About these plugs
DENSO Iridium Power plugs are DENSO's performance iridium line. A 0.4 mm iridium center electrode fires with very little voltage, and DENSO's patented U-groove ground electrode leaves room for the flame kernel to grow, for crisp throttle response and smooth running.
- 0.4 mm iridium center electrode: DENSO's iridium alloy, one of the finest center electrodes made, for a strong, concentrated spark.
- U-groove ground electrode: a groove cut into the ground electrode lets the flame front spread instead of being smothered.
- Performance heat ranges: offered in a range of heat ranges, so tuned and stock engines can run the right one.
- Durable iridium alloy: resists heat and electrode wear.
- Where they fit best: drivers who want better response from a stock engine, and modified engines.
The plugs come gapped at 1.1 mm (0.043 in). Check the gap your engine calls for before installing.
Electrode tip: Iridium Power. This plug has a 0.4 mm iridium-alloy center electrode with a U-grooved ground electrode. The fine tip needs less voltage to fire, for quick, reliable ignition.
Match your engine before you order
This set of 4 is for the 1.8L 4-cylinder 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.
Note: DENSO lists more than one plug in this line for some of these engines (heat ranges 16, 20, 22). 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.

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.
