i have heard mixed feelings from many people about plasma boosters. My decision was that the plasma booster not worth it based on what i have read and peoples impressions of the system on their cars.
I have it on my car..Don't know if it increases power..I have DensoIT20's gapped @38 and checked plugs @8200 miles and they looked perfect..I now have 10k miles on the setup without changing or re gapping plugs..
I should try next time at dyno to disconnect the PB and see if there is any change..
