  • SB350D4 - 4 Cyl Direct Port Dry Car Nitrous Kit



The Street-Blaster 350D4 is a frequent choice for high-end petrol engines and benefits from numerous unique features as standard equipment, which offer substantial advantages over all other brands of nitrous systems.

The Street-Blaster 350D4 is a dry, nitrous only direct port system that has been designed specifically for 4 cylinder petrol applications. 
Being a dry nitrous system, it is the customer’s responsibility to ensure that adequate fuel is added to avoid a lean mixture. There are a number of options to increase the fuel flow, but the most common method is to have a 2nd switchable fuel map (to suit the nitrous being added at any time) programmed into the ECU.  

The Street-Blaster 350D4 has the potential to increase the power of your engine by up to 350 horsepower. However, each engine's power output capabilities and total power achievable can vary depending on many factors.
