Engines like cool air
Cooler air = increased performance
An engine bay is obviously going to be warm because the engine is warm which then heats up the surrounding air
If you have an open (cone) air filter, most of the air it will suck in will be warm air which is being heated by the engine
The will likely decrease performance
By getting an enclosed induction kit, the filter is covered (so unable to suck in warm air) and you also have a cold air feed going to the front of the engine bay (near the radiator) where it will be able to suck in cooler air, which will increase performance
The gains won't be massive, on a VTS/GTI engine were talking 4-6bhp but combined with a decent manifold, decat and exhaust system, you will notice a performance difference
