Ma muli o ka hana kiʻekiʻe a me ke kumu kūʻai haʻahaʻa o nā ʻāpana metallurgy pauka, ʻoi aku ka nui o nā ʻāpana sintered i hoʻohana nui ʻia a hoʻohana ʻia i ka ʻoihana kaʻa.Ma waena o ka ʻenekini,

ʻO ka ʻōnaehana chassis kaʻa: nā ʻāpana haʻalulu, nā alakaʻi, nā pistons a me ka noho valve haʻahaʻa.Pūnaehana haʻihaʻi ； ʻO ka mea ʻike ABS, nā pale pale a pēlā aku.

Nā ʻāpana ʻāpana: nā mea nui i ka wahie, ka ʻaila a me nā pamu hoʻouna

ʻEnekini: nā alakaʻi valve, kau ʻana o ka ʻenekini, nā lāʻau hoʻohui, nā noho halihali, nā mea nui o ka manawa valve variable (VVT) a me nā kākoʻo paipu hoʻopau;

ʻO ka pahu pahu mīkini: ʻo ka synchronizer hub a me ka mea lawe pahu honua etc.

ʻO nā ʻāpana maʻamau he wela kiʻekiʻe a me nā ʻāpana mīkini pale pale a me nā ʻāpana hoʻouna.
