You read that wrong...."AL606's, and AL605's are basically for stock cars or very small bolt ons still running the stock S/C Pulley or modded N/A guys"Ok that post says i can upgrade wires from zzp but since im not increasing compression i wont need anything more than 606 plugs. Did i read that post link correctly?
Found it "N/A guys...you want to keep a hot spark. NGKTR55/AL104's for your 3.4" Setup"
