Hey I have a 2006 ford focus and its kind of slow for me... I want something that will pump it up even just a little bit... I was thinking about getting a cold air intake because I know where to get those pretty cheap and I don't have too much money that I can spend on this. Is a cold air intake a good choice? Is there something else that I could get for around the same price that would work better?

. Use 5W-20 full-synthetic engine oil; e.g. Mobil 1.

. Use the proper full-synthetic transmission fluid. If it's an automatic, use Mobil 1 Synthetic Transmission Fluid. It's available at WalMart. Be sure to drop and clean the pan, and replace the transmission filter.

This should give you a little more horsepower and a little better gas mileage. Plus, it will give you much better protection.
