After taking out the plugs they were brown all 4 cyls I replaced them with NGK lasers and wow my car was so much more responsive and it would ride through every gear through high rpm without power cuts or jittering.

Pros: more responsive, no power cuts

Vehicle: Volkswagen

If you are having misfires under load, the first check is always ignition, i.e. spark plugs and coils (only factory coils and factory or NGK plugs in my experience).

Pros: factory coils recommended
