im going to order a set of the super turbo racing ones and compare them to bkr7es when i dyno my car
last year in long races i also had some ignition breakup at high water temperatures (102+ degrees C) so we’ll see if these plugs truely are better
SG with the help of U2N is planning to test a few different things on the car this season, in the near future these spark plugs and a greddy intake manifold
