If you could get a 25% fuel saving by using a different air filter, rest assured, Holden would have supplied one. Thats like those rotor things they put into the air systems too.. if they really had a benefit, the manufacturer would fit it. They spend hundreds of millions of dollars looking for small benefits in economy and power... its in their own interest to come up with the best they can as its a huge selling point.
If you got a 25% fuel saving by fitting a new air filter, then your old filter was not allowing enough air through, and any new filter would have made the same difference.
Chevy badges look good on Chevy V8 Commodores. They don't belong on V6s. The same as Turbo badges don't belong on naturally aspirated cars.. If you cant tell the truth with your badges, then do as I do and just have no badges at all, keep em guessing lol.. the only badge on my car is the Holden Lion on the boot. If it had a Chevy V8, I would replace that for a Chev badge.
To the O.P .. just clean your car regularly and well, and it will already look better than most. Don't buy a bunch of cheap crap to dress it up with.. save ALL of the cash and buy good stuff that you actually want, when you can afford it.
