IMPORTANT – READ BEFORE BUYING – This product is not USA 50 state compatible and cannot be used in the state of California.  The product is strictly for off-road/race/demonstration use only.  It is not road legal for emissions in the EU or the UK.  It is the customers responsibility to use this item responsibly to comply with local laws.  These parts are not BS-marked, E-marked or TUV-approved.

Do you find your 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 the Royal Enfield Interceptor 650 and Continental GT 650 ONLY

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.

Will NOT work with Euro 5 models as they have anti-tamper built into the ECU, please do NOT try to fit to Euro 5.

Interceptor 650 Booster Plug

I bought the booster plug for my Interceptor 650 as a fail safe for fuelling given the TEC 2-1 Stinger and K&N air filter that I have on my bike. The throttle response is so much better now and really pulls throughout the rev range.

Real boost

I fitted the S&S air filter and the lightweight end cans and although the bike went well, there was a bit of a rawness to the drive and a rasp to the exhaust note. Booster plug smooths every thing out with better clutch control and smooth gear changes. Very impressed at the improvements.

RE Booster Plug

Really easy to install, no further action needed. My RE650 is equipped with a DNA High Flow Air Filter and TEC Cannon Silencers. With the booster plug installed, the engine runs noticeably smoother. Don't expect more horsepower, but one can feel a difference. Should have installed it a year ago.
