Best spark plugs for motor with over 100k miles. Motor is stock. Putting long tube headers and y pipe on Saturday.So might as well change the plugs.

TR55's unless your running high compression or spraying. then you need to step up to TR6's. running TR6s in a stock compression motor is not a good idea. not a bad one, but there are better methods. the combustion chamber temps will not get hot enough and the fuel will not burn as completly as it would with TR55's
