I gapped these to .060" (they were .040" out of the box). Should I regap to .040"? I installed these in a 2000 Chevy Silverado, 5.3L.

They come gapped that way I didn't change mine install on 2005 Tahoe runs like butter

So you get 1 plug correct??? Not 1 pack of 4 as the picture is ever so coincidently falsey misleading the representation four pack as as picture is

Correct. 1 quantity = 1 spark plug. I thought that 1 quantity = a pack of 4 spark plugs as the picture suggests; but after receiving my order, I found out that you only get 1 spark plug. I agree with you! The picture is very misleading and needs to be changed to clarify that you're only receiving 1 spark plug per quantity.

How many are in this pack?

1 spark plug. The picture is VERY misleading, as it shows a pack of 4 plugs and 4 single plugs in front of the 4 pack. So 1 quantity =1 spark plug.

Some deliveries may take a little longer than usual due to regional shipping conditions.
