Overview

It helps to increase boost pressure response between shifts, reduce compressor surge, and minimize premature boost leakage. This is the 4th generation of Blitz's Super Sound blow-off valve, featuring refinements for improved manufacturing and operation.
Show original supplier description
It directly addresses issues like compressor surge and premature boost leakage, while also increasing boost pressure response during gear changes. This 4th generation model builds on over 25 years of development, incorporating refinements for better manufacturing, improved operation, and enhanced anti-corrosion properties for a stylish engine bay dress-up. The kit includes the head unit, a vehicle-specific pipe, and all necessary hoses, clamps, and fittings for installation. A refined venturi design significantly enhances airflow speed for a sharp release. The internal spring is adjustable, and the spring rate can be modified for custom applications. The head unit can also serve as a direct replacement upgrade for previous versions of piping and adapters. This specific kit is designed for the Toyota Celica GT-Four ST205 with the 3S-GTE engine, fitting models from 1994/02 to 1999/09. It is also compatible with the Caldina ST215W (97/09-02/09 GTE only) and ST246W (02/09-05/01 GTE only, and 05/01- GTE only). However, for ST246W models from 05/01 onwards, a Strut Tower Bar cannot be installed concurrently. It is noted that this product cannot be installed with the Blitz Core-type Air Cleaner Series. Buyers are advised to confirm fitment details with the seller if unsure, as car fitment can vary based on year, ABS equipment, and trim.
