Stillen G3's those who own with real results please Chime in

"Since the stock intake system is so efficient we were pretty sure that the Stillen intake was not going to make much difference and we were both right and seriously wrong. When running on the dyno, the Stillen intake produced on the average 3 more whp but less torque at 270 whp and 216 lb/ft with the power gains coming high in the powerband above 6700 rpm. Below 6700 rpm, the Stillen Intake lost a slight bit of power and torque. This isn’t the whole story though. For the sake of curiosity, we removed the front bumper fascia and ran the car with the airflow of the dyno’s cooling fan blowing straight on the filters. We were amazed to see that the Stillen intake belt out an additional 10 whp nearly completely across the board! Not believing our eyes, we ran the car with the bumper cover off for many pulls and the numbers repeated. We then replaced the bumper cover and the power numbers dropped to what they had been.

Stillen’s cold air intake is clearly a superior design with great power potential but the bumper traps hot air in the vicinity of the filters which nullifies most of the gains. We hope Stillen reads this and creates a bumper vent and heatshield kit so that the full potential of this great intake can be realized. Since people do not drive without a front bumper we are only going to show our with bumper cover power results."

You G3 tubes were ice cold? lmao. Then the engine was too.

and more mileage means less power?

if the engine can burn its fuel more effectively than stock and the ECU adapts then I don't see why its impossible.

hell I know plenty of people who chiptuned their car and got more power while drinking less fuel.
