Hyundai L4KA 2.4 Theta Engine

About this engine

Hyundai's Theta 2.4 — an all-aluminium four with CVVT, balance shafts and a timing chain, and the engine behind the NF Sonata and the 2.4 Tucson and Sportage. 161 hp and 165 lb-ft from a package that weighs under 300 lb, and mechanically straightforward to work on. Our units carry the yard's L4KA tags, visible in the photographs, and are supplied complete with the intake manifold, coil packs and accessory drive. Sold as a used import, exactly as it came out of the donor vehicle and as photographed. The engine code above is the one marked on this unit; we confirm it against the stamped engine number before dispatch. Compression and leak-down testing is available on request before you commit, and every unit carries a 3-month warranty against internal mechanical failure.
