  • Lifetime guarantee.

  • Micro bore nylon hose for maximum efficiency.
  • EU specification nitrous bottle with FlowMax valve & SPRV.
  • Laserlite QD nitrous bottle quick release mounting system.  


If you want a simple to fit, well-priced system that delivers maximum reliability and power; the Street-Blaster 150i has been developed by WON with you in mind. Having just one injector it is our lowest priced system and also the easiest and quickest to fit. This system is for street use but can be upgraded to race use by replacing our nylon pipe with our braided hose. Whether it’s purely for an adrenaline fuelled thrill or the more serious use of gaining a competitive edge, the Street-Blaster 150i can deliver a boost of up to 150bhp, whenever you need a burst of acceleration. Utilising the same high-quality components as our ultimate race, Pro-Series systems the Street-Blaster 150i offers peace of mind and impressive results at a very competitive price. 


Although it is indisputable that our nylon supply pipe is the best option for customers who don't need to flow more than 150bhp and who live in mild climates, if you’d prefer to use braided hose or need it to suit a race regulation or a hot climate, it can be selected from the drop down menu.
