HKS Radiator Cap
2022–2024 Subaru BRZ
15009-AK005
Overview:
The HKS 1.1 Bar N-Type Radiator Cap is a high-performance upgrade designed specifically for the Subaru BRZ model years 2022 through 2024. This radiator cap replaces the factory unit to allow your cooling system to operate at a higher pressure, improving the efficiency and performance of your vehicle's engine cooling.
Ideal for enthusiasts seeking enhanced reliability and better thermal management during spirited driving or track use, the HKS radiator cap helps maintain optimal engine temperatures by increasing the boiling point of the coolant. This ensures your Subaru BRZ performs more consistently under demanding conditions.
Key Features:
The HKS Radiator Cap offers several technical advantages over the factory cap, crafted with quality and performance in mind:
- 1.1 Bar Pressure Rating: Holds higher pressure than the standard radiator cap, raising the coolant boiling point for improved heat tolerance.
- Polished Finish: Durable polished metal construction enhances corrosion resistance and adds a clean, high-quality appearance under the hood.
- Red HKS Sticker: Distinctive branding sticker for easy identification and a touch of style.
- Precision Engineering: Manufactured to strict quality standards ensuring reliable sealing and pressure control.
- Direct Fitment: Designed to fit the Subaru BRZ 2022–2024 without modification, maintaining OEM compatibility.
Construction & Design:
The HKS radiator cap features a robust metal construction with a polished finish that resists corrosion and wear from heat and coolant exposure. Its N-Type design ensures a secure seal and consistent pressure retention, critical for maintaining the integrity of the cooling system under increased thermal loads. The cap’s pressure valve is calibrated precisely to 1.1 bar, allowing your cooling system to operate at a higher pressure than the factory cap, which typically holds around 0.9 bar.
This increase in pressure raises the boiling point of the coolant, reducing the risk of overheating and coolant loss during aggressive driving or track conditions. The cap’s design also ensures easy installation and removal, fitting directly onto the radiator neck without the need for adapters or modifications.
Installation & Fitment:
The HKS Radiator Cap is a direct replacement for the factory radiator cap on Subaru BRZ models from 2022 to 2024. Installation is straightforward and requires no special tools or modifications. Simply remove the existing radiator cap and replace it with the HKS unit.
- No cutting, drilling, or special tuning is required.
- Maintains factory mounting points and sealing surfaces for a perfect fit.
