Go Denso
Staff Reviewer -
These plugs made my cobra mustang run alot better so I tried them in my everyday driver 05 Focus and now it runs alot better also. Just be sure and gap them at factory specs.I am suprised that they perform that much better than the NGK Iridiums that came stock! You will not be disappointed.
Bottom Line Yes, I would recommend to a friend

Finally changed the plugs in my Honda Civic, over 75,000 miles. I used the Iridium Power plugs and what a difference I could feel in the car's performance. I checked the gap as I took them from the box but they were were gapped perfectly out of the box. Very easy do it yourself project.
great tune up!!

I only have 25 miles use on them and noticed immediate improvements in idle and highway driving on a 2.0 liter 4 cyl. 5th gear on my car has much better acceleration. I can attest proof positive that the Denso IK16 Iridium has improved my engines performance enough to be noticed and not subtle. I have never noticed this much improvement changing spark plugs on a car till now !

Great in the beginning
I bought these plugs for a Pontiac G6 GT to liven it up. In the beginning they were great with a large difference in acceleration. However within 700 miles on the plugs this performance increase started to dive downward. My gas mileage went from 25 mpg to somewhere around 16 mpg with only about 2000 miles on the plugs. I currently am looking on the site for the stock delco part number to get my gas mileage and performance back. Right now with 2500 miles on the plugs my car has a rough idle, which will be gone once the Denso's are out! (Use them for race day and then take them out and reinstall your factory ones) For the price they are per plug they should last more than 2500 miles.
Bottom Line No, I would not recommend to a friend
