Product Overview
Speedway Motors Water Flow Restrictor, 1-5/8"
Improve your engine's cooling efficiency with the Speedway Motors 1-5/8" Water Flow Restrictor. Precision-machined from lightweight billet aluminum and finished with a durable anodized coating, this coolant flow restrictor installs in the lower radiator hose neck to regulate coolant velocity through the cooling system.
By slowing and smoothing coolant flow, the restrictor reduces turbulence and allows the coolant to spend more time in the radiator, increasing heat transfer for improved cooling performance. It's an excellent solution for circle track, drag racing, hot rods, and other high-performance applications where maintaining consistent engine temperatures is critical.
Features:
- Fits 1-5/8" lower radiator necks
- Precision-machined billet aluminum construction
- Durable anodized finish for corrosion resistance
- Reduces coolant turbulence for smoother flow
- Increases radiator heat dissipation by slowing coolant velocity
- Helps maintain more consistent engine operating temperatures
- Ideal for racing and high-performance cooling systems
Whether you're fine-tuning a race car or upgrading your street performance cooling system, the Speedway Motors Water Flow Restrictor is a simple, effective way to maximize radiator efficiency and help keep your engine running cooler.
