If the vehicle is fitted with a sophisticated air flow sensor, the TURBO-FLO must be placed after the sensor.
Check Air Filter housing for holes. If present, block using Duct Tape or something similar.
VACUUM TEST Once the TURBO-FLO has been fitted, start the motor and place your hand (cupped) over the air intake entrance. Give a couple of sharp revs in order to feel for vacuum. If not felt, it means there is an air leak and prevents the TURBO-FLO from working.
