 long lasting July 19, 2010
T. Pham (AUSTIN,TX)
I have been using iridium since 2001 on my civic. I saw quite a few comment about lifespan of the plug.
My denso iridum on the box said good for 250000 miles, and my civic is at 260000 and still running swell.
So they do last long, unless they reduce the quality so denso can make more $$.
don't hesitate to buy this one July 11, 2010

If you look for quality, don't hesitate to buy this one.
Frankly, when I fixed it (all pack) I felt that my car's engine worked smoother.
Best spark plugs June 25, 2010

I tried some slightly lesser iridium ones in the past, but this one beats them all. For both of my cars (a Nissan and a Suzuki) the engines instantly ran/sounded better. The Suzuki ('04) hasn't really shown any improvement in the gas mileage, but the older Nissan ('97) now gets about 2 miles more per gallon.

I have used those spark plugs in my 2008 Chevy 1.6 L Aveo with 10.000 miles. I have noticed that the engine runs smoother. I haven't made detailed counts but I think that the gas millage doesn't increase significantly, but yes It does
Awesome deal on high quality plugs! April 27, 2010

I recently bought a set of 6 Denso IK20 Iridium spark plugs for my girlfriends jetta vr6. They were a direct replacement of the oem's and installed smoothly. The car desperately needed a new set and now runs great. Awesome price and free shipping is nice too.
