It is plug and play with no permanent modifications, no cutting, and no splicing. Just connect it and go. The MADNESS GOPedal Plus comes with its own app, so you can dial in throttle response to exactly how you like it.

Thousands sold. Thousands of positive reviews.
MADNESS MAXBoost Engine Module
What is the best engine module for an Alfa Romeo Giulia 2.0? The MADNESS MAXBoost, our newest-generation engine module.
MAXBoost is designed to deliver increased power and torque while keeping the Giulia smooth and enjoyable for everyday driving.
Installation is plug and play with no permanent modifications. Pair it with the GOPedal Plus and you can control both throttle response and engine performance from a clean, reversible setup.
MADNESS Sport & Sport Plus Lowering Springs
Do lowering springs improve handling on an Alfa Romeo Giulia 2.0? Yes. Dramatically.
We offer two versions for the Giulia 2.0 so you can choose the drop you want.
Sport is the milder option for owners who want a lower stance and sharper handling without going too low.
Sport Plus drops the car further and evens out the stance for a more planted, finished look.
Both are engineered and manufactured in Germany, designed specifically for the Giulia 2.0, and tuned to preserve everyday ride quality.
GFB Diverter Valve
Why replace the factory diverter valve on an Alfa Romeo Giulia 2.0? Because consistent boost control becomes increasingly important as engine performance increases.
The GFB diverter valve upgrades the factory system with a more robust performance-oriented design.
It is a direct-fit supporting modification that makes sense on both lightly modified vehicles and Giulias running additional engine performance upgrades.
MADNESS MAXFlow Carbon Fiber Intake
What is the best closed air intake for an Alfa Romeo Giulia 2.0? The MADNESS MAXFlow Carbon Fiber Intake System.
This is not an open-element intake. The system uses a genuine carbon fiber housing connected directly to the factory front air inlet so the engine can draw outside air through a high-flow intake system.
Inside the carbon housing is an Italian-made BMC Twin Air Conical Filter. It uses both lateral and central airflow, is washable and reusable, and is designed for long service life.
Designed specifically for the Giulia and Stelvio 2.0 Turbo platform. Direct bolt-on. Fully reversible.
Sprint Filter High Flow Air Filters
What is the best high-flow air filter if you want to keep the factory air box? Sprint Filter offers several excellent options for the Giulia 2.0.
This is a great route for owners who want improved airflow but prefer to retain the factory airbox.
Sprint Filter S High Performance
The everyday high-flow option. It replaces the factory paper filter with Sprint Filter performance polyester media while keeping the original airbox.
Sprint Filter F1 Ultimate Performance
The highest-flow version for owners who want to maximize airflow while retaining the factory intake layout.
Sprint Filter WP Ultra Fine Waterproof
Designed for owners who want high airflow combined with finer filtration and added protection in wet or dirty conditions.
MADNESS Autoworks Giulia 2.0 Performance Exhaust
What is the best performance exhaust for an Alfa Romeo Giulia 2.0? The MADNESS Autoworks Giulia 2.0 Performance Exhaust System.
We offer two configurations so you can match the sound to the way you drive.
Lusso is the more refined choice, with a tuned, throaty exhaust note that remains polished during daily driving.
Monza is the more aggressive option. It is more open and louder for owners who want the exhaust note to become a much larger part of the driving experience.
Both are complete cat-back replacements designed to improve exhaust flow and install as direct-fit systems.
SILA Concepts Blow Off Adapter Plate
Does a blow off adapter plate add power to an Alfa Romeo Giulia 2.0? No. The sound is why it stays such a popular mod.
The SILA Concepts Blow Off Adapter Plate adds the distinctive turbo whoosh when you lift off the throttle.
It is a simple direct bolt-on billet aluminum plate designed to work with the factory solenoid valve. Installation is reversible, making it an easy way to add more character to the Giulia.
Wheel Spacers
Do wheel spacers help an Alfa Romeo Giulia 2.0? Yes, when they are properly designed for the car.
Wheel spacers help fill the arches and create a wider, more planted stance.
MADNESS Autoworks carries Giulia-specific options from MADNESS, Athena, Corsa Forza Performance, and other manufacturers.
These are hub-centric, vehicle-specific solutions available in different widths and with the correct extended hardware.
Custom Wheels with High Performance Tires
Should you upgrade the wheels and tires on an Alfa Romeo Giulia 2.0? Yes, if you want the grip, stance, and appearance to match the rest of the build.
Custom wheels completely change the presence of the Giulia. Pair them with the right high-performance tires and you can also improve grip, steering response, and overall road feel.
MADNESS Autoworks carries numerous wheel sizes, designs, offsets, and finishes for the Giulia.
Carbon Fiber Dress Up
How do you finish an Alfa Romeo Giulia 2.0 build? Dress it up in carbon.
Once the performance and stance are right, carbon fiber is one of the best ways to finish the car.
MADNESS Autoworks carries a wide selection of Giulia carbon fiber parts, including mirror covers, spoilers, interior trim, steering wheel accents, exterior pieces, and more.
Done correctly, carbon fiber ties the entire build together and gives the Giulia a more purposeful performance look.
The MADNESS Approach: Power Without the Risk
Here is the thing about modifying a turbocharged car: it is easy to go too far.
Push every component to its limit and you can turn a fantastic daily performance sedan into a car that is less enjoyable to own. That is not what we are about.
The goal with these upgrades is to improve performance, handling, response, sound, and appearance while maintaining the balance and drivability that make the Giulia so good in the first place.
Many of these modifications are bolt-on, direct-fit, and reversible, allowing owners to build the car progressively rather than changing everything at once.
Depending on the exact combination of modifications, vehicle condition, fuel, and setup, owners can achieve meaningful gains in power and response while keeping the build focused on reliable street performance.
The Alfa Romeo Giulia 2.0 is already an excellent driver's car. The goal is not to change what makes it special — it is to make those qualities even better.
