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 on our APR Stage 1 (93) equipped S4.Additionally, the APR Full Intake System is engineered with functionality, performance, and sound in mind.\u003c\/p\u003e\n\u003cp\u003eThe PEX airbox shields the filter from the engine bay, while its thoughtfully placed cutouts 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.Testing Results That Speak for ThemselvesThe performance of the factory intake system is no match for the APR Full Intake System.\u003c\/p\u003e\n\u003cp\u003eThe stock setup is limited to a maximum flow of 400 CFM at 28” H2O, whereas our full intake system achieves a significant 31% improvement, flowing 525 CFM under the same conditions.This increase in airflow is paired with a dramatic reduction in pressure drop across the system, allowing the turbocharger to spool faster and operate in a more efficient range of its compressor map.\u003c\/p\u003e\n\u003cp\u003eThe result is not just theoretical—it’s power you can feel.On our Stage 1 (93) tuned Audi S4, simply installing the APR Full Intake System delivered an additional +19 AWHP and +20 AWFT-LBS of torque, proving its capability to unlock your vehicle’s full potential.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"APR","offers":[{"title":"PEX","offer_id":43079266041936,"sku":"APRCI100072","price":520.95,"currency_code":"USD","in_stock":false},{"title":"Carbon Fiber","offer_id":43079266074704,"sku":"APRCI100043","price":1303.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0058\/0252\/4785\/files\/153a5b0294f35b234e2562ea8482402741fd3fcb.jpg?v=1793210927","url":"https:\/\/shop.redline360.com\/products\/apr-intake-system-for-audi-s4-s5-3-0t-2018-2025-pex-airbox-ci100072","provider":"Redline360","version":"1.0","type":"link"}
