When should I change out my CAI filter?

^ Just purchase the recharge kit and it has instructions with pictures. You can probably also google search how to clean a air filter using the K&N recharge kit. It takes more time to allow the filter to actually dry, then the whole process! Good luck

^what he said. Doesn't sound like you've done it before OP. Just follow the instructions and you'll be set. I think BGB or someone else said it earlier too - don't completely soak the filter with oil when it comes to that part as you don't want any getting past the filter into the MAF or turbo.

Just make sure you don't use a air compressor hose and blow stuff out of the filter. You can damage the filter, and break apart the mesh screen. Just a soft toothbrush and the cleaning solvent in the kit works great. Rinse it out with water, not too high of pressure water. Let air dry over night, and then lightly spray the filter with the provided oil. You want to spray just enough to get the red color of the filter to darken slightly. Good luck, it is a easy and cheap fix!
