Hyundai G4FJ Engine Parts

The Hyundai G4FJ is the 1.6 litre Gamma inline-4 with a DOHC 16 valve head. It is turbocharged with petrol direct injection. From 2011 it went into the i30 GD turbo and the Veloster FS 1.6 T-GDI. Kia used it in the Cerato Koup YD turbo and it later reached the i30 PD N Line. The G4FJ runs a timing chain, not a belt.We hold 12 parts for the G4FJ.

Pistons and forged conrods

Two piston sets are listed, a Yenmak piston and ring set and a TIK piston set. NVP forged conrod assemblies sit alongside them for builds running more boost than factory.

G4FJ main, conrod and thrust bearings

Genuine Hyundai main and conrod bearing sets are here next to TDC and NDC sets. Those cross-list to the G4FD, the same 1.6 litre with direct injection but no turbo, and the 1.4 litre G4FA. Gamma mains are grade selected from marks on the block and the crank counterweight, so read those marks before ordering rather than assuming standard.

G4FJ timing chain set and water pump

The NVP timing chain set and a genuine Hyundai water pump are the two service items listed.

Also listed for the G4FJ

One NVP full gasket set and a TDC thrust bearing set round out the listing. The thrust set cross-lists across the Gamma family and the gasket set is G4FJ specific.
