Why fit the APR Intercooler for B9 S4 and S5?

APR found that the factory cooler on the 3.0 TFSI lets intake air temperature climb to high levels even on factory software. The APR Intercooler for B9 S4 and S5 more than doubles frontal area and adds about 58 percent more core volume to keep intake temperature down.

How much bigger is the APR S5 intercooler than stock?

The APR core measures 2.25 x 16.2 x 22 inches, with 356.4 square inches of frontal area and 801.9 cubic inches of volume. The factory cooler has 162.4 square inches of frontal area and 507.62 cubic inches of volume, so the APR core is far larger on both counts.

Do I need a tune for the APR B9 S4 intercooler?

No tune is required, and APR recommends the cooler at every stage. On factory software it holds intake temperature down. On a tuned S4 or S5, where boost and heat both rise, the larger core helps the engine keep the timing and power the calibration is asking for.

Does the APR S5 Sportback intercooler need cutting?

No. APR designed it as a plug and play install with no trimming or drilling. It replaces the factory front mount cooler on the B9 S4, S5 Coupe, S5 Cabriolet and S5 Sportback with the 3.0 TFSI V6, and APR supplies full installation instructions.

Which years of B9 S4 and S5 does the APR intercooler fit?

APR lists the B9 S4 from 2018 to 2025, the S5 Coupe and Cabriolet from 2018 to 2024, and the S5 Sportback from 2018 to 2025, all with the 3.0 TFSI V6. For the SQ5 with the same engine, APR sells a separate intercooler system.

Description

APR Intercooler for B9 S4 and S5 3.0 TFSI

The APR Intercooler for B9 S4 and S5 swaps the narrow factory cooler on the 3.0 TFSI V6 for a tall front mounted bar and plate core. Frontal area more than doubles, from 162.4 to 356.4 square inches, and core volume climbs from 507.62 to 801.9 cubic inches. APR found that the factory cooler lets intake air temperature climb to high levels even on factory software, which is why it recommends this upgrade at every stage of tune.

Core and End Tank Design

Testing set the core style, fin density and size: a bar and plate core with staggered, louvered fins that cools hard while keeping pressure drop low. Smooth cast 356 aluminum end tanks spread air evenly across the core, and every unit is pressure tested so no boost is lost to leaks.

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.
