Does the APR PEX Intake System for B9 RS5 need a tune?

No. APR states that the PEX Intake System for B9 RS5 requires no tuning. The published gain of 19 horsepower and 17 lb-ft at the wheels was measured on its Stage 1 (93 octane) RS5, where the additional airflow is used most effectively by the calibration.

How does the APR PEX intake compare with the carbon version?

Both replace everything from the inlet scoop to the turbo inlet, and APR measured the same 19 horsepower and 17 lb-ft gain from each. The PEX system uses a PEX airbox and composite inlet to reach a much lower price, while the carbon version adds the look of carbon fiber.

How much more air does the APR RS5 intake flow?

APR measured the factory system at 484 CFM at 28 inches of water and its own system at 658 CFM under the same conditions, a 36 percent increase. The lower pressure drop lets the turbochargers spool sooner and work in a more efficient part of their range.

Is the APR RS5 PEX intake filter washable?

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

Can the APR RS5 intake be used if I upgrade the turbos?

Yes. A billet turbo inlet adapter joins the system to the turbocharger, and a larger adapter can be fitted later to suit bigger turbos with a simple swap. The rest of the intake stays in place through the upgrade. No new filter is needed.

Description

APR PEX Intake System for B9 Audi RS5

APR’s PEX Intake System for B9 Audi RS5 delivers the full scoop-to-turbo-inlet design of APR’s carbon intake for the 2.9 TFSI V6 at a far lower price, using a PEX airbox and a thin-walled, heat-resistant composite turbo inlet. On the flow bench the factory system tops out at 484 CFM at 28 inches of water; the APR system flows 658 CFM under the same conditions, a 36 percent gain. On APR’s Stage 1 (93 octane) RS5 it added 19 horsepower and 17 lb-ft at the wheels. It is the value choice for an RS5 owner who wants the performance and can live without carbon fiber.

Design and Performance

Space around the twin-turbo V6 is tight, so APR used heat-resistant composite for the turbo inlet to keep its walls thin and its bore as large as physically possible. The PEX airbox shields the filter from engine bay heat, with cutouts that draw cooler air from low-temperature zones and give the engine a refined, sportier tone. A billet adapter at the turbo inlet can be swapped later for larger turbochargers.

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.
