Precision EFI has sourced and tested a very high quality, direct replacement spark plug for the 900 ACE Turbo. These are made by a company that specializes in high boost spark plug technology. The issue with the OEM NGK plugs is they are fine wire type which tends to suffer from plug gap growth at a high rate.At stock boost pressures, this is normally not an issue, but with any tuning, misfires can become problematic. The Brisk plugs have silver core technology which will tolerate a tight gap that lasts far longer than the OEM plugs. We gap them in house so when the plugs arrive, they are ready to install.
