<h3>About APR Performance</h3><p><strong>APR</strong> — short for Audi Performance &amp; Racing — has been at the forefront of European automotive performance since <a href="/1354-apr-tuned">its founding in 1997</a>. Established in Opelika, Alabama by automotive engineers Brett Augsburger and Stephen Hooks, the company set out to offer serious aftermarket upgrades for Volkswagen Auto Group vehicles. Their debut product, an ECU software upgrade for the 1997 Audi A4 1.8T, immediately signaled APR&apos;s commitment to precision engineering over gimmickry — and the brand has never looked back.</p><p>Today, <a href="/1354-apr-tuned">APR</a> is widely recognized as the global leader in performance aftermarket products for the VAG (Volkswagen Audi Group) platform. Their catalog spans an enormous breadth of hardware and software, covering vehicles from Audi, Volkswagen, Porsche, Bentley, Lamborghini, SEAT, Škoda, and more. Operating from a cutting-edge 80,000 square-foot facility in Alabama, APR develops everything in-house — from intake systems and turbocharger kits to suspension components, brake systems, and proprietary ECU/TCU calibration software.</p><h3>Engineering Philosophy</h3><p>What separates APR from the crowd is the depth of their engineering investment. Rather than simply sourcing off-the-shelf parts, APR develops and manufactures their own hardware, software, and data-logging tools. Their ECU software tunes — offered in Stage 1, Stage 2, and Stage 3 configurations — are regarded industry-wide for delivering exceptional power gains without sacrificing reliability. The same philosophy carries across every product line: every component is designed to meet or exceed OEM tolerances while pushing performance further.</p><p>APR&apos;s engine hardware lineup includes intake systems, intercoolers, turbocharger systems, ignition components, and <a href="/1354-apr-engine-oil-catch-can-56781">engine oil catch cans</a> — all engineered specifically for the turbocharged platforms found across VW, Audi, and Porsche model lines. Keeping crankcase vapors out of your intake tract is critical for maintaining consistent power and protecting engine internals, and APR&apos;s catch can solutions are purpose-built for VAG engines.</p><p>Transmission health gets equal attention. APR&apos;s transmission hardware includes short-shifters, shifter brackets, and fuel and transmission catch cans engineered to reduce drivetrain slack and protect gearbox components from oil contamination — a common concern on high-performance direct-shift and DSG transmissions.</p><h3>Exhaust, Wheels, and Beyond</h3><p>APR&apos;s exhaust systems are crafted from premium T304 stainless steel with mandrel-bent tubing for optimal flow. Whether you&apos;re after a more aggressive exhaust note or simply want a cleaner look at the rear bumper, APR&apos;s exhaust tail pipe tips are a popular finishing touch that pair function with European-inspired aesthetics.</p><p>On the wheel side, APR offers both flow-formed and forged alloy constructions. Their wheels are designed with motorsport principles in mind — reducing unsprung weight while delivering the OEM-plus fitment that Volkswagen Group vehicles demand. Available in multiple finishes and fitments, they are a natural complement to any suspension or brake upgrade.</p><p>Whether you&apos;re building a weekend track car, tuning a daily driver GTI, or extracting every last horsepower from an RS-badged Audi, APR offers a complete ecosystem of upgrades backed by decades of VAG-focused engineering expertise.</p>

Product Details

The APR CI100038-B is a high-performance rear carbon fiber turbocharger inlet tube designed specifically for 2.5 TFSI EVO engines. This upgraded inlet system replaces the restrictive factory tubing with a massive 4-inch carbon fiber tube, dramatically improving airflow to the turbocharger for increased power and enhanced throttle response.

Key Features:

  • Massive 4-inch diameter carbon fiber construction for maximum airflow
  • Significant flow gains over restrictive factory inlet tubing
  • Increases horsepower and torque across the powerband
  • Enhanced engine sound with improved turbo acoustics
  • Improved throttle response and turbo spool characteristics
  • Designed to work seamlessly with APR Turbo Inlet Pipe
  • Compatible with factory intake system or APR intake filter
  • Lightweight carbon fiber construction reduces weight

This is the rear carbon tube component only, designed for use with the APR front turbo inlet pipe. The large-diameter carbon fiber construction eliminates the restriction found in the factory inlet system, allowing your turbocharger to breathe freely and deliver maximum performance. Whether you're running a stock tune or an upgraded APR calibration, this inlet system provides the airflow capacity your engine needs to make power.
