        Hi Jb, I'm happy to help you! Just as you did with the air filter, use the owner's manual to find your crankcase breather filter. If it is encased in a housing, remove the clips to access the filter. You need to determine if the filter is the only thing needing replacement or if the inner holder goes as well. Use a screwdriver to separate the two if you only need to replace the breather filter. Remove the old filter. Installation is simple. Attach the new breather filter with retaining clips. Just make sure the placement is correct. Put the filter back into its housing, then reattach the cover on the filter hosing. Make sure everything is securely in place before operating your car.
