Overview:
The CSF Aluminum Filler Neck with High Pressure Radiator Cap is a premium upgrade designed specifically for the Subaru BRZ (2013–2024), Toyota 86 (2017–2020), and Toyota GR86 (2022–2023). This component replaces the factory plastic auxiliary filler neck with a durable, all-aluminum construction that enhances reliability and longevity. Ideal for enthusiasts seeking improved cooling system performance and durability, this filler neck is engineered to withstand higher pressures and temperatures commonly encountered in spirited driving and track use.
Featuring a 1.4 bar high-pressure radiator cap, this assembly helps maintain optimal cooling system pressure, improving coolant boiling point and overall thermal efficiency. The included cap is a "mini style" design embossed with the CSF logo, compatible with many aftermarket high-performance radiator caps for easy customization.
Key Features:
Engineered for performance and durability, the CSF Aluminum Filler Neck offers the following key features:
Construction & Design:
The CSF filler neck is crafted from high-grade aluminum, chosen for its excellent heat dissipation and resistance to cracking or warping under thermal stress. The entire assembly is precision TIG-welded, providing a seamless and durable bond that outperforms factory plastic components prone to failure. The mirror polished finish not only adds a sleek, high-quality appearance under the hood but also offers additional protection against corrosion and environmental wear.
The integrated 1/8 NPT sensor port allows for easy integration of aftermarket sensors, enabling enthusiasts to monitor coolant temperature or pressure with precision. This thoughtful design feature supports advanced cooling system diagnostics and tuning.
Installation & Fitment:
The CSF Aluminum Filler Neck is designed as a direct drop-in replacement for the factory plastic filler neck on Subaru BRZ (2013–2024), Toyota 86 (2017–2020), and Toyota GR86 (2022–2023) models. Installation requires no modifications, making it a straightforward upgrade that can be completed in under five minutes by anyone with basic mechanical skills.
For best results, refer to the manufacturer’s repair manual for standard installation procedures. If you are not confident in performing the installation yourself, CSF recommends having the product installed by a qualified automotive technician to ensure proper fitment and function.
What’s Included
Ideal For:
This upgraded filler neck is perfect for Subaru BRZ, Toyota 86, and Toyota GR86 owners who demand enhanced cooling system durability and performance. It is especially suited for enthusiasts who participate in track days, autocross, or spirited street driving where higher cooling system pressures and temperatures are common. Additionally, those looking to replace the factory plastic filler neck with a more robust and visually appealing component will find this CSF product an excellent choice.

ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
