Integrated Engineering Black Friday | Up to 40% Off at XPH
13th Nov 2026
The Integrated Engineering Black Friday Sale is live at Extreme Power House (XPH), with up to 40% off. If you’ve been planning an intake upgrade for your Golf GTI, looking for more cooling capacity for your Audi S4, or comparing tuning options for your Volkswagen or Audi, now is a good time to revisit your parts list.
Integrated Engineering, also known as IE, offers hardware and tuning tools for several generations of turbocharged Volkswagen and Audi vehicles. Start with what you want to change. An intake can bring out more turbo and induction sound. An intercooler helps manage charge-air temperature during repeated acceleration. The POWERlink tool lets you flash compatible IE software and log data.
Volkswagen MK7 GTI, Golf R, and Audi 8V A3/S3
For the earlier MQB platform, XPH lists the IE MK7/8V Air Intake System (IEINCI11) for compatible Gen 3 1.8T and 2.0T applications. The listing covers models including the MK7 GTI and Golf R and Audi 8V A3 and S3. The kit uses a five-inch air filter, aluminum intake piping, and a full-width heat shield. If you’re starting with an otherwise stock car and want to hear more of the turbo, this is a straightforward upgrade to compare.
If you’re also considering a turbo inlet, check what comes with the intake. The inlet connects the intake tract to the turbo, and IE lists it as an optional upgrade for this system. Comparing the parts together helps you plan what to install now and what to add later.
Volkswagen MK8 GTI, Golf R, and Audi S3
XPH lists an IE Air Intake System for the MK8 GTI (IEINDB4) with model options covering the Golf R and Audi S3. The system uses a full-width inlet scoop, a large filter, and a high-flow turbo inlet. Use the model selector on the product page to find the configuration for your vehicle. The GTI and Golf R have different factory turbo inlet dimensions, which matter when you choose the kit.
For cooling, compare the IE Black FDS Intercooler Kit (IETPCI1B-BK). XPH lists it for compatible MK7 and MK8 GTI and Golf R models and 8V and 8Y Audi A3 and S3 applications. It uses a bar-and-fin core and IE’s Flow Distribution System to cool compressed air on its way from the turbo to the engine. If your car feels different after several back-to-back pulls or on a hot day, charge-air temperature is one variable worth logging before you decide which upgrade to prioritize.
Audi B9 and B9.5 S4/S5 3.0T
For the Audi B9 and B9.5 S4 and S5 with the 3.0T V6, XPH lists the IE Polymer Air Intake System (IEINCK5). It’s a starting point if you want more audible turbo sound with the factory turbo. If you’re considering a hybrid turbo later, compare the intake with the optional IE cast turbo inlet and check what the turbo manufacturer calls for before buying the two together.
XPH also lists the IE FDS Intercooler (IETPCK1) for compatible Audi B9 S4, S5, A4, A5, and Allroad applications. The B9 catalog covers several engines and body styles, so check the model, engine, and year on the individual listing. If you drive a B9 or B9.5 Q5 2.0T, XPH lists a dedicated IE Polymer Intake (IEINCZ5) for that platform.
Audi 8V RS3 and 8S TT RS 2.5T
For the five-cylinder platform, XPH lists the IE Carbon Fiber Intake (IEINCQ1) for compatible Audi RS3 and TT RS 2.5T DAZA applications. It adds a visible carbon fiber finish under the hood and is an option if you want the turbo and induction sounds to come through more clearly. XPH also lists the IE Turbo Inlet Pipe (IEINCQ2) for the 8V RS3 and 8S TT RS. Check the chassis and engine code, especially if you’re shopping for a newer RS3.
IE POWERlink and Tuning Compatibility
The IE POWERlink Mobile V4 (IESOVU7) connects to a compatible Volkswagen or Audi through the OBD-II port. XPH sells the device separately from the ECU and TCU software. If you’re planning a flash, check software availability for your exact vehicle and transmission, then review the fuel grade and hardware requirements for the file you intend to run.
