UMA spark plug? AB8R3I o AB9R3I?
Ang reaction video na eto ay base po sa aking experienced sa dalawa. Same lang po sila pagdating sa topspeed. Ang kaibahan lang is mas responsive si AB9R31 compare kay AB8R3I.
More power more gas.
Great power comes great responsibility sa gas. Haha
AB8R31: FOR DAILY USE ENGINE//STANDARD BIKE
AB9R31: FOR HIGH PERFORMANCE ENGINE WITH HIGH TEMPERATURE ENGINE
