❓ Quick FAQ

What makes these different from standard plugs?
A laser-welded iridium center electrode requires less voltage to spark, improving cold starts and throttle response, while a platinum ground electrode resists wear — together maintaining precise gap over up to 100,000 miles.

What does "IFR5E11" mean?
The "11" indicates a factory-preset gap of 1.1mm (0.044"), sized for standard coil-on-plug ignition systems.

How do I install these safely?

1. Let the engine cool, remove plastic covers, and blow debris away from the coil packs.
2. Remove the coil packs, inspecting boots for oil or tearing.
3. Extract old plugs with a dedicated spark plug socket, keeping the extension straight to avoid cracking.
4. Verify the gap with a wire tool (don't use a coin-style gauge on iridium).
5. Hand-thread the new plug in for several turns to avoid cross-threading — never use a power tool to start it.
6. Torque to 13–18 lb-ft (or hand-tighten plus 1/2 turn), then reinstall the coil pack and repeat for remaining cylinders.
