bug help

[pennylane]

I got a New Beetle around 6 months ago, and my boyfriend keeps telling me what (additional) stuff I should get for my Bug.. he went online and found a vw car cover and vw floor mats.. are the ones he found any good, though? He also got me a vw cold air intake, because according to him, mine's "shot".. I haven't noticed anything different, though. What does a busted cold air intake mean? Thanks for the help!
