5224's. Thats the direct replacement for the OEM plug. There was a noticable difference over the worn out Champions. But I don't know when the last time they were changed was. I put about 20k miles on the them and the previous owner might have put a lot more on them. So it was definitly time...

the ones i pulled outa my truck were 5224s and they were worn. It was running ok, but i had been having some bad gas mileage problems. I put the 3923s in yesterday and im gonna go fill up my tank and see if there is a diff.
ive heard mixed things but i guess platinum core ones make the engine unhappy. Ive heard good things about these 3923 copper core ones. But we will see!

Last night I decided to install my intake and figured I should do the plugs while everything was out of the way.
The rear plug on the passenger side of the engine was the toughest one to get to. I chose to do that one first since I would need two u-joints on either side of my extension.
My plugs were also worn with the gaps in them over double what they were supposed to be. HUGE difference now that I changed them.
Bit of advice: 1st) I kept a vacuum handy and sucked up all particles before I took my old plugs out to make sure nothing fell down int there once I removed them. Then I vacuumed adjacent areas again before putting new ones back in.
2nd) My spark plug socket was brand new and, as a result, the rubber padding inside of it was extra anxious to do its job. Unfortunately, it did such a good job, that the socket would stay on the plug and my extension would pull right out of it, leaving the socket in the hole with the spark plug. Because I have coils that reach way down to the spark plugs, the socket was unreachable. So I just unscrewed the spark plug again to get my socket back. Then I used a phillips screwdriver and wore down the rubber a bit so that it would allow the socket to release the plug.
