The HKS Super SSQV4 blow-off valve kit for 2017–2019 Honda L15C and L15B engines supplies the SSQV4 valve without the recirculation tube. Offered for those specific engine applications, the kit provides the valve assembly itself so installers can use it in open-venting setups or add custom recirculation plumbing separately. It is intended for 2017–2019 L15C/L15B Honda applications as described.
