By installing SuperSQVIV, you can clearly hear the high frequency and sharp operating sound unique to SuperSQVIV, which greatly emphasizes its presence.
By replacing the fin with the included SF100, you can enjoy a different sound quality (low frequency) than with regular fins. When using SF100, the volume will be lower than normal fins.
In addition, it has a strong presence in the engine room, and has an excellent dress-up effect. A return kit is also included. No symptoms such as engine stalling due to installation of this product were observed during our testing.

A dedicated kit fully compatible with the Honda S660 (Model JW5 / Engine S07A Turbo, Year April 2015–). Since it matches the vehicle type, engine, and year, installation is straightforward. The kit is designed with consideration for combining with genuine parts and maintaining proper clearances.
●Standard Suction Return Kit Included
Equipped with a hose nipple and kit that allow switching between atmospheric venting and suction return for sound level and inspection compliance. You can enjoy powerful sound during regular driving while easily returning to a quieter mode when needed.
●Distinctive High-Frequency Sound / Sound Adjustment Option Available
With the standard fin installed, you can experience a “sharp high-frequency operation sound.” By replacing it with the SF100 fin, the sound shifts to a lower, more subdued tone, allowing you to adjust the sound according to your preference. You can choose the character of the sound yourself.
●Reliability Through Structure and Materials
