Re: [Honda-C70] New performance spark plug


If you mean the two listed in the Honda parts book, the performance plug runs a little colder
because the motor is turning faster, thus as it has less time to cool down they list a colder plug.
If you mean you are running a special plug like iredian then it is because the plug firing end is
out in the open and the fuel can get closer to the firing spark and it ignites the mixture easier.

Subject: [Honda-C70] New performance spark plug

Just got a new spark plug special ordered from O'Reilly, & I swear I'm accelerating just a little bit faster. Then again that probably also has something to do with my old dirty spark plug backfiring...

Does anyone know exactly how the 'performance' spark plug listed in the service manual does that the stock doesn't?
