K&N Filter Replacement
The R&R of the stock air filter with the K&N drop-in replacement filter is a pretty simple modification to make, and will improve air flow.

Tools required: Flathead Screwdriver

Time to complete: 5 minutes

Cost: Approx. $35.00 Available at myFordPerformance.com

Instructions:

1. Unscrew the 4 screws on the top of the air box.
2. Slide the air box top out of the way.
3. Remove the stock filter.
4. Install the new filter.
5. Put the air box top back on.
6. Tighten the 4 screws.

Note: This K&N filter is the factory pre-oiled drop in filter. There is no need to pre-oil the filter yourself prior to installing. Check to make sure the K&N filter you use says "factory pre-oiled" and refer to the instructions that come with the filter...
