Hey all i recently changed the spark plugs on my dads Cavy and it made a world of difference. I dont know when the last ime was when my car had new plugs so I am going to do it this weekend. Which plugs worked out best for you and what did you gap them at? Thanks TaZ

I use one range colder plugs b/c I'm juicin'. They're NGK BKR7E-11 gapped at .040, but NA engines should have BKR6E-11. Some folk are running BKR5E-11 (hotter than stock) plugs and like them.

ummmm.... a spark plug creates a spark in the combustion chamber to ignite the fuel in the power stroke. doesnt really increase anything unless you got bad or old plugs replacing them will definitely burn the fuel better. hotter plug you'll burn more fuel
