They look impresive on the Cobras 20+ rwhp.

 

well they are expensive and cobra (and most of the svt lightning guys) enjoy to waste money in their cars. i wouldnt put one in my car. those brisk and denso plugs have issues with teh tips breaking off. i would stick to ngk's and go and spend the rest of the money on a nice dinner

as for 20+ rwhp.. lol, ranks up there with teh K&N airfilter claims
