Remove any storage boxes from the cargo. If you have a tire rack, release and lift it to the open position. Any other accessories in the cargo area preventing removal of the rear scoop will need to be removed as well

Prepare to remove the rear scoop from the vehicle by unfastening the two T27 screws and the rivets on each the passenger and driver side.

Remove the rivet accessed from inside the vehicle that fastens the air inlet grille to the scoop. If you don’t have the cold air roof scoop that connects to the rear scoop, you can skip to step 7. 

If you have a tire rack, also remove all of the rivets at the base of the roof scoop that fasten to the rear scoop. 

Remove all of the screws that fasten to the rear cover panel of the roof scoop at the top and pull off the panel. 

Once the rear roof scoop cover panel is removed, unfasten the now accessible screws that secure the roof scoop to the vehicle. 

Pull the scoop assembly off the vehicle. If you have a tire rack, you will drop down the roof scoop into the rear scoop and wiggle it out.

Unfasten the 4 bolts securing the OE baffle wall to the vehicle accessed from the rear of the vehicle using an M10 socket.

Remove the T27 screw accessed from the interior of the vehicle next to the air grille above the seat that fastens to the baffle wall.

Push the rubber air intake tube out of the baffle wall and remove the baffle wall.

Unfasten the hose clamp securing the rubber intake tube to the OE airbox and remove the tube.

Clean the surface of the intercooler support and then stick the 1/8" thick foam adhesive on the surface as pictured.

Cut this circular rib on the underside of the cold air cover as pictured using a flush cutter. This will give more room for the separator.

Use the provided replacement baffle wall to line up on the underside of the rear roof assembly to see where to apply the 1” thick foam. Clean this surface and apply the 1" thick foam as pictured, cutting any excess.

Put the supplied clip nut onto the replacement baffle wall into the position shown.

Install the separator into position by first angling the tube outlet down near the suspension, then swinging the rear end of the separator to fit the fan exhaust portion around the intercooler support. Carefully twist the replacement baffle wall around the separator while installing the separator into position. 

The separator vortex tubes will be horizontal and the inlet front face of the separator will be angled relative to the vertical wall of the intercooler support when in position as pictured.

Install the front bracket reusing the M10 OE baffle wall screws and washers to fasten to the vehicle and the supplied screws and washers to fasten to the separator using an M4 allen key. Do not fully tighten until the rear bracket is installed.

Install the rear bracket by removing the M10 screw fastened to the tank baffle wall, then reinstalling it to the bracket and fastening the supplied screws and washers to the separator using an M4 allen key. Use the supplied rivet to secure the baffle wall to the bracket.

Install the previous removed T27 screw from the inside of the vehicle to fasten to the clip nut on the replacement baffle wall.

Install the supplied tube between the airbox and the separator. It is recommended to put the step coupler pushed as far as possible onto the OE airbox with its respective hose clamps, and the other coupler all the way onto the tube with its clamps. Then once the tube is in position, slide the couplers so that they line up with the indicators on each component (the tube has beads on each side for the couplers, and the separator and airbox each have indicating bumps).

To start wiring and gain access to the busbar, start removing the passenger seat from the vehicle by removing the front two anchor bolts.

Next, flip the seat seat cushion by pulling up on the rear of the cushion. Remove the now accessible rear anchor bolts of the seat.

Pull the back of the seat forward to remove the seat belt anchor bolts.

Remove the seat from the vehicle, and then unfasten the T27 torx screw pictured.

Swing the center console panel up to gain access to the wiring.

Identify the supplied main wiring harness, remove the three nuts from the busbar to then connect them: Orange wire labeled “ACC” at the top post,  the black wire labeled “GND” on the bottom post, and lastly the red wire labeled “BATT” in the middle post. Retighten the nuts.

Route the end of this main wire harness through the center console through the hole that is open to the rear of the vehicle. Shining a light through can help identify the opening.

Follow the path of an OE harness going to the driver side of the vehicle along the firewall. For now leave the harness near the airbox un-zip tied.

Disconnect the rearmost ignition coil harness from the passenger side.

Locate the ignition sensor harness and remove the gold screw to prepare to install it on the vehicle.

Install the ignition sensor onto the positive ignition coil wire (brown) placing it about 1” away from the connector. Make sure that the top clip piece touches the bottom clip piece on the inside. Use zip ties on each side of the connector to ensure it does not slide up or down the wire during use. Route the ignitor sensor towards the OE air box but do not zip tie.

This is what the sensor will look like with the zip ties around the wire. 

Ignore the color of the wire in this photo

Locate the Y splitter harness and familiarize yourself with it using the picture for this step. One side will have a single connector that connects to the scavenge fan from the PS. The other end has two connectors: one square 4 pin connector that connects to the ignition sensor, and one flat 3 pin connector that connects to the main power harness.

Connect the main power harness to the remaining connector on the y splitter harness. The main harness is the one that was routed from the busbar through the center console.

Connect the single 3 pin connector on the single connector end of the Y harness into the connector from the scavenge fan coming from the main Particle Separator unit. The scavenge fan connector comes from the rear side of the separator (on the bottom right of the side with the white S&B logo).

Plug the square 4 pin connector on the Y harness into the connector on the ignition sensor that you put on the ignition coil harness earlier.

To ensure that everything is installed correctly and there are no problems with any part of the electrical system, we need to run a test to verify the function of the whisper quiet fan technology system. If your particle behaves as these tests describe, the electrical system is functioning correctly. If the separator does not act as described, please watch our electrical system troubleshooting video to determine the cause of the misbehavior before moving on. Make sure all of the harnesses are not near any moving parts on the vehicle prior to testing

1. Turn the ignition to the key on position. The fans on the particle separator should be at 20% speed and should barely be audible.

2. Turn the ignition on. The fans should be at 50% speed and barely be audible over the engine idle noise.

3. Rev the engine to a constant 3000 rpm for 5 seconds and then take your foot off of the gas. The fans should build to and stay at max speed during the 5 seconds, and decelerate back to 50% speed 2 seconds after you let your foot off of the gas.

After confirming everything is functioning correctly, it is time for cable management of the different harnesses. Starting at the separator and working backwards from there, we decided to zip tie the y harness in on the firewall near the airbox.

We then zip tied the ignition sensor to this coolant hose, jumped to the firewall, and met with the y harness bundle.

Then we began zip tying the main harness along the pictured OE harness, pulling any excess back into the center console bundle and zip tie.

At this point, verify the wires are all secure and in good position, then refasten the removed screw after swinging the center console panel back down.

Put the seat into the vehicle and fasten the seat belt anchor bolts to 64.5 +/- 6.5 Nm (48 +/- 5 lbf-ft).

Fasten the rear anchor point of the seat to 64.5 +/- 6.5 Nm (48 +/- 5 lbf-ft).

Fasten the front anchor point to 24.5 +/- 3.5 Nm (18 +/- 3 lbf-ft).

Put the rear scoop assembly back on to the vehicle. If you have a tire rack and roof scoop, use a similar method to the one that you used to remove it (drop the roof part of the scoop into the rear scoop and wiggle it around the tire rack as necessary). 

Fasten the rivet and screw on each side of the scoop assembly. 

If you have a roof scoop, refasten it to the roof, its base to the rear scoop, and top roof scoop panel.

Push in the front air grille rivet to secure it to the rear scoop.

S&B recommends that you apply a layer of waterproof grease, such as made by Bel-Ray or Super Lube, on the inside flange of the stock air filter to keep dust from bypassing the seal.

Your Particle Separator requires very little if any maintenance depending on where you drive; however, you should check to make sure that none of the openings in front of the Particle Separators are blocked by mud or other debris each time you exit the UTV. You should also make sure the scavenge fan is operating properly. To do so, simply check to make sure the fan is still blowing out air (for about 15-20 seconds) when you turn off your UTV as this is a normal condition. If the fan is not blowing out air or the airflow seems lower than when you initially installed your system, please contact S&B tech support. To clean your Particle Separator, review the cleaning instructions below.
