Air Box Preparation:

Loosely install velocity stack into cone filter

Place the loosely attached air filter and velocity stack assembly into the air box. Rotate the band clamp so that the screw is easily accessible in the air box.

Attach the MAF housing to the velocity stack by aligning the holes through the air box with the (4) socket head cap screw bolts. Torque bolts to 11.2 in/lbs or until snug.

Loosely attach the air box lid with 8 of the 10 button head cap screw bolts, carefully working your way from one side of the box to the other.

Once all bolts are placed through the air box lid's holes, tighten to 24 in/lb or until very snug. (Blue Loctite is not a bad idea either)

Loosely attach the air box bracket with the flat tab facing down using the remaining 2 of the 10 button head cap screw bolts. Leave these bolts loose so that the bracket can slide from side to side for optimal fitment.

Removal of Factory Intake System:

Disconnect the the battery by removing the positive terminal and carefully placing this to the side.

Remove the factory intake hose by removing the 2 hose clamps at the very ends of the intake hose assembly using a flathead screwdriver. Only the clamp that attaches the hose to the turbocharger inlet pipe and the clamp that attaches the corrugated inlet hose to the air box need to be removed. Remove the vacuum line attached with the hose clamp and the 2 10mm head bolts that attach the Evap purge valve to the plastic housing.

Disconnect the MAF sensor by pressing on the clip and pulling out.

Remove the MAF sensor wiring harness from the retaining clips and casing by using a flathead screwdriver to release the detents. Pull this harness and its exposed wires to the side.

Remove the MAF Sensor from the factory MAF housing by using a Phillips Head Screwdriver.

Remove the two 10mm head bolts at the front of the air box.

Remove the 10mm head bolt at the back of the air box that goes through the rubber mount.

Remove the 10mm head bolt located on the right side of the air box between the ECU using an extension.

Remove the air duct seal by releasing the tabs. Usually these can be removed by pulling to the (left) side to detent the tabs. A flathead screwdriver may need to be used if this becomes problematic.

Lift up on the rubber tab on the air box seal using a flathead screwdriver.

Lift on the air box to remove the air box assembly from the engine bay. Air box may need to be wiggled release from the rubber locator.

Remove the rubber mount on the back of the factory air box by pressing down to slide out the metal sleeve in the middle. The rubber grommet will then be able to be pressed out.

 

[PRL Motorsports]

Reinstall this rubber mount and sleeve the same as it was removed.

Remove the rubber locator grommet on the bottom of the factory air box. Use a flathead screwdriver if needed.

Reinstall the rubber locator grommet on the bottom of the High Volume Air Box the same as it was removed. Lubricant can be used if necessary.

Installing the High Volume Intake System:

Install the MAF sensor into the billet MAF housing using the 2 M4 socket head cap screws. Torque bolts to 5.9 in/lbs or until snug.

Take the supplied convoluted tubing and place it over the now exposed wires on the MAF sensor wiring harness. Electrical tape this to make a weather-tight seal.

 

[PRL Motorsports]

Route the MAF sensor wiring harness under towards the center of the engine bay as far as possible (without pulling) and place the High Volume Air Box into the engine bay. Make sure to press down on the lower locating grommet to pop into place.

Plug the MAF sensor into the harness.

Place the #44 hose clamp onto the turbocharger inlet pipe side first before installing the silicone inlet hose.

With the air box still loosely installed, loosely attach the silicone inlet hose to the billet MAF housing with the #52 hose clamp loosely installed onto the hose.

Place the small vacuum nipple into the silicone inlet hose.

Slowly work the turbocharger inlet side of the silicone hose onto the inlet pipe by pulling back on the silicone.

Place the Evap purge valve to the supplied billet bung.

Tighten down the flanges using the factory 10mm head bolts.

Rotate the Evap flange like so to avoid rubbing. Tighten the #8 and #20 clamps until snug.

*Trimming of the evap portion of the silicone (And/or vacuum hose) may be required up to 1/2” for evap assembly to clear hood.

 

[PRL Motorsports]

Align the rubber mount at the rear of the air box with the hole on the chassis. Tighten down the 10mm head bolt.

Tighten the 2 10mm head bolts at the front of the air box.

Tighten down the 2 button head cap screws at on the air box bracket.

Attach the factory air duct seal to the High Volume Air Box by pressing the clips in.

Double check all connections to ensure that everything is tight. Address any necessary issues. Once everything is finished, reconnect the battery.

Thanks for the guide! Looks pretty straight forward. Are they scheduled to start shipping this week?

Jeez ok and to clean the filter we have to back it all out?

 

[DuneShoot]

Nice write up, thanks!
Not looking forward to removing most of that to clean the filter but that's the way it is

 

[fk8mike]

hope my dealer has one for me

 

[frtorres87]

I’m ready for mine to arrived

Not quite.....
Something you do once every 2 years if that....hardly anything to cry over

How close is the turbocharger inlet pipe to release? I've already ordered the High Volume Intake System, but after seeing how involved the install is, I'd rather not have to disassemble things again to install the inlet pipe.

 

[boosted180sx]

it looks like a lot of work but it's really not so bad. I can remove the factory intake in like 10 mins.

I wouldn’t throw that number out there because It all depends on where you live and how you drive. For my drive cycle I’ll be cleaning it every 6-8 months. This ain’t my first rodeo.
