Brand new from our dedicated Audi team and skilled engineers is our in-house designed Audi B8 3.0T Performance Supercharger Cooling System. Reduce your intake air temperatures and resist heat soak that robs your supercharged engine of power with our new Luft-Technik kit to get the most out of your supercharged V6.

The B8.5 S4/A4 S-Line Facelift has a sedate appearance not quite reflective of the performance under the skin of this executive sedan package. We�re here to help you change that with our new Gloss Black Front Lip designed in-house by our enthusiast team for a perfect visual upgrade to completely change the attitude of your Audi from meek and mild to aggressive and motorsport-inspired.

One of the most popular initial modifications made by enthusiasts is fitting a less restrictive and more effective intake system to their car. For your VW or Audi, the best places to start are the Carbon Fiber ECS Kohlefaser and Luft-Technik Induction Systems. Designed and engineered in-house for impeccable fitment, quality, and aesthetic appeal, these intakes are more than just extra HP; they are a stylish addition to both the driving experience and the visual appearance of your engine bay. Making your VW or Audi more fun and more powerful is easier than you think with ECS.

The most recognizable feature of the latest generation VW/Audi engines is the updated coil pack design. The new arrangement has been proven on supercars like the R8 and RS7, as well as the hyper-luxurious S8, and now your Audi can enjoy this same aesthetic effect. The more modern, reliable coil packs are also conveniently offered as a set of four.

Crafted to fit your B8 3.0T using all stock mounting locations, the all new Audi B8 Luft-Technik Intake sets a new benchmark in appearance, affordability, and durability - all while resisting the performance-robbing effects of engine heat soak. ECS has subjected this system to rigorous real-world testing, including power/efficiency measurements on our in-house chassis dynamometer. The convergence of perfected fitment, industry-standard quality, low-cost, and evidence-based performance claims has resulted in a gorgeous power-enhancer beyond anything available for your 3.0T!

The ECS Tuning Street Coilover System provides a sport-tuned, adjustable suspension with substantial performance benefits using high quality materials and coatings to replace your worn suspension, all while giving your vehicle that perfect ride height! Our ECS Coilover System provides confidence and precise control with a ride that is firm, yet compliant for the majority of enthusiasts.

The naturally aspirated 4.2L V8 in your Audi B6/B7 S4 delivers effortless revs and classic Quattro power, but once you start adding performance bolt-ons, aggressive tunes, or spiriting driving into the mix, the factory clutch rapidly becomes the weak link. The ECS Tuning Stage 2 Performance Organic Clutch Kit is engineered specifically for enthusiasts who demand high torque holding capability without suffering through the heavy pedal effort, chatter, or harsh engagement of race-style puck clutches. Designed to pair seamlessly with your existing factory dual-mass flywheel or an aftermarket replacement, this kit delivers a massive jump in torque capacity while keeping your daily commute smooth and civil. At the heart of this kit is our high-friction, steel-backed organic disc paired with a heavy-duty precision pressure plate. Together, they increase clamping force to handle up to 445 lb-ft of torque�giving you plenty of headroom for aggressive launch control, track days, and spirited backroad runs.

The ECS Tuning Inverted coilovers mount the larger damper body at the knuckle and the smaller shaft at the top, which significantly increases rigidity and reduces flex under cornering and braking loads. This improves steering precision, camber stability, and damping consistency, especially in high-grip or track conditions. The design also better protects the piston shaft from debris and contamination, making it more durable for harsh environments Our ECS Coilover System provides confidence and precise control with a ride that is firm, yet compliant for the majority of enthusiasts.

Engineered specifically for the B8 A4 and S4, our Form-Fit Trunk Sound Deadening Kit is designed to reduce the transmission of road noise, chassis vibrations, and irritating exhaust drone. Increase comfort, eliminate road noise, and enjoy a more comfortable ride! Pre-cut and precisely labeled, each multi-piece section of this sound deadening kit is tailored to the contours of the B8 S4 trunk, including the floor and spare tire well. Installation couldn't be more simple: peel and stick-no cutting, no trimming, and no guesswork required. The included 4mm thick sound deadening material includes exact cutouts for all trunk obstructions-wiring, mounting studs, clips, and more-ensuring a true factory-level installation. Tested across four independent conditions, our Form-Fit Trunk Sound Deadening Kit achieved an overall noise reduction of 5 to 14 decibels, a significant drop you can hear and feel!

Upgrade your stopping power with a Front & Rear Performance Brake Service Kit from ECS Tuning. When adding more horsepower to your vehicle, it is imperative that you have a way to slow that power down and bring it your vehicle to a stop. One way to do that is to upgrade your brake rotors and lines. Your factory brakes getting near the end of their service life? This is a great opportunity to replace and upgrade at the same time! ECS Tuning has assembled this kit to upgrade the braking on your vehicle using our own ECS 2-Piece Full Floating Cross-Drilled & Slotted Wave Rotors mated with the great EBC Yellow Stuff Brake Pads, a combination that will offer a dramatic upgrade to your stopping power. A great way to add performance braking power to your daily driver or track car.

Our engineers are constantly pushing the boundaries, developing innovative R&D solutions to problems often overlooked by the factory. From addressing minor annoyances to engineering fixes that can prevent catastrophic failures, our team dives deep to create effective upgrades. Many of these solutions involve replacing less durable plastic components with robust metal alternatives, ensuring lasting performance and peace of mind.

Like many Audi models, manual transmission-equipped B6/7 S4's came from the factory with dual-mass flywheels. While this design delivers excellent comfort, smooth gear changes, and minimal vibration, it also adds significant weight, tipping the scales at a hefty 26.5 lbs. For performance-oriented enthusiasts, the dual-mass flywheel is a hindrance, dulling engine response and overall driving engagement. With this flaw in mind, we set out to design a lightweight, performance-minded single-mass flywheel for B6/7 S4 enthusiasts! Our precision-engineered upgrade weighs in at only 18.9 lbs, a substantial weight reduction of 29%! This reduction translates to a dramatic improvement in throttle response and engine pep, allowing you to extract even more driving pleasure from your S4.

APR performance products for the Audi B9 S4 are engineered to unlock the full potential of the turbocharged 3.0T V6 engine while preserving the reliability, refinement, and everyday drivability expected from Audi's sport sedan platform. The product lineup includes ECU and TCU tuning, high-flow intake systems, intercoolers, exhaust upgrades, suspension components, and supporting performance hardware, all designed for precise fitment and seamless integration. Through extensive engineering and testing, APR upgrades deliver increased horsepower and torque, improved throttle response, optimized power delivery, and enhanced driving dynamics, allowing B9 S4 owners to experience a more exciting and capable vehicle on both the street and the track.
