Title: Wow! It really worked!
Review: I've needed to clean my filter for a while, but opted to purchase another filter instead (My filters are another brand, not K&N) When the time came to clean or buy again, I decided to get out the old filter and test out this service kit on it. Not only did it work, I would never know that this was not a brand new filter. This kit even took care of the other filter on my car which happened to be blue. The cleaner took everything off of the old material, including the old dye. Performance wise, my vehicle feels much better, similar to when I installed the fresh air intake. I will buy again.
