Mazda 6 2.5T Front Mount Intercooler

Performance Intercooler Upgrade for the 2018+ Mazda 6 2.5T, CX-5, and CX-9

The CorkSport Intercooler for the 2018+ Mazda 6 2.5T, CX-5, and CX-9 improves cooling efficiency through its large 27x6x3.5” core and optimized fin design. Keep your boost temperatures low and power high even during back-to-back pulls in hot weather. The CS FMIC kit is a complete, direct bolt-on with no cutting or drilling for proper fitment and everything you need for installation. This means brackets, hardware, clamps, custom silicone elbows, and adapters to work with the OEM intercooler piping. Plus, it makes power on its own and is ready for any future CS mods as it will support 400 HP!

Combine the Mazda 6 Intercooler Upgrade with the Upgraded Intercooler Piping Kit for the best performance cooling package available. If you combine now you will save $50 on the complete vs purchasing the piping at a later date.

The CorkSport Advantage
Upgraded Mazda 6 turbo FMIC comparison to stock

Performance Driven

Side by side you can see that the CorkSport Intercooler takes full advantage of the space available behind the grill of the Mazda 6.

The Mazda 6 Front Mount Intercooler is 3/8” taller and 1” thicker than the OEM intercooler, providing 50% more core volume. This improves peak flow for a reduce pressure drop across the core and increases cooling efficiency for lower boost air temperatures.

Robust Construction

Unlike the stock Mazda intercooler design that uses plastic tanks that are clamped to the aluminum core, the CorkSport Intercooler utilizes CAD-designed aluminum cast end tanks that are welded to the core.

Cast aluminum end tanks were used for their improved thermal efficiency, durability, and ability to withstand high pressures, as well as the flexibility to use smooth and consistent bends, unlike sheet metal end tanks.

Modular Design

The CorkSport Intercooler Upgrade is designed to work seamlessly with the CorkSport Piping Upgrade. The piping upgrade can be used now or at a later date without issue, you decide.

Cx5 Turbo Intercooler Temperature Drop Test

Thermal Efficient Design

The entire purpose of an intercooler is to cool the boost/charge air exiting the turbocharger compressor outlet. The efficiency of intercoolers can vary drastically depending on the design and size. Let’s compare:

Four dyno runs were completed back-to-back for both the OE and CS intercoolers. The results of both showed good improvement in thermal efficiency for the CorkSport Design.


  1. Starting IC Outlet Temperature = 60 degF
  2. Ending IC Outlet Temperature = 82 degF
  3. Delta Temperature Increase = 22 degF


  1. Starting IC Outlet Temperature = 63.4 degF
  2. Ending IC Outlet Temperature = 79.4 degF
  3. Delta Temperature Increase = 16 degF

Skyactiv intercooler pressure drop test data

Balanced Pressure Drop

Unknown to most, the pressure drop across the intercooler core is the by-product of the cooling efficiency of the core; you cannot have one without the other. The goal of a high-performance intercooler is to balance/reduce the pressure drop without compromising the cooling efficiency.

In the same four dyno pulls we also recorded the pressure drop across the intercooler core and found that we were able to minimize pressure drop while also increasing cooling efficiency. This is important because, the lower the pressure drop, the more efficiently your turbocharger can provide boost pressure to the engine.


  1. Low RPM Pressure Drop = 0.7-1.7 psi
  2. High RPM Pressure Drop = 1.7-2.3 psi


  1. Low RPM Pressure Drop = 0.5-1.4 psi
  2. High RPM Pressure Drop = 1.4-1.7 psi

4 ply silicone tubing for the Cx9 Turbo

Performance Silicone Couplers

All connections between piping and the intercooler are replaced with new 4-ply reinforced silicone couplers. Silicone is ideal for boosted applications due to its high durability in high-heat environments and added ply or reinforcement reduces swelling during high boost.

Skyactiv Turbo FMIC Kit Hardware

Top Quality Hardware

Included with the CorkSport Intercooler Upgrade is all the necessary hardware, brackets, silicone, and T-Bolt clamps required for installation.

Thick 0.125” stainless steel brackets and quality hardware keep the IC core mounted and secure.

This thing is an absolutely beautiful piece. I almost didn't want to install it and just sit it in my living room so I could look at it. The reason for the 4 star review instead of 5 is because once installed, I inherited NO performance gains whatsoever (1/4 mile drag strip confirmed). In fact the best time I've ever had at the track with my 6 turbo was before I installed my intercooler and piping kit with just the intake and cat back exhaust. My guess is a tune would make a bigger difference.
Just installed the whole setup on 11/28/2020. Not bad, taken sometimes and bit confused with the metal adapter written in the MI. Just like Sean mention below, it a good mod for car performance and smoother accelerating.
My Mazda 6 is the first car I have added serious aftermarket parts to, and this Intercooler definitely strikes me as a serious modification. I installed the Intercooler along with the Intercooler Piping Upgrade. I had also previously installed the Cat-Back Exhaust, and Short Ram Intake upgrades. The change I noticed the most after the Intercool and Piping upgrade was the additional horsepower in the higher RPM range. In my novice opinion, I really think the car needs a tune to take full advantage of the modifications I currently have made. The install is TIGHT. CorkSport Engineers definitely squeezed every bit of space they could to fit the Intercooler and Piping Upgrade into the frontend of the car. The installation was pretty straight forward using the step-by-step instructions, but be prepared to spend some time making minor adjustments to get everything to fit up just right. I am happy with the purchase and look forward to getting the car tuned as well installing future upgrades.
Seriously best mod, BATs are way down, car drives smoother. Don't wait just buy it and thank me later.
