Racing Suction

Code No. 70020-AF106

 

 

 

■Feature

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.

 

 

■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 & 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.
