Excellent spark plugs for 5.7 hemi
I used these on my 5.7 hemi for my 2006 Dodge Magnum and they work fantastic. Make sure to remove the spark plugs when they're cold so you don't damage the aluminum heads.

Totally disappointed!
The plugs didn't match the description, double Iridium, item is single. Very disappointed because plans had been made to install them this weekend.

Nice, consistently good plugs for my '06 JGC!
Went easily into my '06 Grand Cherokee with Hemi (16 total plugs). Purrs like a kitten, now. Does not require any anti-seize lube during installation, and specifically says so in the instructions; it's nice to not have to buy that. All of the old plugs were Bosch Iridium and came out easily. I decided to upgrade to the Double Iridium model, to "help" the older engine, approaching 140,000 miles. Drives nicely and idles more smoothly than it has in a long time. A little bit expensive compared to the Champions, but they should have a much longer service life, which is important for an older car that I will most likely be the one performing the repairs on.

Upgrade to Iridium
I installed a set of 16 of these spark plugs in my Chrysler 300C and have observed a noticeable improvement in the smoothness of the engine at idle. I believe there is about a 2 mpg improvement in gas mileage as well, but only at highway speeds. I have somewhat of a heavy foot in town, so my MPG has not changed there. These plugs are very high quality, and may last the life of my car. I highly recommend them.

Good Plugs
Great spark plug. Does not faul, stays clean. Have used it for years with no issues in Jeep Wrangler and Dodge Ram 1500.

They're spark plugs. They do their job nothing special ...
They're spark plugs. They do their job nothing special. No increase in HP no increase in MPG. Stop trying to push your voodoo on others. Only difference will probably be longevity due to the iridium.

Great plugs
I installed these plugs in July on my Dodge Charger. I have seen much better performance with the engine. I also get better fuel economy, 2-3 mpg improvement over the stock plugs!

Performs well
Put these in my Jeep Wrangler, noticed an immediate improvement in performance and MPG. Not the priciest plugs, but a good solid mid range performer for the price.
