Fitment: 89-02 Nissan Skyline GTR R32/R33/R34 RB26DETT

Details:

The NGK Iridium plug is a great replacement for the stock plugs for the RB26, and are one step colder than stock, generally good up to around 500hp. These come pre-gapped at 0.044" (1.1mm) but we recommend double checking the gap and gapping down as necessary for higher boost levels.
