Go Denso
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.

better off with oem
Bought 6 of these plugs for a tune up on my 06 impala, after only 1200 miles on them the idle is rough and my gas mileage actually went DOWN(and yes I double checked the gap to ensure it was correct). It isn't a coil pack issue, I replaced the multi shortly after replacing the plugs(new ACDelco multi).Pulling these out and getting Delco iridiums. Best to stick with ACDelco for GM's

pretty quality spark plug, Denso is quite pricey so look for when on sale, but you get what you pay for and plugs are pretty good, no misfires, even under 17lbs of boost. i think i'll stick with this plug over my previous ngk's, and all 1.8t and 2.7t owner make sure you gap these plugs properly to your car!!! bolt down coil packs use .27gap all newer push down coils use .38-.42 gap. coming from long time vw/audi owner and enthusiast -2000 Audi S4 v6 twinturbo stage 3
Bottom Line Yes, I would recommend to a friend

Bottom Line Yes, I would recommend to a friend
excellent plugs for my Tiburon gs
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 !
Bottom Line Yes, I would recommend to a friend
great product
