Check your spark plugs and wires. Your ignition system works hard. Spark plugs fire millions of times, and inefficient spark plugs can cost you performance and fuel mileage.
Check all your caps. Gas caps, radiator cap, brake fluids and more. Anywhere fluids are poured should be checked for a tight seal. This will keep out water and debris and keep your car running smoothly.
Clean your headlights. Road salt, harsh weather, grime and other debris can leave your headlights cloudy and dirty. Take some extra time and clean them up to give yourself greater visibility for night driving. You may need to have them professionally cleaned.
