EVO X Cold Air Intake Installation Instructions

EVO X Cold Air Intake Installation Instructions by EVOXTuning.com

Today we installed the new air intake system by Agency Power. This intake system consists of a Mass Air Flow Adapter, K&N Filter, and heat shield. The install took about 25 minutes to complete with only basic hand tools necessary. Please check out the install process below, as a reference on how to install this quality product.

Installation time: 25 minutes

Tools Required: 1/4″ drive ratchet, 10mm socket, 8 mm socket, philips screw driver, T20 torx driver, metric allen wrenches.

The first step: Remove the 2 plastic philips screws that hold the air intake duct in place on the radiator heat shield plate. There is also (1) 10mm bolt that needs to be pulled from the front right side of the air box. Upon removing the clips and bolt, the air box can be unclipped and the filter removed. The front of the air box will then dismount from the back half and can be pulled from the car. The MAF (mass air flow) sensor can now be unplugged, and the rear half of the air box removed from the car, after loosening the hose clamp that attaches the back of the air box to the air inlet tube.

The next step: Mount the MAF sensor in the new adapter provided by Agency Power. The direction of airflow is marked on the top of the sensor to ensure correct mounting direction. Use the supplied allen head bolts from the kit to attach the sensor to the new adapter. After the MAF sensor has been swapped to the adapter, it can be mounted in the vehicle. Once mounted plug the electrical connection back in, making sure that the harness is safely secured.
After the MAF adapter is in place the next step is to install the K&N filter. It attached with the provided hose clamp. Make sure the filter are securely mounted before you proceed.

Finally, the last step: Mount the heat shield. You will need to swap the factory mounting grommets over–from the stock air box lower assembly–to the bottom of the new heat shield. Tighten the 10mm bolt in the stock location and then snap in the factory air feed duct. You can now reinstall the philips plastic screw clips in the radiator plate and you are ready to take a test drive.

Results:
We were very, very pleased with throttle response as well as increased power on this product. You will also notice a very different sound when this part is installed. You will hear the open element filter breathe as well as the blow-off valve becoming much more audible when you let off the throttle. When pairing the intake and the blow off valve, the stock revving sounds will be replaced with the wonderful sound of performance by Agency Power.

Photos 2 & 3: Close-up of stock air box with mass air flow sensor removed. Two T20 torx screws hold the MAF sensor in place. Carefully set the MAF sensor aside. Mount the stock T20 screws in the stock air box so you will have it, in the event, you ever return the vehicle to stock. The third photo shows the Agency Power MAF adapter with the MAF sensor installed.
