Hi All,
Just fitted Boosterplug to 2018 Classic c5 E4. For me with my particular machine it has made a percepible difference to 'rideability'. The bike does not appear to be any quicker or more powerful, however the low speed partial throttle performance feels a lot better. The spark plug is a BPR6EIX and plug readings indicate a better burn with the Boosterplug fitted. Fuel consumption appears not to have been affected. So, hopefully without triggering an avalanche of discussion about stoichmetrics/PCV's/rolling roads/snake oil etc, I can say that for me Boosterplug was a cost effective and worthwhile addition to a bike that was already a truly enjoyable ride. If in the future I was to consider cam changes, bigbore kit, I would go for a sophisticated processor based unit such as PCV or Powertronic. The Boosterplug seems to cope very well with the modest muffler, downpipe and airfilter changes I have made. I'm off for another ride round the lanes down to Salisbury, Ride Safe!

I installed a Booster plug on my 2019 Interceptor (INT here in the US).
Stock the bike is tuned rather lean and with a muffler (silencer) change and air filter upgrade low speed throttle input became even more imprecise and lacked crispness when blipping the throttle during down shifts.
The booster plug made a definite improvement.
I also noticed slightly stronger acceleration and midrange.
I placed the probe at the mouth of the intake tract....if that helps.

Hi all,
Sorry for late reply, life n'all that. After removing air filter, I zip tied the Boosterplug temp sensor to the air filter mounting bracket ('> ' shaped)in the centre of the air filter on a small piece of rubber pad as a vibration damper, passing the cable through the fresh air ai intake horn, then refitted air filter. This was easy, quick and within the boosterplugs fitting parameters. Hope this helps.
