You should always check the gap before you install one. They are ususally right, but over the years I have had a few on other vehicles that were incorrrect out of the box, and I had to adjust them.

My manual says .030. And i've never got a plug that was at the right gap.

speedyquad is pretty much right. It is .024"-.028" for the standard DR8ES-L plug, and it's always good to check. Though, a manual is a great thing to have. And as always I suguest EBAY, for best price.
