SpeedFactory Street Series Fill Pot for Honda B-Series Engines
The SpeedFactory Street Series Fill Pot is the ultimate solution for maintaining a clean and efficient cooling system on your Honda B-Series engine. Designed for enthusiasts running B16A, B18C1, B18C5, and GSR engines, this billet aluminum fill pot allows you to fill and bleed air from the highest point of your cooling system — ensuring optimal performance and reliability, whether you’re using a custom radiator or a SpeedFactory Racing Tucked Radiator.
Unlike the Race Series Fill Pot, the SpeedFactory Street Series Fill Pot is fully compatible with factory components, including the distributor and VTEC solenoid, making it perfect for both street and track applications. It conveniently raises the system’s fill point, allowing for easy bleeding and refilling, while also increasing coolant capacity by approximately 0.75 quarts for improved heat dissipation and system stability. Each unit comes with a SpeedFactory Titanium Oil Pressure Switch Delete in a raw finish for a clean, functional installation.
Every SpeedFactory Street Series Fill Pot includes a SpeedFactory Racing High Performance Type A 18.8 PSI radiator cap. This upgraded cap increases cooling system pressure, raising the boiling point to enhance overall efficiency and protect your engine from detonation or overheating under extreme conditions. Precision CNC-machined from high-quality aluminum, each fill pot is engineered to provide a perfect fit, superior durability, and a sleek black anodized finish for corrosion resistance.

Installation Tip:
For proper installation, the VTEC Oil Pressure Switch must be removed and replaced with the included titanium plug. Be sure to reuse your factory O-ring. If your engine is equipped with a USDM ECU and lacks a VTEC Oil Pressure Switch signal, you can easily bypass this by tapping the pressure switch wire (ECU Pin D6) into the VTEC solenoid wire (ECU Pin A4). This ensures proper VTEC functionality without cutting or disabling the solenoid circuit.
The SpeedFactory Street Series Fill Pot is the ideal upgrade for B-Series owners looking for professional-grade cooling system maintenance, improved engine reliability, and a clean, functional engine bay.
