And of course, my hubby would always check the care every morning and before every trip to ensure a smooth and safe travel for all of us. He would check the tire pressure, brake fluid, engine oil, steering wheel fluid, the radiator coolant and anything that needs to be checked. Every two months, he also have the car change oiled, tuned up and replace the fuel filter, oil filter and the air intake which he believes affects the performance of our car. And yes it is true, reading from an auto magazine, cold air intake keep your ride humming with with efficiency, gives you that thump in speed and turns hot dirty into cool clean breeze for your engine. I guess my hubby is right on this every time he goes for our car maintenance.
