Description
Meziere 100 Series Electric Water Pump Insert – Big Block Mopar (Polished)
Eliminate mechanical engine drag and maximize cooling performance with Meziere’s high-efficiency electric water pump insert for Big Block Chrysler engines.
Product Overview
The Meziere WP105U 100 Series electric water pump is an insert-style performance upgrade engineered specifically for Big Block Mopar engines (350, 383, 400, 413, 426 Hemi, and 440 V8s). By fitting directly into the stock water pump housing, this pump eliminates parasitic horsepower loss caused by traditional mechanical impellers—freeing up valuable wheel horsepower at higher RPM. CNC-machined from lightweight billet aluminum with a show-quality polished finish, the WP105U features a 12V electric motor delivering a consistent free-flow rate of 35 to 40 GPM regardless of engine speed.
