Fits all air cooled EFI T100-Bonnevilles-Thruxton- Scrambler-America-Speedmaster and SE models. just email us your yr/model 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 and no wire cutting required. It has a no quibble money back satisfaction 60 return and a lifetime product limited warranty

if anybody is contemplating installing the fuel booster, do it. It has smoothed out the jerking motion at low speeds, it now accelerates smoothly from Idel, starts perfectly and idles from cold, just buy it you won't be disappointed and is very easy to install.

Very good product, the Booster plug works as advertised and Tec Bike parts customer service and delivery timing is also just first rate. I highly recommend both Tec Bike parts and their products.

Fuel booster plug

I bought the fuel booster plug to fit to my air cooled Bonneville with 130,000 klm on the speedo. I fitted an efi fuel controller early on and thought it did a good job until….it didn’t. So I gave the booster plug a try. Brilliant. Easy to fit and a much better result than previous very happy and delivery to Australia was only a few days great service, thanks.

Booster Plug

Great service and delivery. Easy to fit (once original plug located !). This was under the fuse box on 2015 T100 NOT where it appears on many fitting videos that I have seen. Immediately noticed the difference in low gears.
