Spark Plugs — Price Comparison

Spark Plugs for 2025 Volvo Xc90

Spark plugs on a 2025 Volvo Xc90 are a wear item with a precise replacement interval, and using the right electrode material matters more than brand. Iridium and platinum plugs hold their gap for 60–100k miles; copper plugs spark marginally better but need replacement three times as often.

We compared 5 offers across major retailers for the 2nd Gen platform (2015–2026 2nd Gen). Prices range from $9.99 to $35.99 as of the last update.

Best picks

• Best overall: The iridium plug matching your engine's factory specification — same heat range, same gap, longest service life.
• Best budget: Copper-core plugs if you don't mind 20–30k mile intervals — they're cheap enough to replace often and conduct slightly better.

What to look for

• Never downgrade from factory iridium to copper on engines specced for long-life plugs.
• Buy the full cylinder count from one production lot — mixing plug states causes uneven running.
• Coil-on-plug engines: inspect the coil boots while you're in there; they're the usual failure companion.

SUV-specific note: parts often differ between two-row and three-row configurations, and cargo-area accessories depend on seat layout. If your model offers both, confirm which configuration the listing covers.
