Air fuel ratio Regulator (AFR) For GRF/GVF: Standard Racing Suction Reloaded Intake Kit corrects the airflow output characteristics by the unique shape of airflow adapter's air guide. For GRF and GVF, airflow correction by the air guide's shape is inadequate; therefore, the AFR is designed exclusively for GRF and GVF and included in this kit. Stable performance can be presented for a stock to a vehicle with the exhaust system, catalyzer, and factory replacement type exhaust manifold.

Features:

Further performance improvement at high RPM leads to smoother accerelation.
Sporty intake sound uplifts driver's sprit.
Airflow output correction device specifically designed for GRF/GVF is included.
