Product Description
2.5" Top Hat + Powerpipe Non Dump Valve Connection for Astra Zafira GSi SRi Z20LET Turbo
The TX Autosport 2.5" Top Hat + Powerpipe Kit (Non Dump Valve Connection) is a high-performance upgrade designed for Astra and Zafira GSi, SRi, and other models equipped with Z20LET turbo engines. This kit is a direct replacement for the standard tophat and rubber boost hose, offering improved throttle response and sustained power throughout the rev range for an all-around better driving experience.
Featuring a 63mm (2.5") stainless steel tophat and matching powerpipe, this kit significantly increases airflow and eliminates restrictions caused by the tight bends in the factory setup. The solid powerpipe design prevents power loss from hose expansion or collapse, ensuring consistent performance.
Suitable for standard and modified cars, this kit connects seamlessly to factory or upgraded intercoolers and is available in various colours to match your customisation needs. Installation is straightforward and requires only basic tools, making it an ideal choice for both professionals and enthusiasts.
