Not sure about it guzzling fuel as i've only done 15 miles since its been fitted... logic would suggest that its there not just to let more air in but be more responsive in doing so, may of course then let more air in and therefore burn more fuel but that wouldn't be noticable... quite often its because you tend to become more heavy on the old right foot!!

Basically you're putting the same amount of fuel in but managing to burn more of it with the colder, more dense air... therefore theoretically making it more efficient. All depends if the ecu puts more fuel in to compensate more air, which i think it does... So in short, I have no f*ckin clue
Deffinately noticed a smoother power range and little more quicker to rev...
