FREE SHIPPING. Denso's Iridium power spark plugs help your vehicle achieve unparalleled performance. It alters the belief that a mere spark plug can add power and mileage. This is done by combining an ultra-fine 0.4mm diameter Iridium center electrode with a tapered cut U-groove ground electrode. Iridium conducts electricity better than platinum, however what makes it exceptional is it's also 6x harder and 8x stronger than platinum. Because of this, the center electrode can be machined down to 0.4mm.

| 2010-08-22 Eric .... | Gr8 plugs. Changed at 40K miles, should have done it much sooner. My engine feels/sounds much healthier, No more rough idle(even with the A/C on)!! FYI, If you have an AP I suggest regaping them to .029 |
| 2010-05-30 Hudson .... | Great plugs. Got mine replaced at 13k and car is running much richer as a result. Was running 11 AFR on WOT, now I'm running 10.2 and still putting down the same power. |
| 2010-03-26 Hector .... | Replaced my stock plugs at 24k miles. Start up is smoother, smoother acceleration, and no hesistation! |
| 2009-08-18 Hector .... | Replaced the stock plugs with these at 28,000 miles. Acceleration is smoother, no more random hesistation, and better gas mileage. This made such a difference on my mildly modded 08 MS3. |
