Lesi sikhwama se-oyela senziwe ngengxube ye-aluminium eqinile eyenziwe ngokubunjwa okunamandla, sinokubunjwa okunembile nokuphelele kwendawo. Zonke izimbobo zokufaka zihlelwe ngokunembile ukuze kuhlangane kahle ngesikhathi sokuhlanganisa. Ngokusebenza okuzinzile kwesakhiwo nokushisa okuhle, kusekela izingxenye zangaphakathi zepompo ye-oyela futhi kuqinisekisa ukusebenza okuzinzile kohlelo lokuthambisa injini. Kuhlangabezana namazinga we-OEM, futhi kuyingxenye eshintshayo esezingeni eliphezulu yokulungisa imoto.
