Anyone using Autolite 104's? Good experience with them? I have a set of them, but have heard that the Race version would be a better plug to use. So is anyone using them with success

 

I've always had my best luck with the plain 'old Autolite 104's for a plug that works we'll NA, and on the amount of bottle I run......I've tried pretty much everything else out there, but always end up going back to them...

 

I'm running 104s...TR6s seem to foul out very shortly, and the screw on caps are a pain in the ***. My 104s always look great when I change them.

 

yea seems like there is mixed reviews from different people. i think i might go with the autolies as well. Isnt the autolites a shorter plug in size?

 

I've always ran the Autolite 103 or 104 without any issues. Cheap and effective.

 

103s and 104s here too without a single issue. Cheap, easy to get, and they work. Can't beat it.

 

Ditto... I use 103's and 104's.

 

What gap do you like to run with the 104's???

I can't wait till the track opens up.

 

Running NA (500flywheelHP), with the 104's at 0.040". Small shot of nitrous (635HP).... 103's at 0.035". Big shot (800HP total)... Champion S57YC at 0.028 - 0.030". Ignition system is 8 LS1-style coils.

 

What Fred said.

 

So I should put my 104's to around .030 to .040 for a 150 shot? I have a delteq system if that makes any difference.

 

.035 Imo.
