The kit will also work if you have a tuned engine, and might even offer more enhanced performance.

      Reusable Fine Filter. The K&N Series 77 High Flow Performance cold air intake is built from epoxy-coated aluminum fins wrapped around top quality cotton gauze soaked in special oil. This allows the filter to grab particles from the air quickly, and it makes it entirely washable. The filter is easy to maintain and can be used for tens of thousands of miles in standard conditions before it needs cleaning.

      Tough Efficient Build. The K&N Series 77 High Flow Performance cold air intake is built for strength and efficiency. It features a smooth intake tube that's made from chromed metal for a path of least resistance for incoming air. It comes with a tough heat shield that holds the whole unit in place while protecting the intake filter from hot air and debris. The filter is made from epoxy aluminum and designed for long-term weather resistance.

      One Hour Install. This cold air intake set goes on in an hour with minimal work or tools. Just remove the old parts and bolt in the new ones and you're done.
