Relocating the air box from the engine compartment to the wheel well, so cooler air is being drawn in. 1  The larger intake tube increases volume of air being drawn into the combustion chamber, which allows for better burn.

SYSTEM.SAV, in-place upgrades / repair installs and disappearing registry modifications.. by Carl on Dec.11, 2010, under Computer Stuff. Many people know that there is a file called SYSTEM.SAV under \windows\system32\config, along with all the other registry hive files.
Any changes we made were lost when we rebooted! Well this is what SYSTEM.SAV is all about. It seems that during the in-place upgrade / repair install, Setup is moving the existing SYSTEM registry to SYSTEM.SAV, and it is dumping that into a new SYSTEM each time it is started, or something to that effect.
