I am glad to have fitted my S-Type v8 with this air filter. Pure performance is the result. Sheer acceleration with lightning fast overtakes, not to forget mentioning incredibly smooth gear shifting. A dream come true!

I have been using this same filter for 6 years. I use the cleaning system once a year. This is a perfect system. My Lincoln has more horsepower than it did before using this filter.

I gained 5mpg city and 8mpg highway. Best investment for the price.
