Comments about Denso IK20 Iridium Power Spark Plug:
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.

Awesome plugs for my 94 Integra GSR. I waited to put two full tanks through before writing my review and so far I've noticed 1-2 mpg better gas mileage! I feel a difference in throttle response and the car just seems to run better!

Comments about Denso IK20 Iridium Power Spark Plug:
The Iridium Technology is a great step up from any other plug out there as far as "performance goes".
That said' They only last about half as long as Double Platinum plugs. According to Denso, Iridium plugs should be changed at around 30,000 miles compaired to over 100,000 miles on Double Platinum.{IF YOUR CAR HAS NO FOULING ISSUES}.
If peformance is what your after buy them. If your plugs are hard to change or it costs you alot for a mechanic to install them get "Double Platinums" and forget about changing them. Not regular cheaper platinums they wont last very long.
These Iridiums are said to add 2-3 hp in stock engines and 20+ in supercharged/turbo engines. The later is very hard to believe for me but Denso's sight states it. I'd have to see a dyno?
