No. Unless your old plugs are fouled and worn out. A spark plug is a spark plug. The expensive ones are just used for longevity. Just get some NGKs and be happy. (if you have a modded car it is a different story)

If you want cheap improvment, change your air filter and make sure you tires are properly inflated.

 

thanks i didnt think they added any hps. and ya i was thinking about just buying some ngk

i found the answer to my own question... figured id post what i found


In most cases, it is not until the engine is modified, or the compression is raised significantly, that stock ignition systems and spark plugs begin to show signs of being inadequate. At this point, a variety of factors determine which spark plug will be best suited for a particular configuration. In these modified engines, specific electrode/tip combinations, electrode materials and colder heat ranges can provide measurable gains in power. If your vehicle has had extensive modifications, it would be best to seek the advice of the manufacturer of your vehicle, the aftermarket supplier who manufactured your modifications, or your mechanic.

 

yeah, maybe a different heat range, i put split fire quadruples in my civic
