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


If you want a simple to fit, well priced system that delivers maximum reliability and power; the Street-Blaster 150i4 has been developed by WON with you in mind. 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 150i4 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 150i4 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.  

Whether you need or just want to experience the WON buzz, a Street-Blaster 150i4 will deliver - order online NOW!
