Hi All,
I've been using nothing but NGK plugs for a few years now and have never had a problem with them. I've tried using cheaper no name brand plugs and they were definitely hit and miss. As for price i was paying $20/box (10 plugs) for cheapies and pay $30/box for NGK through my local Repco dealer. Yes, $30, it took some negotiating but that's what i pay for BM6A or J19LM's. Champion plugs are marginally cheaper but i've lost confidence in them.
