What plugs do you 4.9 owners(past or present) prefer to use?

use AC Delco double platinum spec'ed for a '95 4.9

I currently use Bosch +4, they seem fine.

I have made 140.000 miles with original regular ACDelco plugs. Car has been running just fine. You can buy them at Adavance Auto Parts for $16 a box (8 plugs). Replacing the plugs on 4.9 is not fun at all.
