Spark plug help C55

I've always used Bosch plugs/wires but want to try out ngk. I purchased ngk wires but now having some trouble with the spark plugs. I don't want any fancy spark plugs. I usually go for for plain ol' platniums and I really like them. I found some ngk plugs (part number 7092) I've looked all over online for these and can't seem to get down with it. Some of the ones I've looked at say "G-Power Platnium and other just say "Platnium" I would figure they're the same but some listings on eBay say they'll fit and some say they won't.

http://m.autozone.com/external-engine/spark-plug/ngk-gp-platinum-spark-plug/505373_0_0/?cmpid=PS:3:3:1&s_kwcid=AL!5142!3!105136219239!!!g !54514597379!&ef_id=WOIAXQAAAOI8j2Iy:2017040308284 3:s# AutoZone says it fits

https://m.summitracing.com/parts/ngk-7092 Summit says it only fits 06 models

Really confused at this point. If anybody has any answers please shoot me a reply. Thanks!

Prefer to go with copper core "C55/Clk55/Slk55" OEM/NGK IR plugs, #: "003 159 97 03 ",,

they're really great..

agreed! Copper will always be better. I wanted platniums for a little bit more life but I might go with the coppers. By the way what is the ngk part number for those

As i know;

there're 2 NGK #s;-

(IFR6D10) & (ILFR6A)

just be sure to get a copper core,

NGK has a differ production line, with same part #, that comes with alloy core not copper..!,

but if you get an OEM's, they will come with a copper core for sure..

The best thing you can do when attempting to verify fitment is to use the manufacturers product guide. The short answer is absolutely, the 7092 plug will fit. The resource I used was http://www.partcat.com/ngk

My recommendation is similar to the others, typically copper core or iridium offer the best performance.
