HKS 93-96 RX7 TT SSQV4 BOV Kit
The HKS SSQV4 BOV Kit delivers precise control over excess boost pressure for 1993-1996 Mazda RX-7 Twin Turbo models (FD3S). This complete assembly includes the SSQV4 valve, RX7-specific adapter flange, gasket, and hardware for direct bolt-on replacement of the stock pipe. It safeguards turbos from compressor surge while producing a sharp, audible release that enhances driving feedback.
Key Features
- Dual Sequential Valves: Small valve operates at idle and low boost for quiet performance, large valve engages at high boost for full discharge without compressor surge
- Pilot Actuator Design: Handles pressures up to 2.0 kgf/cm² (29 psi) reliably, preventing valve flutter under high-boost conditions
- Adjustable Preload: Turn the adjustment screw to fine-tune valve opening for specific boost levels and driving preferences
- Direct Fit Kit: Includes dedicated RX7 intercooler pipe flange and straight piping to replace stock setup seamlessly
- High-Flow Capacity: Oversized discharge port supports increased airflow from upgraded turbos and intercoolers
