Agency Power Cold Air Intake Kit

Agency Powered Parts are discontinued. We have a few of these intakes in stock, but when we run out, they’re gone  the quantity shown in stock is how many we have left. Currently in stock, ready to ship!

A cold air intake kit is one of the best upgrades you can do to your Subaru WRX STI.  Turbo systems love to get a lot of air in and then move that air out as efficient as possible. So to improve the air intake, Agency Power has this complete cold air intake system with heat shield for the Subaru WRX STI.

Made here in the USA, the Agency Power Cold Air Intake utilizes a roto-molded intake tube that has been designed to increase airflow and performance without the need of an ECU tune. Each kit utilizes a high flow cone air filter to not only breathe better than factory, but is reusable for the life of the vehicle. This high flow cylindrical air filter features a much improved flow rate over stock and designed to catch more particles compared to a paper mesh design. With the new air filter, your turbocharger can breathe better than the factory intake allows. This is noticeable as you step on the accelerator and hear the turbo work (sucking air noise). Release the throttle and the factory blow off valve noise (whoosh) is more audible and keeps you entertained through the gears! 

The aluminum heat shield helps keep the air forced in from the front of the STI directly on to the filter. Used as a barrier between the engine and the filter, it also helps reduce intake temperatures. The heat shields are powder coated black and features the Agency Power “AP” logo. 

As tested on Mustang AWD Dyno the Agency Power Cold Air Intake on the Subaru WRX STI made +26WHP and +34 WTQ.

  • Gain up to 30HP and 30FT/LBS
  • Lightweight Roto-molded Plastic Construction 
  • Aluminum Constructed Heat Shield Powder Coated Black

The agency power Intake is awesome,

The agency power Intake is awesome, It does not require a tune, I had the trims checked and they are compatible for my car 2018 Sti. The ECU just has to be reset the long way. I have an agency power intake on the car prior to this purchase, purchased 5yrs ago. The price was too favorable to not buy another one when I saw it on the site. This intake does give the performance # s quoted and the testing mentioned in the listing was actually done by Vivid racing years ago on their Mustang equipment. For the 2018 Sti there is a reiforcement frame for the new stiff suspension and 19” wheel size so it has to be wormed in. I modified the intake tube and added /modified it while I was at it , so that a filter size of 3.5” front inlet can be used and this provides more filter options (ie oil,dry) and with a small bend 3.5 Alumiium tube 45* flange i fabricated that hooks up to product intake tube with an alteration with 3.5 to 3” silicone reducer . The total length of the intake tube is the same just the structuaral configuration has been altered.
This takes out the need for the worming in when installing the 2018 model . Easy in and out now.
The agency power intake provides a sweet unbelievable sound that the product comes with when installed. You feel the power that they mention and most important for this product is the torque gain. It is an entirely different car in sound and performance . If additional mods are planed the agency power intake will perform with even better numbers.
Totally recommend this product especially the metal shield which distinguishes this product simple but powerful This product exceeds the gains of any other Cold air intake products out there . Just totally AWESOME .
