my mech told me about this. upgrade standard kelisa piston to this piston, the head is curved inward like a mangkuk shape so creating more space for extra air and fuel than our curved outward standard piston so every stroke got more power
this way is more economical for small budget engine mod coz no need to rebore, the diameter and size exactly the same. for standard car this mod will be good enough for most daily drivers.
anyone tried this?
