I bought them without even looking at them i was in a rush, I wanted copper because i don't mind replacing them, the car will be sold by the time I need to replace them. They are "Bosch Super" copper plugs, I noticed I may have gotten the wrong ones when I found out they were less than $1.00 each? The Rex/Product # on them is: 7556 or FR 7 DCX, are these ok to use or should I have spent the extra $$ on the Bosch Platinums? No I'm not a newb I am still running the 1 step colder NGK's from when I was sc'd and I am getting a little hestitation, that and they are 30K miles old The other Bosch copper plugs they had, had multiple tips but I don't recall any of my plugs ever having that so I went with these. Need to change them tomorrow before I go on a trip. Knowledge please...
Thanx in advance family.

 

No Bosch plugs....

Go return them and get NGK V-power copper plugs... they are only 2 bucks each and are the right plugs for your engine.
