Here, you are looking at the COBB Turbo Inlet for 2015-2021 Subaru WRX.

This inlet is constructed of cast aluminum, a much-needed upgrade over the failure-prone factory piece.

The inlet ID has been expanded to 70mm, a 5mm increase compared to stock and the outlet is 2mm larger than stock, matching the factory compressor inlet of 50mm. Features include mounting provisions for either stock or COBB Electronic Boost Control Solenoids, and threaded ports to accept factory-sized PCV and EVAP fittings (included). We replace the brittle factory BPV connection with a more robust reinforced silicone coupler to eliminate a common source of air leaks. A captive o-ring is placed on the turbocharger side for leak-free installation.Flats on either side of the inlet allow for the addition of auxiliary pressure sensors, temperature sensors, etc.

The factory turbo inlet on the 2015-2021 Subaru WRX is made out of hardened plastic and is prone to failure after years of heat cycling. Cracking in the factory piece or connectors can lead to troublesome air leaks that are difficult to diagnose. The COBB Turbo Inlet is more robust and offers a measurable airflow increase over stock.

Quick Details:

  • Cast Aluminum Construction
  • Maximizes Airflow to Turbocharger
  • Directly Replaces Failure Prone OEM Components
  • Port Matched to Compressor Inlet
  • Compatible With COBB OTS Maps and Packages

    Unexpectedly necessary

    I wasn’t planning to purchase this upgrade but am very happy I did. I changed the TMIC, charge pipe, and added a 3-port BCS, and it was recommended that I change this as well while I’m down there. The part is super high quality and finished off these modifications nicely. Highly recommend!


    Thank you for the 5 Star Review and added Pic! you are 100% right especially when adding and replacing the mods you have! The Cobb Cast Aluminum Turbo Inlet is stronger than the factory plastic that tends to crack and break! It increases airflow which in turn increases HP! How can you go wrong with better reliability and performance!


    COBB is quality

    This turbo inlet is a quality piece. Install was easy. Old style Company23 bpcs mounts perfect with the short screws provided and has plenty of room. No voids or pockets, matching the inlet size and opening the whole thing up definitely makes a difference. Very happy with purchase. Would recommend. Plastic one will eventually give you problems. Car seems to run better all the way around too. I have lots of mods with custom dynotune and no problems. All numbers safe. Spools faster and sounds different. Like I said happy with purchase. Thanks again Subimods!


    Thank you for the extensive 5 Star Review! You said it all! The COBB Cast Aluminum Turbo Inlet is definitely far above the plastic OEM version! The design and quality is by far superior!


    Great Replacement

    I had to take off my oem inlet when doing my headers/turbo and during the process the plastic piece actually broke. The cobb unit is 100x more durable and comes with a slight performance and sound improvement. You don’t have to worry about it breaking ever again


    Thank you for the 5 Star Review! The COBB Cast Aluminum Turbo Inlet is a great way to replace the factory plastic piece that as you found out has a tendency to crack and break! The design maximizes airflow to the turbo increasing performance and drivability!


    Price Brandon

    So far so good, definitely less turbulence when I accelerate.


    Thank you for the 5 Star Review! The COBB Cast Aluminum Turbo Inlet is a great mod for avoiding the prone to cracking plastic! It also allows for better flow by opening the inlet by 5mm and the outlet by 2mm! This leak free install gives you assurance and performance!
