no more stutter at start off the line ,improved response in sport mode ,7 mpg gain ,engine runs 40 degrees cooler ,believe inlet hose to be best of product line ,increase of 26 hp at wheels ,ram air box feeds into it ,12 second quarter mile. holy shit batman .this hose works better than ascribed to.

put one on a buddies a-3 ,increased horsepower by 22 increased torque by 28 ft lbs ,now he gets better mileage and increased power, the quattro now gets rubber in 3 gears ,incredible power from a silicone tube and a k&n air filter,and you can hear the turbo now and the pop off and crackle when you resume normal driving after pulling onto an entry ramp to the pa turn pike.the engine sound even out side the car makes people look ,inside the car you can hear and feel the difference ,much happier with a boosted audi 2 litre turbo charged engine in his audi ,can't wait until mine comes ,I have a 15 inch titanium tube and a huge K&N performance filter to put on the end.i will also get a larger turbo inlet pipe with a flange to ,mount the silicone tube onto.could have paid 699 bucks and been dissapointed ,this homade system is larger and increases flow into the turbo by 179%,can't wit until it comes and I can install. it,best product cold air intake by at least 79% in every category.looks like stock system when camoflaged with some heat wrap and some t rex clamps.his audi a-3 quattro now goes 12.4 second in a quarter mile ,that's a two second difference and it makes a huge induction sound at about 5700 rpm.used in conjunction with 100 octane non leaded gas you can honestly get 300 horsepower from a two litre turbo charged engine.the local a series club calls this a best product out of many that cost 4 hundred bucks and way up.

This plus a drop in K&N certainly made a sound difference. Nice inexpensive alternative to a CAI.
