If I were to order a set from the NGK web site, would they come pregapped and ready to install? No doubt, I would still double check the gap.

 

I have heard alot of people on here claim that they come pre gapped and that they just take them out of the box and put them in the car. I double checked mine anyway, and a couple were off, maybe from shipping or storage, so I dont think it will hurt to double check. They do claim that they are pre gapped and ready to go though.

 

A gapping tool sells for a few bucks, $5? Every car part store carries them. They last for life. I suggest just buy one...

 

yes the maxima comes pre-gapped so no worrying. why order? why don't u go to ur local parts store like advance auto where i got 6 for around $10.

i just took out the old ones and hand tighted the new ones.

 

It is better to check them b/c I have seen them be WAY off before. A gapping tool is a really good idea.

 

Technically they do, but check 'em anyway. I think the circular gap tools are like $.99

 

how tight should u turn it before its okay?

 

Turn what?
