A new high-compression piston kit is now available for the G16E-GTS engine for your Toyota GR Corolla!

The new piston kit utilizes HKS’s new & unique “Triple Tumble” crown structure. This crown structure allows for a third tumble flow on the intake side of the piston, which helps prevent engine knock.

For best performance, install the piston kit and connecting rods as a set. Installing them separately may cause imbalance and vibrations.

Billet Piston Kit Bore (Φ87.5 / Weight 352g):

To enhance knock resistance and achieve higher compression ration, HKS has adopted HKS's unique "Tripe Trumble" crown structure.

The piston crown's design creates a third tumble flow on the intake side as the piston moves upward. This quickly spreads the flame near the edge of the intake side, which helps prevent engine knock.

High-temperature-resistant A2618 material and precision machining combine to deliver significant weight.

"Bridge Concept Design" (BCD) structure enhances structural rigidity and contributes to weight reduction.

Three oil jets deliver cooling oil precisely for effective cooling.

Nickel plating above the top ring groove improves knock resistance and wear resistance.

A two-layer coating enhances anti-seizure properties and reduces friction.

Original shortening piston pin design reduces the weight of the piston pin boss section.

Titanium coating on the top ring enhances durability.

Precisely machined edges prevent heat spots.

Billet I-beam connection rod:

Features machined nickel-chrome steel I-beam connecting rods. 25% stronger than the stock components.

Compatible with Φ24 piston pins.

Surface is finished with a WPC treatment to increase fatigue strength.
