  • WON Easy Fit Nitrous Kit 2


The EFNK2 is a virtually self contained nitrous system, as it not only includes all the main parts of a conventional nitrous system (bottle, pipe work, electrics, etc) but also includes a self contained, self pressurised liquid gas fuel cell.

The benefits of the self contained, self pressurised liquid gas fuel cell, in addition to the other unique design features means the EFNK can be fitted and fully functional within MINUTES, so the WON experience can be enjoyed almost immediately, rather than have to wait up to 3 days for it to be fitted.

There’s no need for complex wiring or to add switches to your dash, as the system is quickly and easily arranged to be triggered by the momentary main beam headlamp switch. 

This unique system is suitable for single shots between 25 and 50 HP on small car engines or multiple shots of as low as 5 HP on small motorcycle and scooter engines.

Each system is supplied preset to the power level of your choice to deliver the optimum mixture ratio, so there’s no reason for any concerns about the mixture running lean.
With the mixture being preset, there is no ‘need’ for dyno tuning and the high octane rating of the additional fuel means there is no need to alter the ignition timing on most application. 

Ideal applications for the EFNK2 are;

1) If you have a dyno day arranged and you want to beat the competition, the EFNK2 is ideal.

2) If you have a RWYB or a track day and you’re a little down on power compared to your friend’s car, the EFNK2 will give you the burst of power to put him in his place. 

3) Everyday use on scooters and small motorcycles 

Now the saving on the fitting and dyno time would be enough of an advantage for most people but we’re going to provide our customers with MUCH MORE. 

The EFNK2 will be sold with the following Guaranteed Buy Back arrangement;
