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 and no wire cutting required. It has a no quibble money back satisfaction 60 return and a lifetime product limited warranty

Booster Plug Triumph Bonneville T100

After watching various YouTube videos about the booster plug and not being totally convinced I finally pulled the trigger and bought one. I have to be honest and say after four ride outs with it fitted to my bonnie the throttle response at low speed is so much better and no need to feather the clutch like before.
The Booster Plug is a thumbs up from me and a keep!

Top company

Superb service and very quick delivery as always, great quality products.

Great kit

Fitted to my Thruxton 900 as it was a bit snatchy at low speeds. It has smoothed the issue massively, I also have one on my RE interceptor 650 which is great too. I highly recommend Tec after using them a lot in the last year. They are always helpful and have quick delivery. Great all round service.

Booster plug, a must have part.

I have replace parts and tune my Scrambler engine with tec parts, but the must is a fuel booster. Smooth running, and a well behaved engine now. Must have part. Chris


Works fine and is easy to install.
