Using the S&B KF - 1074 intake replacement filter is straightforward. First, make sure your truck is turned off. Locate the old filter in your S&B Cold Air Intake Kit and remove it carefully. Then, insert the new S&B KF - 1074 filter in its place. For cleanable filters, when you notice a lot of dirt on it, use the S&B 88 - 0008 Cleaning Kit to clean it. Follow the instructions on the cleaning kit. Remember, dry filters can't be cleaned, so once they're full of dirt, simply throw them away. Always check your filter regularly, especially if you drive in dirty or dusty conditions. This will ensure your truck's engine gets clean air and performs at its best.
