Factory spark plug Gap?

Hey, I just replaced my spark plugs with the equivalent Denso, standard plugs. After I was done and driving around for a while, I realized I didn't even pay attention to gapping. I just put them in as they were. Should I take them back out? If so, how do you "gap" them, by bending something? Im hoping they already had correct gaps. By the way this is a 98 EX.

yes, you should take them back out and gap them... When I do it, I use a spark plug gapper that tells the measurements... a simple search yielded me this:
Engine Type Spark Plug(NGK) Gap
D16Y5 ZFR4F-11 1.1 MM / 0.043"
D16Y7
D16Y8 ZFR5F-11 1.1 MM / 0.043"
B16A2 PFR6L-13 1.3 MM / 0.051"
You have the d16y8, so you need to gap them to 1.1 mm or .043"... good luck!
Oh, and don't forget to put some anti-seize compound on them so they're easy to get out when you need to take them out again.

O I forgot to mention that when I bought them, they were specified for my car. So thats why I think they are already set. And they are Denso not NHK.

Ok? maybe too technical for this section.

if they are pre gapped for your car specifically, then, you dont need to gap it. if you bought a $.99 gap reader when you bought the spark plugs, that would of made things easier too.
not technical, a little common sense really.

95% of the time "pre-gapped" spark plugs are not gapped correctly. Always double check.
