I may be buying some plugs for the max while i am having it apart. Is there any Power differences between the coppers and the platinums? I really want the platinums, but my cash is gonna be short after the transmission install, so i don't know which ones to get? one more question-I have a set of maxspeeds sitting in my floor that i really want to put on, and my dad is offering to help do them as well, but i don't have any new struts. What do i need to change to get the maxspeeds on my stock struts? will i need to cut my bumpstops or anything? My car has 122k, is that gonna be a factor in this with the springs? how rough will it be?

 

The only difference between platinum and copper plugs is how long they last.... Coppers last about 30,000 miles, and platinums last about 60,000 miles..... Copper plugs do provide a better spark though...

Also, if you are going to replace your springs, I would go ahead and replace the struts as well..... Stock struts wont last very long with lowering springs....

 

What are the part number for the coppers and for the platinums?
