The G4NA is the Hyundai and Kia 2.0-litre four-cylinder petrol engine from the Nu family, fitted to the i30, Tucson and Elantra. Most listings also cover the related G4NB and G4NC, so read the code off the block rather than assuming from the model.There are 38 parts listed for the G4NA. The G4NA runs a timing chain, not a belt.
Cam timing and valvetrain
Genuine oil control valves for the inlet and the exhaust cam, the exhaust VCT gear and the pivot guide bolt. The inlet and exhaust OCVs are different parts, so tell us which end you are replacing. Rocker arms are supplied one at a time, so count how many you are short before you order.
G4NA bearings and rings
Main bearing sets from NVP and TDC, and TP ring sets in 0.5mm oversize.
More G4NA parts on the shelf
Genuine head gaskets, rocker cover gaskets and the fuel pump gasket, along with the tin sump oil pan, the oil pick up pipe and the harmonic balancer.
