Please note that these plugs are properly gapped by RR Racing for your Lexus!

The IS-F Yamaha/Toyota V6 runs extremely hot under track conditions. We recommend upgrading to 1 step colder plugs. NGK Iridium are know to be the best quality Iridium plug you can buy. As an added benefit, NGK Iridiums are common to many applications, and are therefore more reasonably priced than the OEM Denso plugs.
