HKS SUPER SQV4 RETURN KIT PLUS VMG/VM4

■FEATURE

Installing this product creates unique sharp & high frequency SQV sound. The SQV IV unit is designed to be located beside the engine so the appurtenance of the engine bay is improved.

The suction-return parts are included (those are necessary to pass the Japanese Automobile Inspection.).
Any engine failure such as engine stall was not occurred during the in-house testing.
