HKS GR Corolla BCD Piston + Conrod Kit G16E H-COMP Triple Tumble STEP3

Product Specifications

New G16E-GTS Piston & Conrod Kit for High Compression:
Original Piston Crown Design to improve knock resistance

Parts Included

• Piston Kit D87.5 (incl. Piston Rings and Pins) (Billet, machined, nickel plated, 2-layer molybdenum coating)
• CONROD SET G16E STEP3

Key Features

•  Piston Diameter: D87.5 / Weight: 352g
• To enhance knock resistance and achieve higher compression ration, we have adopted HKS's unique "Triple Tumble" crown structure. (Triple Tumble 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 connecting rod:

• Features machined nickel-chrome steel I-beam connecting rods. 25% stronger than the stock components.
• Compatible with 24mm piston pins.
• Surface is finished with a WPC treatment to increase fatigue strength.

Compatibility

• Toyota GR Corolla G16E-GTS GZEA14H AWD

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