DYNOJET KIT YAMAHA XTZ750 1989-1993 STAGE 2

Designed for motorcycles with a stock or mildly modified engine using a well- designed stock or aftermarket pipe with a modified airbox and a stock or K&N replacement air filter. Stage 2 kits are designed for applications where individual air filters cannot be installed and for applications where airbox modifications improve overall engine performance. In most cases power increases of approximately 8% can be achieved.
