what plugs are you runnin?

[bowtie-till-i-die]

Just like the title says, what year, engine, and plugs are you running? how do you like them? Im running the E3s and not sure if im to cracked up about them. I used to run Bosch Platinum 4s and my truck realy liked them. I got a 98 4.3 btw

I have a 98 with the 5.7 and I've been using Bosch Platinum 4s. I love them and they seem to last a long time. I started out with platinum 2s and then went to 4s. One of the good things is that you don't have to gap them. I've been thinking about E3s, some seem to love them and some seem to like them but say they don't last as long. So I'm not sure if I will try E3s or not. If they don't last as long then any gain you get with them isn't worth it if you have to replace them more often. I also grab Bosch plugs when I get new plugs.

i use NGK TR55's.

1996 C1500 with a stock L31 Vortec 350
1994 C1500 with L05 350, Vortec Heads, Comp 287 Cam, Carb, etc

E3's are a joke.

Gapped to 0.035, seem to work well with the Whipple.

94 with a 5.0L, running autolite platinums, Haven't had an issue yet. I run the E3's in the Monte and they work great, I'm going to try them next time around

Same. '99 5.7 running NGK TR55's gapped at .060. Always ran smooth as silk with them.

'92 K1500 5.7. Got sick of constant gap problems...have infamous Bosch +4's, been perfect for months now. And I'm a proponent of AC Delco stock plugs though.
