Upgrade your Injen Technology intake system with a hydro shield. A hydro shield is a universal component which will protect your new intake from contaminants. It also has a hydrophobic treatment which will help repel water. Although it does not make your filter water proof, it is an added layer of protection. You can also help extend the life of your new intake system with a cleaning kit by Injen. Their cleaning / oil kits can be used directly on the cotton-guaze filter to remove any build up after use.
