Product Description

The HKS 71008‑AH011 Super SQV4 Blow‑Off Valve is a performance‑enhancing turbo component engineered for the 2017–2019 Honda Civic 1.5T (FK7/FC1/FC3). Featuring HKS’s advanced sequential dual‑valve architecture, this SSQV4 design delivers reliable and smooth boost pressure relief across a wide range of driving scenarios — from everyday driving to spirited acceleration. Its pull‑type relief system ensures dependable operation regardless of boost level, enhancing throttle response and helping to protect your turbocharger from compressor surge.

Constructed with a high‑quality aluminum die‑cast body and metal internals, the Super SQV4 valve offers durability and a distinct triple‑fin look that adds visual appeal in the engine bay. Note that this version does **not** include a recirculation (suction return) tube — that accessory is available separately. Designed for direct fitment on compatible models, this BOV is ideal for enthusiasts looking to upgrade both performance and sound. Always verify fitment for your specific model year and trim before installation.
