Using this Injen cold air intake is straightforward. First, find a well - lit and stable workspace. You'll need basic tools like wrenches. Carefully remove the old intake system following the standard procedures for your Honda Civic model. Then, install the new Injen cold air intake in place, making sure all connections are secure. The custom heatshield can be easily attached as well. When it comes to maintenance, check the air filter regularly. If it looks dirty, clean it according to the instructions provided. Also, make sure to keep an eye on the intake tube for any signs of damage or wear. In cold weather, there's no need to worry about the intake's performance, but it's a good idea to check for any ice buildup. Avoid using harsh chemicals on the intake components.
