Why upgrade to the APR Air to Water Intercooler for RS5?

The factory cooler is small for the 2.9 TFSI and heat soaks quickly, so the ECU pulls power during a quarter mile pass, a lap or a spirited drive. The APR Air to Water Intercooler for RS5 is 194 percent larger and holds intake temperature down so power stays consistent.

How much larger is the APR RS5 intercooler than stock?

The APR core measures 5,500 cubic centimeters, against 1,870 cubic centimeters for the factory unit, which makes it 194 percent larger. APR also states that it flows more than the factory cooler at every pressure differential it measured, so the extra capacity comes without a penalty in restriction.

Does the APR RS5 Sportback intercooler need a tune?

No. APR states that the system does not require tuning. It works on a car with factory software and adds consistency on a tuned car, where higher boost produces more heat and the factory cooler would otherwise cause the ECU to pull power sooner.

What comes with the APR B9 RS5 intercooler?

The kit includes the intercooler assembly, application specific coolant hoses, EZ-Flow silicone charge air hoses with T-bolt clamps, and CNC bent, laser cut brackets. APR supplies installation instructions and support, so no extra hoses or brackets need to be sourced for the listed RS5 models.

Does the APR RS5 intercooler fit the coupe and the Sportback?

Yes. APR lists the B9 RS5 Coupe from 2018 to 2024 and the RS5 Sportback from 2019 to 2025, both with the 2.9 TFSI twin turbo V6. It bolts on in place of the factory cooler, and APR supplies instructions and support for the install.

Description

APR Air to Water Intercooler for RS5 B9 2.9 TFSI

The APR Air to Water Intercooler for RS5 replaces the small factory cooler on the B9 RS5 and its 2.9 TFSI twin turbo V6. At 5,500 cubic centimeters the APR core is 194 percent larger than the 1,870 cubic centimeter factory unit. The stock cooler struggles to shed heat, and the ECU pulls power to protect the engine during a single quarter mile pass, a lap or a hard drive. The APR system keeps intake air temperature down so power stays consistent.

Construction

APR pairs its own aluminum cooling core with CFD optimized cast aluminum end tanks, then CNC machines and TIG welds the assembly. The system flows more than stock at every measured pressure differential, and it arrives with application specific coolant hoses, EZ-Flow charge air hoses and CNC bent, laser cut brackets.

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.
