What kind of spark plugs are the best for a 95 integra LS. I have heard to use copper, but I have bosch platinum 4's or whatever now. Are they bad? Whats the difference?

 

stocks

 

Why though? Doesnt platinum conduct better? Surely there is an advantage into having 4 spark prongs(whatever they are called)

 

Agreed.

 

*sigh* No facts to back up your suggestions.

 

Unless you have upgraded your ignition system, there is no need to stray away from stock plugs. The difference between one set and another is how often you change them and of course the material they are made of.

so should i just keep my platinums in their until they go bad??

 

Unfortunately, there is no single answer to this question. As spark plugs grow older, they lose their sharp edges as material from the center and ground electrodes is slowly eroded away. As the gap between these two points grows, the voltage required to bridge the gap increases proportionately. Even the best ignition systems will be strained to supply enough voltage to completely burn the fuel. It is at this point, when fuel is being left unburned, that the time has come to change spark plugs.

Replacing worn out spark plugs with new ones (with sharp new edges) effectively restores the ignition system's efficiency. Misfires are reduced, power is restored, economy of operation is enhanced and emissions are reduced.

 

ok, so in theory the "quads" should last longer, because once one starts to wear a little it will arc to another??

 

I honestly don't know how these "quads" operate.

 

Ok, you know how in a regular plug there is one, we'll call "finger" that comes over the top. Well on a quad it has 4. Looks like:

Thats a top view, and the electrode is in the center

 

well, more like a cross hair, it didn't post quite right

 

the bosh +4 plugs are the way they are so you dont have to gap themthey automatically spark off the closest gap to stock just get some ngk-r plugs and shaddup

 

wrong, they are all gapped the same. Have you checked? Obviously not. Check it.

 

NGK. all the other ones suck.
