T4 is designed for stock or slightly modified 4-stroke engines. Unleaded and ethanol-freeT4 is a direct pour-in replacement for premium pump fuelwhich has a short storage life and has caused a heightened need for repairs in all engines after periods of non-use. While riders facing extreme conditions are forced to add octane boosters or race fuel to increase the octane of pump fuelT4s 103.5 octane rating provides greater protection against detonation. (Compared with more expensive performance parts that increase power along only a small slice of the power curveT4 offers 2-3% more power and better throttle response across the entire RPM range.)
