The Street-Blaster 300i8/2 is a special direct port system for 8 cylinder (commonly V configuration) fuel injected engines with 2 throttle bodies that are more than 12” apart (as most are).  This twin pair Pulsoid system delivers exceptional results, without the potential risks associated with using the standard direct port system and its single pair of Pulsoids - the Street-Blaster 150i8.

Whilst the standard Street-Blaster 150i8 is suitable for most 8 cylinder engines, the extra pair of Pulsoids in the Street-Blaster 300i8/2 ensures;


  • There is no delay in power delivery.
  • There is no risk of a backfire due to excessively long outlet pipes. 
  • Better results.

This system benefits from numerous unique features as standard equipment, which offer substantial advantages over all other brands.
