As a temp solution it 'might' be OK for some cars but at least 2 folks with my engine have had issues running NF booster causing plug tips to fail (looked eaten away) so I'd prefer not to even risk it after just getting my engine rebuilt![]()
Strange. In my case, and for many people I know running highly modified engines, we run NF in every tank without issues My spark plugs are NGK R7437-9 Iridium. Different engine completely of course but runs 140ps per cylinder at 2.4bar so they do take a beating.
