Knock Questions

So I had my buddy bring his scanner over to scan for knock, I thought I'd check it after all the plugs, wires, and coils I put in. Under normal conditions knock sat at 0. It came up to about 4 degrees at wide open throttle at around 50-60mph.

Can you tell me exactly what that means? Is that good? Bad? If its bad what's the best way to improve this?

Just as a reminder here's what I have. (I will update my sig with this now.)

180* T-Stat
PCM
CAI
3" DP w/U Bend Delete
2.5" Magnaflow Cat Back

I just put in all new coils, AC Delco wires and went with NGK Platinum stock heat range plugs. I did that because I was having the sputter issue and now its cured. Should I go back to my Autolite 104 copper?

Let me know what you think...
 


Holy hell. Thanks for all the info.

Are the 606 or Delco stock heat range? Or am I looking for something a range colder
 
AL606 and Delco's are stock heat range.

Our cars, with the blower, love the Copper AL606's, but they need to be replaced every 15,000~ miles.

Like Cam said, remove the Platinum plugs and put in the 606s or Delco Iridiums.
 
sorry to thread jack but i just installed my scan gauge ii yesterday, and ive been watching my knock. it has sat at 0.0 for a long time even during wot. until later that night i got 1.5? im all stock. bad reading or just cuz its stock and freezing temps in chicago?
 


colder the air, the more dense, the more boost from your SC. Either that or your knock sensor wasn't one. Usually its on either have such and such mins or temperature of the car when its warmed up.
