The Street-Blaster 150iD4 benefits from numerous unique features as standard equipment, which offer substantial advantages over all other brands of dry nitrous systems.


Before choosing the Street-Blaster 150iD4 or any other dry system, please consider the following;


  • Although the system is called 'dry' it is still necessary to add extra fuel to your engine, when the nitrous system is activated.  Injecting nitrous oxide only produces extra power by allowing more fuel to be burnt.
  • To get significant and safe results you will need to add extra fuel via a fully mapable ECU that can switch between 2 maps and you may also need to fit bigger fuel injectors. 


The Street-Blaster 150iD4 has the potential to increase the power of your engine by up to 150 horsepower (possibly more), depending on the type of vehicle and/or choice of supply hose (WON nylon or braided SS hose). 

As standard the system is supplied with WON's unique nylon 5mm OD ultra high pressure nitrous supply pipe, which keeps undesirable gaseous nitrous to a minimum. There are many advantages to selecting this option, one of which is that it saves you the expense of adding a purge kit to the system, but our nylon pipe does limit the power capability of the system to approx. 100 HP. 

We also offer stainless steel braided hose, as an alternative option (which can be selected from the drop-down menu) but it is only advisable, if 1 or more of the following options apply to you ;

1) you live in a hot country where temperatures regularly exceed 30 degrees

2) you are involved in a motor sport that has regulation that stupidly dictate the use of this type of hose

3) you want more than 100 HP from a WON system. 

However, should you choose the braided hose option, we strongly recommend adding a purge kit to your order, to ensure you achieve optimum performance from your WON system purchase. 


If you want a simple to fit, value for money system that delivers maximum reliability and power; the Street-Blaster 150iD4 has been developed by WON with you in mind. This system is for street or race use, whether it’s purely for an adrenaline fuelled thrill or the more serious use of gaining a competitive edge. The Street-Blaster 150iD4 can deliver a boost of up to 150bhp (depending on the factors already mentioned), whenever you need a burst of acceleration. Utilising the same high-quality components as our ultimate race, Pro-Series systems the Street-Blaster 150iD4 offers peace of mind and impressive results at a very competitive price.
