch, NGK, Denso | Genuine Volvo plugs are often made by Bosch, NGK, or Denso to Volvo's exact standards and are highly recommended by specialists for guaranteed compatibility. Bosch, NGK, and Denso are top-tier aftermarket brands offering Iridium and Platinum plugs that provide excellent performance and long life, often meeting or exceeding original quality. |
| Standard Aftermarket | Autolite, Champion | These brands offer a reliable and budget-friendly option for replacement. While they perform the job, they may not have the same longevity or performance characteristics as the premium Iridium plugs, especially in Volvo's turbocharged engines. |

Frequently Asked Questions
How often should I replace the spark plugs on my Volvo S60?
The recommended replacement interval can vary. Volvo's official schedule may suggest around 60,000 miles. However, many mechanics and enthusiasts, especially for turbocharged models, recommend a shorter interval of 50,000 miles to maintain peak performance. High-quality Iridium plugs can last longer, but it's best to check your owner's manual and inspect them for wear.
What is a 'spark plug gap' and do I need to set it?
The spark plug gap is the small space between the center and ground electrodes. The spark must jump this gap to ignite the fuel. Most modern spark plugs from brands like Bosch and NGK come 'pre-gapped' for your engine. However, it's a professional tip to always double-check the gap with a feeler gauge before installation to ensure it matches your engine's specifications.
Is it okay to use aftermarket spark plugs instead of Genuine Volvo?
Yes, but it's important to choose a high-quality brand. Many Volvo specialists prefer using Genuine Volvo plugs because they are guaranteed to work perfectly. However, premium aftermarket brands like Bosch, NGK, and Denso are often the original manufacturers for Volvo and offer excellent Iridium or Platinum options that are a reliable alternative. Avoid the cheapest options, as they may not perform well in Volvo's turbocharged engines.
Can I replace the spark plugs myself?
Yes, for many owners, this is a very feasible DIY job that can be done with basic tools. The process involves removing the plastic engine cover, unplugging and removing the ignition coils that sit on top of the plugs, and then using a special spark plug socket to remove and replace the plugs. It is critical to use a torque wrench to tighten the new plugs to the correct specification to avoid damaging the engine.
