ok i seen this on trademe and i just had to post it mainly because of its title "Super Fast Bling Bling Racing Majiggy"
"This is called a air charger i brought 2 of them and have no idea how they work so put them up with $1 reserve auction.
Our air-chargers are designed to dramatically increase air-intake in the factory air filter system. More air means more usable power and acceleration throughout the engine's RPM range, with even greater power gains in turbocharged and supercharged engines.
Our air-charger is different from other after-market air-chargers that require entire factory air filters and the whole air path to the engine to be replaced. Our air-charger uses a three-way nipple that connects the existing factory air-intake system to the air-charger.
the extra volume airflow into the engine is adjustable. Turning the adjustment screw on the air-charger adjusts the air intake volume.
The filters on Our air-charger are washable and reusable
*This auction is for the blue 1*"
