R33 - RB25 - Currently working towards increasing power to 450bhp - can anyone help me re spark plugs - not sure what size to go for as it seems you could use 7, 8 or 9 with an RB25 (i think!) - is any one of these better or another size altogether? And would anyone recommend a particular make being better than any others. Any help would be appreciated
Thanks
