    5.0 out of 5 stars Fits perfectly on the jeep Wrangler jk K&N snorkel filter.
    Reviewed in Canada on November 5, 2022
    Works great for my Jeep Wrangler jk k&n snorkel. I was driving near a lot of construction sites and with and my filter got absolutely covered in fine dust. I don't trust that filter to filter that and it got covered way too quickly. It was also annoying to clean all the dead bits of bugs out of the filter since I drive up into the country a lot. This was purchased out of necessity to extend service life and to keep the filter from clogging constantly. I had better peace of mind knowing I wasn't sucking in concrete dust into my motor too. A bit expensive but fits perfectly onto the filter and does the job.
