Spark Plugs for the Toyota Alphard – Performance & Replacement Guide

Spark plugs are essential for keeping your Toyota Alphard's engine running smoothly. They ignite the fuel-air mixture in the combustion chamber, and over time, they wear down—leading to poor performance, misfires, and reduced fuel efficiency.

When Should You Replace Spark Plugs?

For most Toyota Alphard models, it’s recommended to replace spark plugs every 30,000 to 60,000 miles, depending on the plug type (copper, platinum, or iridium). Always check your engine code and service history for specifics.

Signs that your spark plugs might need changing could include - engine misfires or rough idle, difficulty starting the vehicle, reduced fuel economy, hesitation or sluggish acceleration or an engine warning light.

Using fresh, high-quality spark plugs ensures reliable ignition, smoother running, and better fuel efficiency—especially on larger V6 engines commonly found in the Alphard range.

We supply OEM-spec and upgraded spark plugs for Japanese imports, with correct fitment for both petrol and LPG-converted Alphards.
