If you're looking for more performance in your vehicle, you might want to consider the Fuel Injection Performance Kit from K&N Engineering of Riverside, California, at www.knfilters.com. The theory is that this kit improves a vehicle's performance and its fuel economy because the new intake setup flows a lot more air than the stock system, plus it provides cooler, denser air to the engine. The system is available to fit a wide range of vehicles, and it includes K&N's environmentally friendly Filtercharger air filter, which is washable and reusable and is covered by a million-mile limited warranty. It will cost from $250 to $350, depending on your vehicle type.
The In-Dash DVD/CD player from Audiovox of Hauppauge, NY, (www.audiovox.com) plays both audio and video CDs and DVDs. Its in-dash location makes it easy to fit a mobile entertainment system in a smaller vehicle — and having the entertainment system controller in the dash also makes it easy for mom or dad to change the DVD. About $1,000.
