Looks like original plugs
Changed out the plugs over the weekend hoping to solve some engine surge issues...the plugs could almost be original if they weren't mix and matched...some were wet even though it had been sitting for a day...the engine is a lot smoother but the surging is still there...I replaced the mix matched with Ac delcos...airfilter is new as well(K&N paper)
I've read here in the forums that it may be a loose intake manifold, MAF Sensor, TB? No codes and the only issue (knock on wood) this awesome machine had was a leak from the tranny cooler and it was a quick fix thanks to the local NAPA store...any other ideas or should I wait a couple more days and see if the engine straightens out with the new plugs working? Thanks!
How much tear down am I looking at to check the intake bolts??? Looking at the schematics there is a bit of removal...

after checking the forums about the engine surge there seems to be a few different possibilities...now looking at the one really corroded spark plug could a corroded COP be causing the surge? Before the spark plug change the surge was around the 40mph area and now it is up around 55mph...it clears up with a quick tap or release of the gas pedal...

1 could be a bad fuel injector leaking, try running some good fuel injector cleaner threw the fuel system.2 or a bad fuel pump with low fuel pressure rent a fuel pressure gauge and make sure you have good pressure, last thing 3 did you clean the throttle body butter fly and maf
