Do sparkplugs make a big diff in performance?

posted by  someone claiming to be Costas on  Thu May 9 17:15 CST 2002 [RELATED]

Will the certain typos of plugs give the car a different feel from others? or is it either they work or don't?

    I figure if plugs make a difference, Volvo engineers would figure it
    out and use them (maybe they do). They put it a lof of effort to
    squeeze out more power from the engine (example: going to variable
    valve timing in newer models and independent coils for each
    plug -- not cheap). It is a pretty good bet they have looked at plugs
    and already optimized it (assuming there is anything to optimize).

    Yes, use NGK glow plugs, it's the best and cheap too.

    Costas,
    Performance meaning more horspower/torque? No. Providing they are not fowled and are gapped properly, they allow the engine to run more efficiently resulting in better gas mileage and lower emissions. Manufacturers selling the idea of better perfromance is simply marketing hype. IMO
