About these plugs

Bosch Platinum+4 plugs use surface air-gap firing with four ground electrodes, so the spark has several paths to jump. They reach self-cleaning temperature quickly for easy starts and smooth running.

  • Four ground electrodes: give the spark good access to the air-fuel mixture.
  • Surface air-gap firing: multiple spark paths for a strong spark over a long life.
  • Factory-set gap: never needs adjusting.
  • Copper core: a broad heat range that resists pre-ignition and fouling.

The gap on the four ground electrodes is set at the factory and does not need adjusting.

Match your engine before you order

This set of 12 is for the 5.4L V12 engine in the vehicles below. Many of them were also sold with other engines, which take different plugs. Not sure which engine you have? Send us your VIN.

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.

Installation

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.

Your eBay protection

These terms apply alongside eBay's policies. Nothing here limits your rights under the eBay Money Back Guarantee or under the law.
