I got some platinum plugs from auto zone yesterday and he said just to put them n since they are the platinum they dont need to be gapped? Is this true?

 

Maybe you misunderstood, or the guy is a moron. Spark plugs need a gap to fire across. The size of the gap is indicated on the emissions lable under the hood or in the owner's manual for your vehicle. Probably what he meant was, platinums and some others come pre-gapped for your application. A small cardboard sleeve around the firing end of the plug would imply this. It is always a good idea to double check the gap before installation.

 

what should my plugs be gapped to. I have a 00 Civic SI DOHC v-tec..prolly dont matter but got a cheap cold air intake and magna flow muffler.

 

??anyone know??

 

.030-.035

 

I just checked them yes they do have a cardboard sleeve around them.

 

When I put my new plugs in sat., the old ones that i took out were gapped to .056!

 

you should go w/ some denzo or ngk iridiums instead. much better plugs and they are oem. working at a shop ive seen cars come in running just fine and missfire like mad after we put in some platinum 4 plugs in.

 

Stick with the $1-$2 NGK spark plugs, they're inexpensive and do the job well. I don't know what motor your spark plugs are going in but the gap is most likely a .044.

 

STOCK 2000 SI CIVIC

 

the reason i say iridium plugs is because they last longer without problems. That being said, if you are like me you will change your spark plugs more often than you need to anyway, so that migt be a good bet. Ive never ran the regular ngk plugs so i cant tell you how they do. im pretty sure a b16 calls for iridiums however. could be wrong.

 

not stock here, .016 gap ftw lol

 

auto zone showed to run platinum take that for what its worth lol
