This Install Guide is intended to help with the installation of the Agency Power Cold Air Intake Kit on the 2013-18 Subaru BRZ / Scion FR-S / Toyota 86.
INSTALL DIFFICULTY: 
STEP 1 – Unclip the Mass Air Flow Sensor Harness and then loosen the 2 screws. Remove the Mass Air Flow Sensor. Reinstall into the new intake tube with the 2 supplied screws.
STEP 2 – Loosen hose clamps at throttle body, air sound tube and air box. Unclip and pull out the air vent tube. Then remove the air tube.
STEP 3 – Remove the 2 bolts securing the air box. Pull air box from car and remove the rubber grommets to swap to the new intake box. (Push steel sleeve out and grommets with then slide out.)
STEP 4 – Place new air box into engine bay. Very tight fit. Bolt air box down with factory bolts. Start with back bolt to tighten then move to front bolt.
STEP 5 – Install air filter and couples on to intake tube for best fit. Place filter end into the air box and bolt half of shield into place. Secure the throttle body coupler and tighten. Install the second half of shield and tighten bolts.
STEP 6 – Tighten up throttle body coupler, air sound tube couplers, re-install vent tube into grommet and clip mass air flow harness together.
Finished – Install Complete
If you run the box you like boys. That was not easy to install at all. Also had to waller out the hole for the small tube by the sensor cuz that was not going in at all. I didn’t put the box on. I couldn’t get it all together with the box. If you want your car to sound sick as tits don’t put the box on(if you don’t mind the dope sounds it makes). I give it a 4 outta 5. Recommend for sure!
Sorry to hear about your experience with the installation! We will look into that and see if it is a reoccurring issue.
The fit is super tight but I got it on with some wrestling. It had a great induction noise however after 3 days I got a code from the ECU giving me Lean codes. So rather than risking any damage to the engine itself I took the car to a dealer certified mechainc and had to reinstall the factory intake. The 3 days I had it, it was awesome though. Now it’s a great piece I look forward to putting on when I can tune the car.
Hey Edward,
Sorry to hear about the trouble. We have not seen any CEL’s with the stock tune and the code typically indicates unmetered air getting into the system in some way. This can be as simple as a vacuum leak after the MAF, the MAF itself could be dirty, or even the O-ring for the MAF may be damaged.
