Well Satisfied with K&N Cold Air
You won't believe how dirty your filter is!

I just revived this in the mail, as I thought it would be good to clean my air filter for the first time. It had been about 20k miles. I bought this kit because I already trusted K&N, mostly due to the fact that they have one of the best oil filters out there. Now my intake filter is not K&N, it's from ChromeIntakes. You don't have to have a K&N filter to use this! Anyway, I used the cleaner as instructed, and you won't believe all the nasty dirt that just poured out of it, non of it visible to the naked eye until using this product! The suggested cleaning time is every 50k miles but I would do this every month or every other if your car is a daily driver. The only reason why this is not 5 stars is because I did not receive a service decal as stated in the product description.
