The ISX/GSX Toyota V6 runs extremely hot under track conditions. We recommend upgrading to 1 step colder plugs. We tested the Brisk Silver plugs extensively, and we highly recommend them for our supercharged applications. This product includes 6 plugs.

Please note that we sell a different Brisk Silvers plug for NA applications.

  • These plugs are 1 heat range colder than stock
  • They use a non-projected electrode which we find works better than an OEM type projected electrode on the track, but works equally well on the street.
  • Silver is the best conductor of any metal! It conducts 560% more electricity & 481% more heat than Platinum, and 276% more electricity & 177% more heat than Iridium. Silver spark plug electrodes transfer electricity & heat better than any other spark plug material resulting in the most powerful spark! This is beneficial for a full complete combustion of the available fuel and air in the combustion chamber, combustion efficiency creates horsepower gains.
  • This spark plug is the best recommended spark plug with our supercharger kit for Lexus IS-F

The disadvantage of these spark plugs is that they last less than the NGK plugs we sell -- about 20,000 miles.
