A Guide to Aftermarket Spark Plugs for the 2001-2010 Volvo S60
Keep your S60’s 5-cylinder engine running strong by choosing the right spark plugs.
- Stick with OEM-equivalent brands like Bosch, NGK, or Denso for the best results in your S60.
- Always verify the correct part number and spark plug gap for your specific engine (non-turbo vs. turbo).
- Do not use anti-seize on modern plugs with plated threads; it can lead to over-torquing.
- Replacing spark plugs is a simple DIY job that can be done in under an hour with basic tools.
Symptoms of Failing Spark Plugs
When your S60's spark plugs start to wear out, your car will give you several warning signs. Ignoring them can lead to worse fuel economy and potential engine damage over time. Look out for these common symptoms:
- Rough Idling: The engine may shake or vibrate when the car is stopped.
- Engine Misfires: You might feel a hesitation or stumble from the engine, especially under acceleration. This happens when a plug fails to ignite the fuel mixture correctly.
- Check Engine Light: A misfire will often trigger the check engine light. Common codes include P0300 (random misfire) or P0301-P0305 (for specific cylinders).
- Poor Acceleration: The car may feel sluggish or less responsive than usual.
- Reduced Fuel Economy: When fuel isn't burned efficiently, your gas mileage will suffer.
- Difficulty Starting: Severely worn plugs can make it hard to start the engine.
Choosing the Right Aftermarket Spark Plugs
When shopping for new spark plugs, you don't have to buy them from a Volvo dealer to get good quality. Many aftermarket brands are the original equipment (OE) manufacturers, meaning they made the part for Volvo in the first place. For the 2001-2010 S60, sticking with these trusted brands is your best bet.
OEM vs. Aftermarket Quality
"Genuine Volvo" spark plugs are typically made by Bosch or NGK. You can often buy the exact same plug from the original manufacturer for less money than the Volvo-branded box. Brands like Bosch, NGK, and Denso are highly recommended by S60 owners and mechanics for their reliability and performance. While budget brands like Autolite or Champion are available, most owners prefer to stick with the proven European or Japanese OEM-equivalent brands for these engines.
Brand Tiers for Your Volvo S60
- Tier 1 (OEM-Equivalent): Bosch, NGK, Denso. These brands are widely considered the best choice. They are often the original part manufacturer and offer excellent performance and longevity. Many come pre-gapped for your vehicle.
- Tier 2 (Quality Aftermarket): Beck Arnley. This brand often sources parts from OEM suppliers, so you may find a Bosch or NGK plug in their box.
- Tier 3 (Standard/Performance): Champion, Autolite, MSD. While functional, these are not the typical go-to brands for Volvo owners. MSD is a performance-focused brand that is likely unnecessary for a stock S60.
Check Your Engine Type!
The 2001-2010 S60 came with different engines (non-turbo, 2.4T, 2.5T, T5). Turbocharged models, in particular, are sensitive to spark plug type and gap. Always verify the correct part number for your specific engine before purchasing. 🎬 See this DIY procedure for replacing your S60's plugs and coils. Using the wrong plug can cause performance issues.

Frequently Asked Questions
How often should I replace my S60's spark plugs?
The recommended replacement interval can vary. For conventional plugs, it's often every 30,000 to 40,000 miles. For longer-life platinum or iridium plugs, it can be 60,000 miles or more. It's best to check your owner's manual, but replacing them every 50,000-60,000 miles is a good practice to maintain performance.
Do I need to check the gap on new spark plugs?
Yes, it's always a good idea. While many iridium and platinum plugs come pre-gapped, they can be dropped during shipping, which can change the gap. For most S60 turbo models, the recommended gap is around 0.028 inches (0.7mm). Always verify the correct specification for your engine.
Should I use anti-seize on the spark plug threads?
Most modern spark plug manufacturers, like NGK and Bosch, advise against it. Their plugs have a special trivalent plating that acts as an anti-seize and prevents corrosion. Using anti-seize can cause you to over-torque the plugs, which can damage the threads in the engine's cylinder head.
What's the difference between copper, platinum, and iridium plugs?
The main difference is the material of the center electrode, which affects performance and lifespan. Copper plugs are the most basic and have the shortest life. Platinum and Iridium are harder metals that last much longer and provide a more consistent spark over their lifespan. Most modern cars, including the S60, perform best with the recommended platinum or iridium plugs.
