Product Description
TX Autosport Top Hat & PowerPipe Dump Valve Connection for Astra Zafira GSi SRi Z20LET Coupe Turbo
The TX Autosport Top Hat & PowerPipe Kit with Dump Valve Connection is an essential upgrade for Astra and Zafira GSi, SRi, Coupe Turbo, and other models equipped with the Z20LET turbo engine. This kit replaces the restrictive factory top hat and rubber boost hose with high-flow components designed to improve throttle response, airflow, and sustained power throughout the rev range.
The 76mm (3") stainless steel top hat offers significantly improved and upgraded air intake within Z20LET engines by reducing tight bends, while the 63mm (2.5") stainless steel powerpipe increases airflow and eliminates power losses caused by the standard rubber hose collapsing or expanding under pressure. Designed to connect seamlessly with standard or upgraded intercoolers, this kit is compatible with both standard and modified cars.
Installation of the Top Hat & PowerPipe Z20LET Upgrade is straightforward, with full photographed fitting instructions included, making it an excellent choice for DIY enthusiasts and professionals alike.
