You might also experience hesitation when you accelerate, a general loss of power, or a noticeable drop in fuel economy. 🎬 Watch: 5 alarming signs of bad spark plugs In some cases, a loose or failing plug can overheat and cause damage to the electrode, leading to a more severe misfire.
Choosing the Right Aftermarket Spark Plug
For a classic car like the 1976-1982 Volvo 264, original equipment (OEM) quality is often achievable with aftermarket brands, as many of them were the original suppliers. The V6 engine in your 264 was designed in an era of simpler, standard copper spark plugs. While modern platinum and iridium plugs are available, many Volvo enthusiasts report the best performance by sticking with high-quality copper plugs, which these older ignition systems were designed for. Using expensive precious-metal plugs may not provide any benefit and could potentially cause minor running issues.
Brand Tiers for Your Volvo 264
- Top Tier (Recommended): Brands like NGK and Bosch are frequently recommended for classic Volvos. NGK is often praised for its reliability and consistent performance. Bosch is a common OEM supplier for European cars, though some users have mixed opinions.
- Quality Alternatives: Denso, Champion, and Autolite are all reputable brands that produce reliable spark plugs suitable for your 264. They offer a good balance of quality and value.
- Budget-Friendly: Brands like Skyward fall into the budget category. While functional, they may not offer the same longevity or quality control as the more established brands.
Check the Gap!
No matter which brand you choose, always check the spark plug gap before installation. The recommended gap for the Volvo 264's V6 engine is between 0.028 and 0.032 inches (0.7mm - 0.8mm). Most plugs are not pre-gapped specifically for your car and will need adjustment with a simple gapping tool.

Frequently Asked Questions (FAQ)
How often should I replace the spark plugs on my Volvo 264?
For standard copper spark plugs, a good rule of thumb is to replace them every 15,000 to 30,000 miles, or as part of a regular tune-up. This ensures your engine maintains optimal performance and fuel efficiency.
Are more expensive iridium or platinum plugs worth it for my car?
For the 1976-1982 Volvo 264, expensive precious-metal plugs are generally not necessary. The original ignition system is designed for standard copper plugs, and many owners find they perform best with them. Sticking with a quality copper plug from a brand like NGK or Bosch is a reliable and cost-effective choice.
What tools do I need to change the spark plugs?
The job is straightforward and requires basic tools. You will need a ratchet, a few extensions, and a spark plug socket (confirm if you need a 5/8" or 13/16" socket for your chosen plugs). A spark plug gapping tool is also essential to set the gap correctly.
Do I need to use anti-seize or dielectric grease?
It is common practice to apply a very small amount of anti-seize compound to the plug threads to prevent them from getting stuck in the cylinder head. However, be careful not to get any on the electrode. Dielectric grease should be applied to the inside of the spark plug wire boot to protect against moisture and ensure a good connection.
