About these plugs
DENSO Double Platinum plugs put platinum on both the center electrode and the ground electrode. That matters on waste-spark (distributorless) ignition systems, where half the plugs fire with reversed polarity and wear on the ground side: platinum on both sides keeps the wear even and the gap steady over a long service life.
- Platinum center electrode: resists erosion and keeps the spark stable.
- Platinum-tipped ground electrode: made for waste-spark systems that wear both electrodes.
- Extra-long life: holds its gap far longer than a nickel plug.
- OE-style design: matches engines that came with double-platinum plugs.
- Where they fit best: engines that call for double-platinum plugs, especially waste-spark and coil-pack systems.
The plugs come gapped at 1.1 mm (0.043 in). Check the gap your engine calls for before installing.
Electrode tip: Double Platinum. This plug has platinum on the center electrode and a large platinum pad on the ground electrode, which cuts wear on distributorless (waste-spark) ignition.
Match your engine before you order
This set of 6 is for the 3.6L flat-6 engine (Porsche 3.6L turbo flat-6; Porsche 3.6L flat-6) 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.
Note: DENSO lists more than one plug in this line for some of these engines. This set is heat range 20. Match the plug you are replacing, or send us your VIN and we will check.

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.
