Installation Requirements
Proper installation of this kit requires the use of Digital Technician by a factory-trained technician at a Harley-Davidson dealer.
This kit requires the use of LOCTITE 243 MEDIUM STRENGTH THREADLOCKER AND SEALANT (BLUE) (99642-97) and Air Cleaner/Degreaser (H-D Part Number 99883-88T ), both available from a Harley-Davidson dealer.
Rider and passenger safety depend upon the correct installation of this kit. Use the appropriate service manual procedures. If the procedure is not within your capabilities or you do not have the correct tools, have a Harley-Davidson dealer perform the installation. Improper installation of this kit could result in death or serious injury. (00333b)
This instruction sheet refers to service manual information. A service manual for this year/model motorcycle is required for this installation. One is available from a Harley-Davidson dealer.
Kit Contents
See Figure 3 and Table 1.
This Screamin' Eagle Ventilator Performance Air Cleaner is intended for high-performance applications only. This engine-related performance part is legal for sale or use in California on pollution controlled motor vehicles. Engine-related performance parts are intended FOR THE EXPERIENCED RIDER ONLY.
The air cleaner contained in this kit is designed to perform with this kit only. Any other combination of components is not confirmed to be legal for street use.
To prevent accidental vehicle start-up, which could cause death or serious injury, remove main fuse before proceeding. (00251b)
  1. Remove main fuse. See service manual.
  2. Remove the existing air cleaner. See service manual. Discard the parts.
  3. See Figure 3. Remove and discard the induction module bracket (A).
Air Cleaner Installation
Use only supplied air cleaner cover. Use of another air cleaner cover could cause element failure and detachment of the air cleaner cover, which could distract the rider and result in death or serious injury. (00596b)
When servicing the air cleaner, apply LOCTITE 243 MEDIUM STRENGTH THREADLOCKER AND SEALANT (BLUE) (99642-97) to the threads of all fasteners.
1. Remove the liner from the adhesive backing of the gasket (10). Carefully position the adhesive side of the gasket to the backplate, aligning to the equally spaced screw holes. Press the gasket firmly into place.
2. See Figure 3. Insert the two breather bolts (8) through the air cleaner backplate (7). Remove the adhesive backing on the two intake tube gaskets (6). Install on the induction module side of the backplate.
3. Apply threadlocker to the breather bolt threads and the mating tapped holes in the cylinder head. Position back cover over backplate.
4. Thread the bolts into the cylinder head, but do not tighten.
5. Thread the air cleaner mounting studs (1) all the way through the backplate (8) until the screw threads are captured in the induction module. Leave fasteners loose.
6. Secure the three air cleaner studs. Tighten.
Torque: 6.2–6.8 N·m (55–60 in-lbs) Hex head screw
7. Alternately tighten the two breather bolts. Tighten.
Torque: 13.6–16.3 N·m (120–144 in-lbs) Hex head bolt
8. Install the adapter plate assembly (2) to the mounting studs (1) using hex socket button head screws (with threadlocker applied). Tighten.
Torque: 4.1–6.8 N·m (55–60 in-lbs)
9. Assemble breather plugs (9) to breather bolts (8).
10. If removing the Original Equipment (OE) intake you must apply the provided Warning Label in a clearly visible area. We suggest attaching the sticker to the following:
a. Softail: Right side lower fender
b. Dyna: Right side swing arm.
Air Cleaner Element and Cover Installation
Whenever the air cleaner cover is installed, apply LOCTITE 243 MEDIUM STRENGTH THREADLOCKER AND SEALANT (BLUE) (99642-97) to all air cleaner cover screws.
1. See Figure 3. Secure the air filter element (3) to the adapter plate assembly (2) using three hex socket button head screws (5). Tighten.
Torque: 6.2–6.8 N·m (55–60 in-lbs) button head screw
2. Remove the liner from the adhesive backing of the air cleaner emblem (11). Carefully position the adhesive side of the emblem to the front cover (4). Press the emblem firmly into place.
3. Assemble wire mesh (14) and filler plate (15) to front cover.
4. Apply threadlocker to all cover screws (13) and mating tapped holes in back cover (16).
5. See Figure 1. Install front cover plate with wire mesh and mesh filler plate using 1/4-20x2.5 in. SHCS screws provided. Alternate tightening in a star pattern until all six fasteners are snug. Then one-half turn (180 degree) each in same pattern. This is to avoid crushing the element. If necessary, another one-quarter turn (90 degree) but no more.
Figure 1. Fastener Tightening Sequence
Riding a motorcycle equipped with an exposed air filter element under rainy conditions IS NOT RECOMMENDED.
  • If parked, water could enter the engine.
  • If moving, enough water could be sucked in to cause engine misfiring.
Slip the rain sock (12) over the air filter element under these circumstances.
Final Assembly
  1. Install the main fuse. Refer to the service manual.
ECM Recalibration
You must recalibrate the ECM when installing this kit. Failure to properly recalibrate the ECM can result in severe engine damage. (00399b)
Have a Harley-Davidson dealer download the new ECM calibration using Digital Technician™.
Air Cleaner Element Maintenance
When servicing the air cleaner, apply threadlocker to the threads of all fasteners.
  1. Remove the air cleaner cover and inspect the filter element every 8,000 Km (5,000 mi), or more often under dusty conditions.
  2. NOTE
    The use of cleaning, drying or oiling methods or products other than those shown will damage the filter and void the manufacturer's warranty
    K&N® Air filter Cleaner is available from a Harley-Davidson dealer, either alone (1 qt/0.95 L sprayer bottle, 99883-88T ) or a 12 fl oz/0.35 L sprayer bottle as part of the Filter Care Service Kit ( 99850-92T ).
    K&N Air Filter Oil is also available from a Harley-Davidson dealer, either alone (12.25 oz/347 gram aerosol can, 99882-88T ) or a 6.5 oz/184 gram aerosol can as part of the Filter Care Service Kit.
    DO NOT OVER-OIL THE AIR FILTER. Over-oiling may interfere with the proper performance of the engine and/or certain engine components. If oil is still draining or dripping from the filter media twenty minutes after oiling, clean and oil the filter element again.
  3. To clean the element:
    1. Disassemble front cover assembly screws (13).
    2. Disassemble air filter element screws (5). Remove element (3) for cleaning.
    3. Tap the element to dislodge any loose dirt, then gently brush with a soft bristle brush.
    4. Spray air filter cleaner liberally onto the cotton filter media and let soak for ten minutes OR roll and soak the cotton filter media in a shallow pan of air filter cleaner. Remove immediately, and let soak for ten minutes.
    5. Rinse off the filter media (flowing from the clean side to the dirty side), with low-pressure tap water.
    6. After rinsing, shake off all excess water, and let the filter media air dry. DO NOT use compressed air or a heat gun to speed drying.
    7. After the filter media is completely dry, EITHER spray air filter oil along each pleat, once only, holding the spray nozzle approximately 76 mm (3 in) away from the media, OR carefully use a squeeze bottle to deposit oil along each pleat, once only. Let the oil absorb into the filter media for 20 minutes before proceeding. After twenty minutes, inspect the filter media. Carefully apply oil to any remaining visible white spots on the filter media. Allow to absorb.
  4. Install the air cleaner element and covers.
