It is worth the price. You're not gaining massive performance but also not losing anything whatsoever. They spark faster/longer and are much more durable than other spark plugs due to the ruthenium element involved. Longevity Is better than other plugs as well. Time will tell. The plugs are likely not pre-gapped to the OEM specs of your car. If so, make sure you use a proper tool/gauge. Do not use the old style disc gappers as they destroy the precious materials.
