What vehicles does the PRL High Volume Intake System for DE5 fit?

The Intake System for DE5 fits the 2024-present Acura Integra Type S (DE5) with the 2.0T turbo I4 K20C1 engine, including all variant models such as RHD and international models. It uses the factory turbocharger inlet pipe, so verify your setup before ordering.

Does the Intake System for DE5 require a tune or ECU calibration?

No. The PRL High Volume Intake System requires no ECU calibration. It matches the OEM MAF bore size and uses silicone components, so it installs on the DE5 without changes to the factory ECU calibration.

Is the PRL Intake System for DE5 CARB legal?

Yes. The PRL High Volume Intake System is 50 state CARB certified under CARB Executive Order D-878-8, so it is approved for use in California and other states that follow CARB standards.

How much more airflow does the Intake System for DE5 provide?

PRL reports a 133% increase in air volume versus the OEM intake. The system pairs a 6-inch cone filter with an HDPE rotomolded airbox that uses the factory air duct and seal, and adds a secondary duct. PRL's testing on the FK8 platform found a 10 to 20 horsepower loss with the hood closed, which the secondary duct is engineered to eliminate.

How does the Intake System for DE5 reduce heat soak and air starvation?

The HDPE rotomolded airbox uses the factory air duct and seal to maximize airflow while minimizing heat soak. The factory rubber inlet connects to the airbox and extends over the core support, channeling fresh air through a duct in front of the radiator support. The secondary duct then prevents air starvation during performance driving.

Description

PRL Motorsports High Volume Intake System for DE5 Acura Integra Type S

PRL’s High Volume Intake System for DE5 Acura Integra Type S represents the latest advancement in air intake technology for the platform. Drawing on experience gained from the FK8 High Volume Intake, PRL made significant improvements to the construction, materials, and overall design to produce a system that competes with the top options available. The result is a complete intake solution designed to improve power output, thermal management, and overall engine efficiency.

Development and Testing

Testing conducted on the FK8 platform identified a 10 to 20 horsepower loss with the hood closed, confirming that the factory duct presents a notable restriction under closed-hood conditions. To resolve this, PRL engineered a secondary duct for the Intake System for DE5 specifically to eliminate air starvation and maintain consistent airflow during performance driving.

Design and Performance

The DE5 High Volume Intake System features a 6-inch cone filter paired with an HDPE rotomolded airbox that utilizes the factory air duct and seal to maximize airflow while minimizing heat soak. The factory rubber inlet connects to the airbox and extends over the core support, channeling fresh air through a duct positioned in front of the radiator support.

About PRL Motorsports

PRL Motorsports started in 2007 as PRL Racing, a small group of enthusiasts outside Pittsburgh, Pennsylvania, united by a single goal: faster lap times. What began trackside quickly earned a reputation for engineering excellence, producing race cars capable of 9-second quarter-mile passes as early as 2007 and 6-second times by 2009. By 2011, the operation had grown into PRL Motorsports, expanding from trackside tuning into full-scale product development and fabrication across Honda, Nissan, Mitsubishi, and Subaru platforms. In 2018, PRL Motorsports made a deliberate shift to focus entirely on manufacturing, concentrating their resources on engineering and producing performance components rather than installation and tuning services. Today, PRL Motorsports operates from a 25,000 sq/ft facility in Export, Pennsylvania, staffed by over 25 professionals and equipped with CNC machining departments, automated cutting stations, dual-spindle lathes, 5-axis milling centers, and robotic loading systems running 24-hour production capacity. Their catalog covers intercooler systems, intake systems, turbocharger systems, exhaust components, and throttle body and intake manifold adapters, many of which carry CARB compliance and SEMA Garage certification. From a 9-second S13 to tuning the first 10th-generation Civic into the 10-second range in 2019, PRL Motorsports has built its reputation on one principle: never settle, always push for the best possible outcome.

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.
