Chase Bays Raised Inline Filler Neck

The Chase Bays Raised Inline Filler Neck is a revolutionary solution for enthusiasts looking to improve the aesthetics and functionality of their engine cooling systems. Designed to address common issues such as air bubbles and low fill points, this innovative product offers a modular approach to radiator fluid management. With its raised fill point and versatile adapter options, it stands out as a top choice for those seeking a seamless and efficient cooling system upgrade.

Innovative Features and Specifications

The Chase Bays Raised Inline Filler Neck boasts several unique features that set it apart from other products on the market. Its raised fill point, located 3.75 inches from the center of the lower fitting to the cap seal, significantly reduces the accumulation of air bubbles in the system. This feature is particularly beneficial for engine swaps and vehicles with lower-mounted radiators. Additionally, the filler neck is modular, offering a range of adapter options to fit various applications. These include 1.38-inch normal hose connections for SR20DET, 1JZ-GTE/2JZ-GTE, Honda, Subaru, and Toyota vehicles, as well as 1.5-inch connections for RB20/25/26, GM LS V8, and KA24DE engines. The product is available in raw aluminum for direct welding to the upper water neck, ensuring a custom fit for any setup.

Practical Uses and Benefits

The Chase Bays Raised Inline Filler Neck is not just a cosmetic upgrade; it offers practical benefits that enhance the overall performance and reliability of your vehicle. The inclusion of two 1/8 NPT ports allows for easy integration of accessories such as water temperature sensors, fan thermoswitches, and freeze ports for LS engines. The product is constructed from high-quality 6061 billet aluminum, bead blasted, and anodized in a semi-gloss black finish, ensuring durability and a sleek appearance. With its Type A radiator cap and standard 4AN ORB overflow port, the filler neck provides a major upgrade over standard components. By choosing the Chase Bays Raised Inline Filler Neck, you can enjoy a more efficient, visually appealing, and customized cooling system for your vehicle.
