Iipistons kunye neentonga zokudibanisa nazo zenziwe ngokutsha. Umahluko obonakalayo yintloko ye-cylinder entsha. Yi-16-valve ye-aluminium ye-DOHC yentloko yesilinda ene-exhaust manifold edibeneyo.

Ikhonkco lexesha lihlala lingachukunyiswanga, kodwa i-chain tensioner yatshintshwa kwafakwa entsha. Inkqubo yamafutha ibandakanya indibaniselwano yenaliti yamafutha ngokuthe ngqo ngaphakathi kumagumbi okutsha kunye nenaliti yesiqhelo ye-multipoint phambi kweevalvu zokuthatha. I-1.8TSI EA888/3 ixhotyiswe nge-IHI IS12 turbocharger. Uxinzelelo oluphezulu lokunyusa iyunithi entsha yi-1.3 bar (18.8 psi).
