Hardware Requirements: Stage 4 

This package is capable of even more power.  Below is an example of what can be done with a Protune on E85 fuel.


This was done on a 2014 Evo X MR with the Stage 4 Power Package as the only modifications!  This package can make even more power but the motor should be built for power levels not too far beyond what is shown above.

Stage 3 Power Package

This release also includes reworked Stage 3 Power Packages which now includes the Airbox with the SF Intake.  The Turbo Oil Supply Line, Turbo Gasket Set, Turbocharger, and Fuel Pump which make up the Stage 4 Power Package are also available separately.

Simply plug-in and bolt-on these components for excellent power gains, outstanding build quality and an impressive exhaust note.

Newly Added Hard Parts

mit00200ia_main-1 The C.A.R.B. certified COBB Tuning SF Intake + Airbox utilizes our custom design to optimize flow for ideal performance. The custom conical cloth filter feeds filtered air directly to the engine, while maintaining optimal intake velocity and minimizing turbulence. The COBB SF Airbox for the Evo X will help to prevent hot and turbulent air from being ingested into the engine.
mhi-tf06-18k_main The Mitsubishi FP MHI TF06-18K Upgraded Turbo for the Evo X is a direct bolt-on application that delivers dramatic increases in performance with stock-like spool and driveability. Use with the COBB Stage 4 Package and Off The Shelf map for a full furn-key solution.
fpmlssevox_main  The high flow replacement oil supply line for the Evo X vehicles are now available. This new high flow oil supply line allows plenty of oil to get to your turbo to keep you from oil starving the bearings. Included with this line is an inline oil filter to help protect your turbo from any contaminants your oil may pick up.
gsevoxset_main  The Evo X turbo gasket set can be used to replace worn or leaky gaskets on your factory turbocharger.  It can also be used during the install of your upgraded MHI TF06-18K turbo.
352450_main  AEM’s 320lph E85-Compatible High Flow In-Tank Fuel Pumps feature robust internal construction that is designed to withstand the low lubricity characteristics of ethanol and methanol fuels, and are tested to work with ethanol fuels up to E100, methanol fuels up to M100 and all types of gasoline. Its compact, short body design (65mm length) with mounting hooks also makes it ideal in universal applications that have fuel tanks with tight tolerances.

The 320lph E85-Compatible High Flow In-Tank fuel pump includes a wiring harness, pre filter and O-rings. Every AEM 320lph E85-Compatible Fuel Pump is tested to flow 320 lph at 43 PSI before it is packaged for sale.

    • We do not. While some of the components will carry over from the Evo X, the calibration will be different so a Protune would be required.


  1. Have a couple of questions:
    1. Is the graph hp atw? Just wondering since my FE is already at 303 hp atc.
    2. After Stage 4 installation, can I flash back the ECU to the stock, leaving all the upgrades in tact? I am planning to travel from Cali to Vancouver, CA.

    • Hey Armand!

      The graph is indeed a representation of wheel horsepower. Utilizing the factory ECU tune is NOT recommended as there are changes necessary for the fuel injectors and intake that the factory tune cannot account for.


    • Hey Andrew, we were wanting to show the overall capabilities of this package utilizing E85. Stage 4 power against stock can be referenced in the chart below. You’re essentially looking at very similar response to stock with gobs more power up top.

  2. Once upon a time on your website you had all of the stage three components into one solid package. Is that package forever gone or is there a way to re obtain that? I imagine buying all the parts separately would be more expensive than the package would have been at the time.
