About these plugs

DENSO Iridium Long Life plugs are the OE-type iridium plugs DENSO builds for automakers. DENSO is the original equipment supplier for many of the engines these plugs fit. They pair a fine iridium-alloy center electrode with a platinum-tipped ground electrode, for the long service intervals the factory calls for.

  • OE-type design: the same style of plug many engines came with from the factory, so it matches the original spec.
  • Iridium-alloy center electrode: a fine tip that fires easily and resists wear.
  • Platinum-tipped ground electrode: precious metal on both electrodes, for even wear over a long life.
  • Long service interval: made for the extended change intervals in modern maintenance schedules.
  • Where they fit best: engines that came with long-life iridium plugs from the factory.

The plugs come gapped at 1.1 mm (0.043 in). Check the gap your engine calls for before installing.

Electrode tip: Iridium Long Life. This plug has a fine iridium-alloy center electrode with a platinum-tipped ground electrode, the OE-type design built for long service intervals.

Purchase terms

Confirm fit before you buy

Check the compatibility chart with your full vehicle details: year, make, model, trim and engine. Catalog data can't cover every option package or mid-year change, so if you're unsure, message us your VIN and we'll check it before you buy.

We recommend installation by a qualified technician, following the vehicle manufacturer's service procedures and torque specifications. Damage caused by incorrect installation, such as over-tightening, cross-threading or incorrect adjustment, isn't covered.

Returns

Returned parts must be new, unused and uninstalled, in the original packaging with every piece included. A part that has been installed, modified or damaged after delivery can't be accepted unless it has a manufacturer defect.

If a part fails

Message us through eBay with your order number, a short description of the problem and photos. We'll handle the warranty claim and may ask for the part back for inspection.

Labor and other costs

Our responsibility is limited to replacing or refunding the part. To the extent the law allows, we don't cover labor, installation or removal, diagnosis, towing, rental vehicles, or incidental or consequential damages.
