Whether you just bought an Audi B8/B8.5 A4 or an earlier generation, the Audi A4 remains one of the most popular Audi models to modify. Since its debut in 1994, the A4 quickly became an Audi favorite and one of ours as well. What makes the A4 even better is its ability to transform into a beast on the road. With simple modifications, your A4 can become everything it was built to be and more. Check out our beginner’s guide to Audi A4 mods below to find out everything you need to transform your A4.
ECU Tuning by IE
We’ve said it before and we’ll say it again. ECU tuning is the fastest and easiest way to increase performance, horsepower, torque gains, and more. All you need is a Windows 7 or newer, the IE POWERlink Flash Tool, and our online software to unleash your engine’s full potential. Developed in-house, IE engineers are equipped with industry-leading tuning technology to completely reverse engineer the factory mapping and safely modify your A4 to maximize performance. Years of professional tuning high-powered race vehicles and intimate knowledge of Audi engines have resulted in a wicked fast A4 on both the street or the track. In fact, an IE stage 1 tune could yield up to 59 BHP over Audi’s current stock capabilities.
The IE Intercooler Kit
When pushed to higher levels of power the factory intercooler on an Audi A4 cannot properly dissipate heat from the engine. If this happens then your engine won’t be able to push out power properly. This is called “heat soak.” The IE FDS front-mount intercooler kit eliminates the heat soak and also increases your engine’s horsepower and reliability. In contrast to other intercoolers on the market which rely on natural airflow across the core, our FDS technology uses precisely shaped and placed fins cast into the intake plenum to fully take advantage of the large core volume effectively using the entire core. As a result, the IE FDS intercooler has been proven to reduce intake air temperatures more so than other units available, thus offering the largest power gains possible. Get the most out of your tuned or big-turbo Audi A4 by installing the IE FDS intercooler system.
Cold Air Intake
If you’re looking to increase performance look no further than an upgraded air intake. Not only does a specially made air intake increase throttle response, but it adds horsepower, torque, and a more aggressive sound. An air intake is able to do this by delivering colder air to your Audi A4. Our brand-new Audi A4 (2009-2015) Cold Air Air Intake delivers optimal performance upgrades through a high-flow velocity stake, custom heat shield, perfect fitment, stealth coolant line, and more. See how much additional power you can gain by switching out your factory air intake to a professionally-designed one.
IE’s A4 B8 Downpipe
Equipping your B8 A4 with an IE catted downpipe delivers additional horsepower, torque, and responsiveness. The Audi A4 exhaust leaves much to be desired. Free up airflow for better performance with our A4 Catted Downpipe. By switching out your current exhaust for a downpipe you’ll gain substantial power and torque capabilities, reduce emissions and unwanted smells, and allow significant engine movement without failing or cracking. These significant power gains are added through the entire RPM band by allowing the turbocharger to flow freely through the 3" downpipe, high-flow catalytic converter, and mid-pipe.
Wheels and Tires
Perhaps the most popular mod on the market is adding new wheels to your Audi A4. Widely-sought after by car enthusiasts, wheels and tires are a personalized feature that adds performance and aesthetic appeal. What makes this mod even better is its added improvement to the overall driving experience. Lightweight wheels, paired with performance tires, can increase overall balance, handling, and acceleration from added traction.
