Does the APR Carbon Fiber Intake for B9 S4 and S5 need a tune?

No. APR states that the Carbon Fiber Intake for B9 S4 and S5 runs without any new tuning, so it can go onto a car on factory software or on an existing APR calibration. The published power gain was measured with APR Stage 1 software on 93 octane, which is where the intake shows its full benefit.

How much power does the APR intake add to a B9 S4?

APR measured gains of 19 wheel horsepower and 20 lb-ft of wheel torque when the intake was added to a car already running APR Stage 1 software on 93 octane fuel. Those gains come from 31 percent more airflow and a lower pressure drop at the turbocharger inlet.

Why does the APR intake replace the turbo inlet pipe as well as the airbox?

APR found that the narrow factory turbo inlet pipe is the main restriction on the 3.0 TFSI, so a new airbox alone changes little. Its one-piece carbon fiber pipe stays as large as possible from the 4 inch filter outlet to the turbo, which cuts the pressure drop that limits a filter-only upgrade.

Can the filter be cleaned and reused?

Yes. The 7 x 7 inch filter uses washable pleated cotton gauze, so it can be cleaned and reused for an extended life or replaced easily. Its large surface area, with a 5.5 inch frontal inlet and a 4 inch outlet, keeps it breathing freely for many miles.

Will the intake still fit after a turbocharger upgrade?

Yes. APR mounts the inlet pipe to the turbo through a billet adapter ring, and a larger adapter can be installed later to suit a bigger turbocharger inlet. The rest of the system stays, so owners planning a turbo upgrade do not need to buy a second intake.

Description

APR Carbon Fiber Intake for B9 Audi S4 and S5

APR’s Carbon Fiber Intake for B9 Audi S4 and S5 replaces the whole induction path of the 3.0 TFSI V6, from the inlet scoop to the turbocharger inlet. APR found the narrow factory turbo inlet pipe to be the real restriction on this engine, so its one-piece carbon pipe stays as large as possible from the filter to the turbo, and the finished system flows 31 percent more than stock. It is the right first hardware upgrade for a tuned B9 owner who wants measurable power and a richer induction note.

Design and Performance

Carbon fiber lets APR keep the tube walls thin, maximizing internal diameter while forming the organic shapes needed to clear a crowded engine bay. The airbox adds flow paths facing away from the engine to keep intake temperatures down, and the lower pressure drop at the turbo inlet helps the turbocharger spool faster.

Features

One-piece carbon fiber inlet pipe from the filter to the turbocharger
Airbox with additional flow paths facing away from the engine
Billet turbo inlet adapter that can be exchanged after a turbo upgrade
Deeper induction sound that stays civil

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
