Need recommendations for new plugs..

[BlueCoupeRedVert]

Well, I tried to get the Coupe inspected today and it did not pass.
HCs are through the roof. The car has been sitting a lot for the last
three years, only driven about 600 miles. It needs a tune up. so..

90 stock 5.0 and heads
e-cam
cobra intake
36lb injectors
83mm mass/ 75mm T/B
Old ass SN89 Paxton making about 7lbs.
shortie headers
bassani x pipe w/ gutted cats.
stock a9L comp/tune

As it sits now, three years ago it passed.

Thanks

Change the oil, go beat the crap put of it, get it warmed up, and try again..

If you do have to change plugs Autolite 3925's gapped to stock (.050) will work fine.

Yes I know this, but would still like to change/upgrade plugs.
They are like 10 years old.

i pulled one of mine, and I have Autolite 4525s. It looked good, nice and golden brown. So I start checking the rest. All on the drivers side looked great. Start on the passenger side and WTF! One of the plug wires was off. Jesus, what a dumb-ass thing to see. Clean the rest, check all the plug wires, cap and rotor. Start it up. Runs great, no miss, quick throttle response. Take it for a quick trip around the block, big difference. lol
