Will that cause detonation even with FMS 9mm wires?

My car still detonates the odd time. It used to happen when it was warm out, but then I cahnged my MAF and I was OK. Car didn't detonate at all in 90+ degree weather and then all of a sudden the lasl couple weeks it's been doing it again (temps are around 60-70 degrees).

I guess I could move them and see if it helps...
