Hyundai i30N G4KH forged piston kit JE Pistons

Forged high-performance pistons from JE Piston for all G4KF engines, e. g. in the Hyundai i30N and Veloster.

Features:

• Extremely lightweight thanks to special alloy
• Reinforced for maximum power
• Also for stock bore 86 mm
• 22 mm piston pin
• Complete set incl. piston pins, rings and clips
• Installation and bore specs included

The stated compression ratio is in combination with a cylinder head gasket in stock thickness.

From a boost pressure of 2 bar, reinforced TURBO piston pins must be used (see further below).

normal:
Standard forged pistons from JE Pistons. Fully round piston skirt.

Q - Asymmetric:
The asymmetric piston design from JE Pistons. It has a wide piston skirt on the major thrust side and a narrow, friction-reducing skirt on the minor thrust side. Due to this design, for pistons marked with a Q version, our special oil squirters for piston crown cooling must be installed. You can find these below under accesories!

FSR pistons:
The asymmetric FSR (Forged Side Relief) piston line from JE Pistons features a modern forged design with a wider piston skirt on the major thrust side and a smaller, friction-reducing skirt on the minor thrust side. In combination with precise CNC machining, this creates a high-strength, lightweight piston that is extremely durable.

Ultra Series:
The pistons of the Ultra Series combine all of JE’s premium features and the brand-new technology of the forging industry!
JE’s revolutionary Perfect Skirt coating is one of the many technologically advanced aspects of the Ultra Series. It protects the piston skirts, reduces friction and prevents cold-start piston slap and false knock.
All Ultra Series pistons come standard with a ceramic crown coating to guarantee longer life and better exhaust-cleaning characteristics.
Thicker piston pins made from premium material are another feature of the Ultra Series.
In combination with the unique Grain Flow Optimized forging technology, the Ultra Series is ready for massive power.
