Is software included with the APR B8 S4 throttle body?

Yes. The kit includes the APR Ultracharger ECU upgrade, which runs the larger throttle body and the supporting hardware. Software compatibility must be checked before purchase, so contact us with your vehicle details. Transmission software is also needed to reach the higher RPM limits.

How much bigger is the APR 3.0 TFSI throttle body?

The APR throttle body measures 80 mm, which APR rates as 28 percent larger than the factory unit. Together with the cast aluminum adapter and carbon fiber inlet tube, it removes a large restriction in front of the supercharger so air reaches it with less interruption.

How much power does the APR Ultracharger make on a B8 S4?

APR quotes up to 542 horsepower with its supercharger and crank pulleys and the rest of the required hardware, but does not name the test car. Treat that as a ceiling. The result depends on the full package, fuel, intake air temperature and software.

What comes in the APR Ultracharger throttle body kit?

The kit includes the 80 mm throttle body, a cast aluminum inlet adapter, a carbon fiber inlet tube, six new NGK spark plugs, new wiring, gaskets and hardware, and the APR Ultracharger ECU upgrade. The pulleys, exhaust and CPS cooler are sold separately.

Description

APR Ultracharger Throttle Body Upgrade for B8 Audi S4 and S5 3.0T

The APR Ultracharger Throttle Body Upgrade for B8 for the B8 and B8.5 Audi S4 and S5 replaces the factory throttle body on the supercharged 3.0 TFSI V6 with an 80 mm unit that is 28 percent larger, removing a major restriction in front of the supercharger. A cast aluminum adapter and a carbon fiber inlet tube carry air into it, and the kit includes the APR Ultracharger ECU upgrade that runs the larger throttle. It is the top hardware step for a B8 S4 or S5 that already has APR pulleys, a free flowing exhaust and the CPS cooler.

Required Supporting Hardware

The Ultracharger system only works as part of a complete package. APR requires a supercharger drive pulley, a supercharger crank pulley, an upgraded exhaust and the Supercharger Coolant Performance System, plus NGK BKR9EIX plugs gapped at 0.024 inch (plus or minus 0.002) and torqued to 30 Nm. Intake air temperature must stay below 75 C, the factory intake snow screen should be removed and the intake upgraded, and transmission software is needed to reach higher RPM limits.

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.
