4.0TT Intake Upgrade
The largest intake system that's available for the 4.0tt platform with a true full 2.5" intake runner all the way to the turbo. Inlet depression on the stock turbo can reach 750mbar while our inlet pipe doesn't drop below 900 resulting in a free 3-4psi on the top end. 30-40hp gains consistently at redline. 5 axis machined inlet snouts are welded to mandrel-bent tubing specifically designed for this application. Fits S6 S7 RS6 RS7 4.0TFSI applications. This does NOT fit the D4 S8.
*If purchasing for model A8, please purchase our S8 intakes*

Turbochargers
Our SRM1K Billet Turbochargers are the result of years of research and development bringing the ultimate drop in Turbocharger solution to the 4.0TFSI platform. These have been powering our Flagship and Development vehicles for years.
Limitless top end with mind numbing boost numbers.
Why Xona? It's simple. They're USA made, rebuildable, and offer the highest possible performance in this form factor. Xona Turbochargers power our flagship and R&D vehicles making upwards of 1200WHP.

SRM Air to Air Intercooler with
Integrated Port Injection
One of our flagship products, and first to market in the 4.0TFSI world, the result of years of development and iteration, is the 4.0TFSI A2A with Port Injection offering from SRM.
This gorgeous piece has billet CNC end tanks, a large core, and integrated port injection via billet CNC snouts. This is the crown jewel of any 4.0TFSI and is every bit as functional as it is stunning.
The A2A keeps charge temperatures low during a pull, and the Port Injection integration allows use of ethanol concentrations up to E100.

SRM 4.0TFSI Exhaust Manifold with
Integrated Turbine Housing
Our Upgraded Exhaust manifolds with Integrated Turbine Housings alleviate cylinder 5 miss-fire issues due to excessive back-pressure often experienced by people running stock exhaust manifolds and allow the engine to exhale freely thereby alleviating the major bottleneck in the 4.0TFSI engine.
The upgraded exhaust manifolds are an integral part in the SRM1000 kit allowing the package to reach such high power output by flowing significantly more than the factory exhaust manifolds without sacrificing the extremely responsive spool that the 4.0TFSI is known for.
These same exhaust manifolds are proven on flagship and development vehicles and are the result of years of development.

4.0TFSI Manifolds with Turbine Housing
SRM 3" 4.0TFSI Intakes
The big brother of our SRM 4.0TFSI Intakes, the SRM 3" Intakes, are a requirement, allowing the Turbochargers to breathe well and are a significant upgrade over the stock intakes which are a known bottleneck on this platform due to their restrictive design. The inclusion of the A2A in this kit allows the larger intakes to fit.

SRM 4.0TFSI LPFP Upgrade
Essential to deliver enough fuel to the Factory Direct Injection and Port Injection System to achieve these power levels is the SRM 4.0TFSI LPFP Upgrade.
Proven dual LPFP solution that we have offered for years. These kits are extremely reliable and provide the heavy lifting for fueling the SRM1000 package.

DS1 Software Calibration
Before today the standard in the 4.0TFSI community has been piecing together parts that then require custom tuning which is a headache and has mixed results. Hardware variance and lack of access to a Dyno for most custom tunes provides limited and inconsistent results. Dealing with custom tuners can be time consuming and expensive. Tuning without a Dyno and a tuner present to monitor the vehicle can be dangerous and expensive. We have addressed these issues based on feedback from our Customers and the Community in the SRM1000 package by packaging the kit with a hardened calibration developed on our development vehicles on our in house Mustang Dyno. When you use the SRM1000 kit, the calibration is already done. The tune is hardened and ready to use out of the box.
It's as simple as it is powerful.
Flex Fuel Capability
Our Flex Fuel System, Port Injection System, and LPFP upgrade, when used with DS1, allow you to fill up any ethanol percentage from E0-E100. No more worrying about overstressing your fuel system with high ethanol concentrations. This kit addresses fuel flow completely, allowing you to just fill up with Flex Fuel and enjoy your car. Simply fill up with any concentration of Ethanol, and the Calibration in conjunction with the hardware will account for your ethanol concentration seamlessly, adjusting power output accordingly to a given concentration of Ethanol.
