Does the Eventuri 991 GT3 RS intake fit my car?

The Eventuri 991 GT3 RS intake fits the 991.1 and 991.2 Porsche 911 GT3 RS only, both with the 4.0L naturally aspirated flat-six. It does not fit the base 991 GT3 or other 911 variants. It is a direct bolt-on that uses the factory mounting locations, so no modification is required on a GT3 RS.

How much power does the Eventuri 991 GT3 RS intake add?

Eventuri lists a gain of 8 to 11 horsepower and 8 to 10 lb-ft on the 991 GT3 RS. On the flow bench the system moved 1025 CFM against 905 CFM for the stock airbox. Alongside the numbers, owners get sharper throttle response and a more pronounced induction character from the flat-six.

What makes the double Venturi housing special?

The Eventuri 991 GT3 RS intake uses a patented double Venturi filter housing that lets air pass through the filters with much less turbulence and drag than the OEM airbox. Combined with the increased internal volume and smooth carbon surfaces, it raises flow capacity while keeping intake air temperatures stable during repeated high-RPM use.

Is it a sealed intake, and does it heat soak?

The Eventuri 991 GT3 RS intake is fully sealed. The sealed carbon construction isolates the filters from engine bay heat to minimize heat soak, so intake air temperatures stay stable even under sustained hard driving. This is a key advantage over open-filter intakes on a track-focused car like the GT3 RS.

Which replacement filters does it use?

The Eventuri 991 GT3 RS intake runs two bespoke high-flow dry filters, each with a 192mm outer diameter and over 110,000mm² of surface area. Replacements are Eventuri part EVE-W192-FTR, the Type D2 filter, and two are required per service. Being dry filters, they can be cleaned and reused.

Is the Eventuri 991 GT3 RS intake returnable?

No. The Eventuri 991 GT3 RS intake is not eligible for return once opened, so confirm you have a 991.1 or 991.2 GT3 RS before ordering. Eventuri provides warranty coverage and damage-in-transit support, and the system is designed and hand-assembled in the UK.

Description

Eventuri Black Carbon Intake System for 991.1 / 991.2 Porsche 911 GT3 RS

The Eventuri 991 GT3 RS intake is a fully sealed prepreg carbon fiber intake system built to raise airflow, expand flow capacity, and hold intake air temperatures down on the naturally aspirated 4.0L flat-six of the 991.1 and 991.2 Porsche 911 GT3 RS. Developed through extensive flow-bench testing and real-world validation, it replaces the factory airbox with a larger-volume sealed carbon assembly for a smoother, less restrictive path to the engine. At its core is Eventuri’s patented double Venturi filter housing, which lets air transition through the filters with far less turbulence and drag than the OEM intake, so the system reaches a higher overall flow capacity while keeping temperatures stable through repeated high-RPM runs. Bespoke high-flow dry filters, carbon inlet ducts, an internally stepped silicone coupler, and a smooth internal carbon surface promote laminar flow to the throttle body, for a measurable power increase and a sharper induction character with OEM-level fitment.

About Eventuri

Eventuri was founded by a team of engineers and enthusiasts with backgrounds in aeronautics and tuning, all sharing a passion for cars and performance. After owning various aftermarket intakes over the years and being disappointed with gains that seldom lived up to their claims, they decided to take things into their own hands and set a new benchmark in intake design and technology. The goal was to engineer systems that provide real, measurable gains and to publish genuine figures to back them up. Their systems are developed using cutting-edge design, testing, and prototyping methods. Each design undergoes CFD analysis and is validated at the prototype stage through volumetric airflow measurement, intake temperature testing, and extensive dynamometer testing. Eventuri publishes all development data to illustrate the full process from concept to finished product. Only the best materials are selected for every component, down to the choice of fasteners, to ensure the quality of the final product is second to none.

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.
