Injen Hydro Shield

Does the job!

I received my hydro shield about a week ago and I immediately took it out of the packaging and straight to my kitchen. I figured i would test it. I put it around my fist and put my hand in water and WaLa my hand was dry. I also held it under a run faucet and discovered in order for water to get through, the water hitting it would have to be very concentrated with a bit of pressure. So installed it on my Focus and there has been ALOT of rain here lately and because of the Injen HydroShield I have had no problems. Thanks INJEN for a quality product! View more reviews...

Regular Maintenance

original filter had been in place for 4 yrs with nearly 50,000 miles on it. i noticed a decline in performance & fuel economy. ordered a replacement filter, easy install and back to good running health in no time. K&N is GOOD for your engines. I would recommend it to anyone. View more reviews...

What Do Air Filters Do?

How Air Filters Work The internal combustion engine in your vehicle is really just a big, complex air pump. Air gets sucked in, mixed with fuel, burned and sent back out in the form of exhaust. But since air around motorways tends to be dusty, dirty, debris-laden, there needs to be a filtration device to […] The post What Do Air Filters Do? appeared first on AutoAnything Resource Center.
