Signs of Failing Spark Plugs
When spark plugs wear out, they can't create a strong enough spark at the right time. This can cause a range of problems. You might notice your engine idling roughly or shaking when you're stopped. Other common signs include difficulty starting the engine, a noticeable drop in fuel economy, and sluggish or slow acceleration. If the problem is bad enough, it will cause an engine misfire, which can trigger the 'Check Engine' light 🎬 Watch: 7 common symptoms of bad spark plugs and repair costs on your dashboard.
Choosing the Right Aftermarket Spark Plug
Your Volvo XC60's modern engine requires high-quality iridium spark plugs for long life and performance. When shopping for aftermarket parts, it's important to know that not all brands are created equal. Here’s a simple breakdown:
- Tier 1 (OEM-Equivalent): Brands like NGK and Bosch are often the original equipment manufacturers for Volvo. This means the NGK or Bosch plug you buy from an auto parts store can be the exact same part as the one sold in a Genuine Volvo box, but at a lower price. For your XC60, choosing an iridium plug from one of these brands is a reliable and cost-effective choice.
- Tier 2 (Reputable Aftermarket): Denso is another well-respected Japanese brand that produces high-quality iridium spark plugs that meet or exceed OEM specifications. They are a solid alternative if you're looking for another option besides the OEM suppliers.
Pro Tip
Always verify the part number fits your specific XC60 engine (T5, T6, or T8). The 4-cylinder engines in this generation use the same plug, but it's always best to double-check. Using the wrong type of plug, like a cheaper copper or platinum one, can cause poor performance and engine issues.
Known Issues and Service Bulletins
There are no active recalls for spark plugs on the 2018-2024 Volvo XC60. However, Volvo did issue a Technical Service Bulletin (TSB S29842) for earlier 2015-2016 models with the same engine family, addressing potential spark plug cracking. This led to an improved plug design. The parts available today, like Genuine Volvo part number 32290011, are the result of these improvements, making it important to use the currently specified part for reliability.

Frequently Asked Questions
How often should I replace the spark plugs on my XC60?
For the 2018-2024 XC60 with iridium plugs, the recommended replacement interval is typically every 60,000 miles to maintain peak performance. However, your owner's manual has the most precise recommendation for your vehicle.
Is it hard to replace the spark plugs myself?
For a moderately experienced DIYer, this is a very manageable job. It involves removing the plastic engine cover and the ignition coils that sit on top of each plug. The main special tool you'll need is a 14mm thin-wall magnetic spark plug socket with an extension. The job typically takes about an hour.
🎬 Follow this step-by-step guide for XC60 T5 and T6 enginesWhat happens if I don't replace my spark plugs?
Ignoring worn spark plugs will lead to worsening symptoms like rough running, poor fuel economy, and hard starting. A continuous engine misfire can cause unburned fuel to enter the exhaust system, which can quickly damage the expensive catalytic converter, turning a simple maintenance job into a very costly repair.
Do I need to gap the new spark plugs?
No. The recommended iridium spark plugs from brands like NGK, Bosch, and Genuine Volvo come pre-gapped from the factory. Attempting to gap them can damage the fine iridium tip. You should only verify the gap is correct if you suspect it was damaged in shipping.
