Do you find your EFI bike prone to stalling at low engine speeds, lack of throttle response and a lumpy feel to your motor?

Have you fitted a free flow exhaust and worried about it running too lean?

Then this plug and play device will resolve these problems without the need to re-map you ECU.

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

2011 865 bonneville se booster plug

Made a huge difference to how smooth the bike is and has reduced engine braking, I have the tec 2 into one exhaust fitted as well. Easy fit and was running bike in under 10 minutes! Would recommend if your after a smoother bonneville with a xtras like a nicer sounding exhaust!

It made a difference

I bought this for my stock Bonneville SE 2014 and what a difference it made. It's noticeably smoother for setting off and changing into 2nd gear and somehow the engine braking feels less strong. The ride is now much more enjoyable.

Fuel Booster Plug

Recently purchased my 2015 Bonneville SE Newchurch, lucky for me it came with the TEC Sprint 2-2 short full s/s exhaust and apart from a bit of hesitation at low speeds it performed well, in fact I was surprised there was no exhaust popping on the overrun. I also recently fitted a full AIS valve eliminator kit the one with the resistor to plug-in. And now to compliment all of the above I've just purchased from TEC their Fuel Booster Plug & their DNA High Performance Filter which arrived in just 2-days from placing my order brilliant, all dead easy to install. Took the Bonny for a test ride and the difference is not only noticeable but really smooth and crisp. In conclusion I can only highly recommend the fitting of the booster plug, and of course all the other mods that have been done and previously done. Next stage will be the suspension front & rear. Thank you to all at TEC for your prompt service and advice.....

Booster plug

Fitted to 2014 T100. Had taken 1 baffle out of exhaust. Fitted booster plug in 10 minutes. Fantastic improvement. Removed low speed hesitation in town traffic conditions, stopped engine braking backfire and generally more responsive acceleration. Fantastic!

Scrambler snatch is tamed…..

My 2013 EFI Scrambler Had the typical snatchyness when going back onto throttle at low speeds round town. Read the boosterplug rebiews & thought I’ld give it a go. Kit looks well made, was easy to fit tho some zip ties were needed it to secure it so it didn’t drop down to wards the chain. & put strain on the connectors. Went for a test ride and what a transformation…no longer feels like i’m riding a bucking bronco when in slow traffic - well worth doing! Service & delivery from TEC parts was A1👍🏻

Booster plug SE 2011

Parts arrived very prompt, good packing etc. Clear instructions, fitted in 10 minutes. The SE has been fitted with Norman Hyde pipes but with DB killers and the re-circulation taken off. General running was ok but it had the tendency to stall at a partial throttle. After fitting the Booster plug the "bottom end" seems smoother and the weakness that appeared to be the cause of the stalling has been vastly improved. I have only done in the region of 90 miles but on the first impressions the Booster plug has achieved the reason to fit it.

865 bonneville booster plug.

Plug, then went for a 150ml ride, snatchyness all but gone at lower speeds. Not perfect but a massive improvement. Not an easy fix on a big twin. Acceleration noticeably improved. This has made the bike more enjoyable to ride. Money well spent. Very good company to deal with. Thank you tecbikes.

T100 soughted

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.

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.

BOOSTER PLUG

Having read several reviews on Booster plugs I decided to take the plunge and fit one to my Bonnie SE. It has made a real difference at the low revs end, virtually eliminating the annoying chug at low speed or when in traffic. Better response during acceleration too, so the combined benefits do justify the money spent. Steve H…. Cornwall

Unbelievable

I'm always slightly sceptical when I look at plug in "performance products" but I'm actually amazed by this little plug in wonder. Smooth throttle pick up, no more jerking in low revs and starts on the button without pulling the throttle fast idle out. 5* from me for sure

Booster plug

Just returned from my first ride on my 2013 Bonneville 865 since fitting the booster plug.What a difference this has made,my bike runs smooth at any rpm and in any gear and acceleration is instant with no jerking if rpm is too low. Great product and well worth the money.

5 Star service

Bought this then found that one was already fitted to my Bonneville. Returned for a full refund, great service from a top company. My excuse is that I’ve only just returned to biking after 30 years.

Great service from Tec as normal. Very pleased with the booster plug for my 2015 Triumph Scrambler. Easy to install and it has greatly improved the bikes thottle control - especially at low speeds around town. Highly recommended.

Fuel booster

I have a 2012 Bonneville 865 but having owned it for nearly 12 months I considered getting rid of her only due to the snatchy clutch and poor handling around town at low speeds. Having read good and bad reviews online for the fuel booster I optimistically parted with £130 and really not 100% convinced it would work and solve the issue. But to my amazement after spending 5 mins fitting the booster plug and driving down the road, around town its like riding a completely different bike!!! Don't know how it works and don't really care, Its the best £130 I've spent on any bike and would 100% recommend it to anyone.

The Booster does work and noticably.

Tried a booster on another bike and did make a marked difference. So tried it as available for the Air Cooled Bonny and it has also noticeably improved tick over, low throttle smoother response and a more linear and smoother acceleration on the throttle and less popping on overun, Like most machines they are programmed to run I feel too lean but the booster has given imho a real improvement for a reasonable and uncomplicated cost.

It’s good!

It does work. The booster plug takes up that slack area at the very bottom of the Rev range. So there’s less snatch on and off throttle. There’s less pop from the exhaust too. I defo recommend it.

Fuel booster plug

After fitting the fuel booster plug onto my 2015 air cooled Scrambler, the difference in low rpm and throttle response together with a slightly richer mixture has made the bike near perfect with the Arrow exhaust. The bike now runs without popping as it should, and pulls hard through the rev range. Money well spent.

Every bike should have one

What a great bit of kit .Easy to install and wow what a difference. Firstly no choke to get it running from a cold start ,hate playing around with that. Smooth delivery of power all the way through the gears and way more responsive .Have taken the baffle out of my Tec 2-1 now and it sounds awesome, thanks everyone at Tec ,great service, quick delivery and fantastic advice

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!
