APR PEX Intake System - 3.0T Audi S4 / S5 (B9)

The APR Full Intake System is perfect for Audi enthusiasts seeking the ultimate intake upgrade. Unlike others that address only a portion of the intake system, requiring the inlets and outlets to neck down to the factory diameter for compatibility, this comprehensive solution replaces every component from the inlet scoop to the turbocharger inlet. This eliminates restrictions throughout the system, ensuring unmatched airflow and turbo performance with the largest inlet physically possible.

Key to the system’s superior performance is its optimized design. Making the inlet as large as possible is the goal but space is extremely limited. By maximizing the internal diameter with thin-walled heat-resistant composite materials, APR achieves an impressive 31% more airflow compared to stock. This translates directly into improved turbocharger efficiency, faster spool times, and significant power gains, adding +19 AWHP and +20 AWFT-LBS of torque when paired with the APR Stage 1 (93) tune.

Additionally, the APR Full Intake System is engineered with functionality, performance, and sound in mind. The PEX airbox shields the filter from the engine bay, while its thoughtfully placed cut outs provide additional airflow and a refined engine sound. A massive 7” x 7” washable pleated cotton gauze filter further enhances performance with vast filtration surface area while ensuring long-lasting usability.

Whether you’re focused on unlocking power, enhancing turbo performance, or future-proofing your vehicle for upgrades, the APR Full Intake System is the only intake you’ll ever need.

Features:

  • Complete System Replacement: Includes inlet scoop, airbox, filter, and turbo inlet pipe, eliminating all factory restrictions.
  • +19 AWHP & +20 AWFT-LBS Power Gains: When paired with APR Stage 1 (93).
  • 31% More Airflow: Improved from 400 CFM (stock) to 525 CFM.
  • Enhanced Turbocharger Efficiency: Reduces pressure drop, allowing the turbo to spool faster and operate more efficiently.
  • High-Temperature Composite Turbo Inlet: Enables thin-wall tubing for maximum internal diameter and airflow.
  • PEX Airbox: Heat-shield design with additional flow paths in low temperature zones.
  • Massive Washable Filter: 7” x 7” pleated cotton gauze with a 5.5” frontal inlet and 4” outlet for superior filtration and performance.
  • Future-Proof Design: Billet turbo inlet adapter accommodates larger turbos with a simple swap.
  • All-Inclusive Kit: Includes OEM gaskets, clamps, and hardware for an easy, bolt-on installation.
  • Emissions-Friendly: Requires no tuning and is compliant with emissions standards.
  • Improved Engine Sound: Adds a sporty, refined tone without being overbearing.

Exactly what they say it is.
Size: 72"W x 72"L (Pack of 1), Color: 1b. Clear-heavy
Appears to work exactly as advertised, and quality is very satisfactory, which is always a pleasant surprise on Amazon. Magnets are strong enough, plastic feels pliable and durable. Don't forget the rings aren't included.

Good shower liner
Size: 72"W x 72"L (Pack of 1), Color: 1a. Clear
Actually works! No soap scum or mildew. I have had this shower curtain up since December and all I do is rinse it off. No soap scum. Good item. Good value.

Too lightweight and flimsy, but it does the job
Size: 72"W x 72"L (Pack of 1), Color: 1a. Clear
This shower liner works as expected, but it is a bit lightweight, and will drift around in the shower. I will look at getting a more heavy duty one in the future. This one has the 3 magnets, and that isn't enough. I would recommend getting one with double the magnets and a thicker plastic. I went cheap and regret it slightly, but at least these things are made to be disposable. Other than that, the durability seems good, and it looks and feels like you would expect, but as stated, the plastic is flimsy and flutters around. Seems fairly mold resistant vs other liners I've used from the store (like cheaper Walmart ones etc).
