Product Description

The Go Fast Bits T9014 Respons TMS Blow-Off Valve Kit is a direct-fit upgrade for select Hyundai and Kia Smartstream 2.5 T-GDI models, including Elantra N Line, Kona N Line, Sonata N Line, and Stinger. Designed to replace factory dual-port diverter valves, the Respons TMS uses a patented venting bias adjustment ring to let you choose exactly how much air vents versus recirculates - zero to full atmosphere or anywhere in between.

Because of its balanced piston design, the Respons provides unmatched boost holding capability without needing spring swaps for different boost levels. With up to 30 % faster turbo recovery on gearshifts and improved throttle feel, the valve enhances both performance and the iconic blow-off sound. Installation is purely bolt-on with no tuning required for compatible vehicles, and the system won't cause stalling or ECU faults - even with MAF-equipped engines.

Manufactured in Australia to ISO 9001 standards, this premium valve includes a lifetime warranty and is built for racing and street builds alike. Please note, T9014 is race-only and not emissions certified - designated for off-road use.
