Tell me what you think about these 2 products:

[nonovurbizniz]

dude that doesn't sound like overkill... it's sounds like you have serious mental or engine problems.

if your plugs are even close to being in need of a change at 3000 mi then your engine is shot.

if you think your doing yourself or your car a favor by changing them that often... your wrong.

stop waisting money you could save that and change your plugs every 40k (still WAY too often).
