Description

The HKS Piping Kit is a precision-engineered aluminum and silicone pipe set designed to replace the stock plastic charge pipes on the GR Yaris. Engineered to support increased boost and power, it eliminates the common issue of factory hoses blowing off under pressure while improving throttle response and durability. By increasing pipe diameter, optimizing the layout, and using robust materials, this kit ensures reliable and efficient airflow between the turbocharger, intercooler, and throttle body for both stock and upgraded intercoolers.

Product Overview & Purpose

The factory turbocharger piping on the GR Yaris utilizes plastic components and rubber hoses prone to expansion and separation under high boost, especially as power is increased. This kit provides a complete, heavy-duty solution. It replaces key sections with larger-diameter aluminum pipes and high-pressure silicone couplers, creating a secure, leak-free path for pressurized air that can withstand the vibrations of the 3-cylinder engine and the demands of tuned performance.

Product Highlights

🔧 Prevents Hose Blow-Off & Improves Reliability
Replaces the stock rubber hoses and plastic connectors that are prone to popping off under boost with a combination of rigid aluminum pipes and 4-ply molded silicone hoses. The aluminum pipes provide a solid anchor point, while the reinforced silicone hoses offer excellent pressure resistance and vibration absorption, specifically tuned for the G16E-GTS engine’s characteristics.

🌬️ Increased Diameter & Optimized Flow
Increases the charge pipe diameter from the stock φ45mm to φ50mm. Combined with a layout designed to minimize bends, this reduces airflow restriction and pressure loss between the turbo and the engine. The result is improved turbo response and more efficient delivery of the cooled, dense air from the intercooler.

⚙️ Universal Fit for OEM & HKS Intercoolers
The kit is intelligently designed to be compatible with both the stock intercooler and the HKS Laminated Intercooler (13001-AT008), offering a valuable upgrade path. It also features a layout suitable for vehicles equipped with an aftermarket blow-off valve (BOV) or sequential valve (SQV).

🔩 Complete Kit for a Total Upgrade
Includes all necessary components for a comprehensive replacement: 1 inlet pipe, 2 outlet pipes, and 4 high-pressure silicone hoses with heavy-duty constant-tension clamps. This ensures a complete, leak-free system when installed.

Technical Specifications

• Product Name: Piping Kit

• Model Code: 13002-AT002

• Compatibility: Toyota GR Yaris (GXPA16, G16E-GTS, September 2020+). Mandatory for use with the HKS Intercooler on Gen2 (04/2024+) models.

• Pipe Material: Aluminum Pipes, 4-Ply Molded Silicone Hoses.

• Pipe Diameter: φ50mm (vs. stock φ45mm).

• Key Benefit: Prevents hose blow-off, reduces pressure loss, improves durability.

• Kit Includes: 3 Aluminum Pipes, 4 Silicone Hoses, necessary clamps.

Performance Philosophy

• Goal: To provide a robust and efficient airflow path that supports increased performance levels by solving the stock system’s weaknesses. The focus is on reliability under pressure, improved response, and future-proof compatibility with intercooler upgrades.

• Focus: A critical supporting modification, especially for tuned vehicles. It is the essential “plumbing” that ensures the power gains from your intercooler, turbo, and tune are delivered reliably to the engine without interruption or leakage.

Installation & Synergy Notes

• 🔧 Professional Installation Recommended
  Installation requires removing the front bumper and carefully replacing multiple sections of the charge piping. Proper alignment and secure clamping are crucial to prevent leaks. Professional installation is highly recommended.

• ⚠️ Critical Compatibility & Requirement Notes

  • For Gen2 (04/2024+) Models: This Piping Kit is REQUIRED when installing the HKS Laminated Intercooler (13001-AT008) due to revised factory pipe routing.

  • Synergistic Upgrade: This kit is the perfect companion to the HKS Intercooler, creating a complete, high-flow cooling and intake charge system. It also pairs ideally with the HKS Carbon Racing Suction and engine management upgrades.
