Parts Description:
This section describes each part and any special features of each part that need to be noted to assist with installation. All parts will be referred to during installation by the names used in this section.
The Lid: This simple to install lid replaces the stock lid and conceals and protects the high flow air filter that comes with the kit. It also has an extra air flow port to provide more cold air from the front of the vehicle for a slight charge effect.

Installation Overview:
Installation is very simple, it is separated into three parts: Removing the Stock Intake, Preparing the Rapid Flow Cold Air Intake for installation, and Installing the system. The com-plete installation of the Rapid Flow Cold Air Intake system should total about 20 minutes. The assembly diagram below shows how the parts of the intake fit together in sequence.

Filter Maintenance:
The intake system should be cleaned at least once every three months; in dusty climates the filter should be cleaned more often. Use a prefilter to extend time between cleaning. Cleaning the intake is a two part process, the first part of the process involves the physical cleaning of the filter with soap and water and the second part involves oiling the filter. To properly clean the filter, a Bully Dog clean-ing kit should be used. Cleaning kits are available at any Bully Dog dealer.
PART 1, CLEANING THE FILTER:
1. Remove filter from filter housing. Clean the filter housing if necessary.
2. Begin the cleaning process by ridding the filter of any dirt by lightly tapping it. Then brush away any loose particles with a soft-bristle brush. This step can usually be avoided with the use of a prefilter.
3. Spray cleaner generously over entire filter and let soak for 10 minutes.
4. Thoroughly rinse the filter with regular tap water (avoid high-pressure hoses). Flush from the inside out or clean side to the dirty side to prevent dirt from entering the filter.
5. Let the filter air dry before oiling, do not use any method to speed up the drying process. Using a blow dryer or compressed air can cause the filter to disfigure which would then allow particles to pass through the filter.
PART 2, OILING THE FILTER:
1. Apply a small amount of oil to the soft bristle brush and spread the oil over the filter. Be sure to apply a small amount of force so not to damage the filter element.
2. Continue applying oil to the filter using a soft bristle brush until the entire filter is covered in an even amount of oil, just enough to give the filter a solid blue color. Apply enough oil to make the filter a solid and uniform blue, but do not go beyond that.
3. Allow oil to sit for 20 minutes. Re-oil any dry spots that appear. Do not oil filter excessively. Exces-sive oiling can cause damage to intake sensors.

Bully Dog PreFilter (Part # 51200-8 for your intake)
The time between scheduled filter maintenance can be extended. Using a prefilter will prevent all large debris from getting into the ribs of the filter. When using the prefilter, only fine dust particles make it through the prefilter and onto the exterior of the filter. Thus when using a prefilter, scheduled cleaning easy much easier and filter life is positively effected.
AIR FILTER PREFILTER
• Extend Time Between Cleanings
• Hydrophobic Material Repels Water
• Protects Cone Filter from Large Debris
• Maintains Filter Airflow Between Cleanings

The OEM air intake sensor does not fit in the Bully Dog air intake tube because it is a different shape.
Check the year of the vehicle, the 2011 and 2012 Ford F150 3.5L ecoboost have different air intake sensors which are dramatically different in shape and size. Bully Dog part number 51202 only fits the 2011 F150 Ecoboost.
