and 1200cc- Speedmaster/Bobber/T120/Thruxton/Thruxton R/ Speed Twin

Just email us your model/yr when ordering

Modern EFI bikes especially Euro 4 run very lean in open loop mode and this can cause stalling, poor running and hesitant acceleration.

This fuelling device interrupts the signal from the air temp sensor and modifies it to make the ECU add approx 4-6% more fuel during acceleration in open loop mode, it will not affect MPG as it has no effect in closed loop mode ie. cruising mode or steady running. The device has its own temp sensor and it modifies the signal to release the correct amount of fuel for the measured air temperature.

Very easy to install with correct plugs ( PLUG AND PLAY ) no wire cutting required. It has a no quibble money back satisfaction 60 return and a lifetime product limited warranty

    My Street Twin has a Tec X Pipe and a K&N, so the Booster Plug has smoothed it out a lot – doesn’t seem faster but much nicer to ride. Piece of cake to fit – 10 minutes?
    Plan is to ‘open up’ the baffles; and a Tec cam has just arrived in the post. Watch this space!

    Make the machine run much smooter. Make a big change.

  3. Leslie C.

    Will be fitting fuel booster plug during the winter months along with tec x-pipe and Trident silencers… so can’t give feedback yet.

    It takes only a minute to install, child’s play. Made it more lively up to 3500rpm. You can feel the difference.

  5. Jimmy N.

    As already said : very easy to fit. Make the bike run smoother so much enjoyable.

    Fitted in conjunction with K&N filter & X-pipe on 1200 Thruxton R and has smoothed out response to throttle input and reduced backfiring on the overrun.

  7. Martin Pascoe (verified owner)

    Very easy to fit ,much smoother throttle response

  8. Michael W. (verified owner)

    Easy to fit and is smoother, but engine warning light does constantly come on. Hoping this may clear as ecu adapts to its figment.

    • Matthew Milburn

      This should not cause the light to come on, did you turn on the ignition with the sensor disconnected ?

    Not installed but sound packaging

    Booster plug was very easy to fit & as per all the past reviews I researched, it removes the throttle delays at slow speeds, making it a much smoother ride at low revs

    Great company to deal with, great prices too, who could ask for more.

    Easy plug and play and really made a difference with the x pipe fitted at the same time thanks guys

  15. John H. (verified owner)

    Not perfect, but you would have to fit a power commander and do plenty of dyno runs to properly sort the fuelling out, this little plug and play device improves the throttle response by 70-80% over standard. Well worth the cost for the improvement it provides. Plus easily removed if required.

    Quick delivery and well packaged, not fitted yet so cannot say if it improves the bike or not.

    Good service, prompt delivery

    Amazed at how quickly this was delivered. Thought I would be waiting 5 or 6 weeks to ship to New Zealand, only took a week.

  20. Nick (verified owner)

    Hi guys thanks for great service. Ordered the parts from here in New Zealand arrived really quickly. Easy to install. Just need to ride it now.
    Cheers Nick

    Does what it says on the tin, easy fit.

  22. Michael Liston (verified owner)

    Great little gadget that eliminates the lean running when making changes to the air filter and exhaust. Easy to install and actually works. Have now fitted to 3 bikes – Triumph Street Cup, Bmw R NineT and now Triumph Thruxton R

  23. Zoltan K. (verified owner)

    Fast shipping, accurate installation instructions, it works great! First impression: Lower rpm response is a little better. Thanks Tec Bike Parts!

  24. john kelly (verified owner)

    Again does what it says, not popping and banging now !

  25. Dean (verified owner)

    Sorted the miss fireing at low revs 😋

  26. Jim Overend (verified owner)

    Good service. The booster plug improved low speed running and performance.

  27. Anonymous (verified owner)

    The wires to the plug could do with being a couple of inches longer then the unit could have been hidden behind the side panel.

  28. Shaun Williams (verified owner)

    So simple to install, taking only four or five minutes (with reading instructions. This item makes a noticeable improvement on low speed performance to my Street Twin! Only a week in use, and the average MPG still remains the same
