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