Spark plugs and detonation!!!
 

Hey everyone!
I have a '90 with the Greddy kit no intercooler and I have a nasty case of detonation. The only mods I have are:
greddy kit
jackson racing fuel pump
Air/fuel

Someone told me that colder plugs would help, any suggestions?

hm... timing retard usually helps :)
what do your afrs look like when in boost?

I'll have to check the timing again, it's retard to 3 degrees?
I don't have a AFR gauge so I don't know. The mix seems fine when looking at the spark plugs

6 degrees.

Thanks!
Any suggestions for a spark plug? When I went to autozone they had no idea what I was talking about when I said a "colder" plug!
