decided to change my plugs in an attempt to fix a hesitation & "bass drum" sound in my '91 motor. i have acquired the the ngk plugs from courtesy distributing (909.679.7146...$11 per plug...best price around; thanx NSX Prime) and was wondering if there are any tricks or "issues" i should be aware of before i begin.
thanx in advance.
