Integrated Velocity Stack
IE’s built-in 5.5" velocity stack transforms airflow, creating a seamless transition to the engine for maximum power and efficiency. This smooth segue reduces drag and power-robbing turbulence at the critical point as air enters the supercharger.
Dual Air Zones
Fresh, cold air flows freely from multiple sources, with high and low-pressure zones working together to deliver uninterrupted airflow directly to your supercharger. Cool air is forced in through the front grille, while the open-bottom design pulls additional fresh air from behind the bumper. The intake is shielded to block radiant heat from the engine bay, ensuring only the coolest air enters the system for maximum performance.
Throttle Body Ready
Pair your intake with the IE 3.0T Throttle Body Kit for even more power. The IE 80mm Throttle Body Kit includes a larger inlet adapter making it a direct fit to the IE Polymer Intake System, further maximizing airflow. No extra parts or modifications are required.
IE Throttle Body Kit sold separately.
Dyno Results
Countless design revisions, rapid prototyping, flow bench testing, dyno runs, and real-world verification has resulted in a performance intake design with power gains of up to +21 WHP on tuned engines!
Performance data was collected during controlled testing on IE’s own in-house dyno facility. Multiple back to back runs were performed on a dual pulley stage 2 B8 S4 in exacting conditions; the only change made to the vehicle between runs is the swap from stock to the IE Polymer Air Intake System.
Flow Results
Flow testing confirms consistent airflow gains up to +73% CFM over the stock setup, allowing your engine to breathe freely at any power level. By increasing airflow and volume, IE’s intake design ensures smooth, unrestricted power delivery from ECU tunes and performance hardware upgrades.
The 5" air filter surface area and increased air volume improve efficiency.
The internal velocity stack provides a low-turbulence transition.
High & low-pressure zones channel low-temp airflow quickly to the engine while protecting it from radiant engine heat.
Install your new air intake with basic hand tools in only minutes. IE’s polymer intake is a direct factory upgrade with stock-style mounts for a perfect, hassle-free installation.
- Average install time around 20-30 minutes
Precision Design
Please your inner perfectionist. 3D scanning tools are leveraged to create a high-resolution digital environment allowing IE’s engineers to take advantage of all available space for a complete performance design while ensuring a perfect alignment and fit. Even first-time installers will appreciate the straightforward, no guesswork design.

Delivery time depends on the product. Most in-stock parts ship within days, while carbon fiber and made-to-order items may require production time before they ship. For the specific timeline on any item, check the Availability & Shipping section on that product’s own page — the guide below covers our general shipping types.
Shipping Overview
Depending on the item, free air freight may be available for select carbon fiber components, with estimated shipping around 1–2 weeks after dispatch. Larger hoods, oversized body components, and certain made-to-order items may require sea freight and longer delivery windows. If timing is important, please contact us at support@eurospeed.co before placing your order.
Shipping Coverage
EuroSpeed ships to customers across the United States and internationally. Shipping is included in the price of eligible products for your convenience and covers the initial cost of delivery to your destination.
Import duties, taxes, clearance fees, or customs charges required by your destination country are not included and remain the recipient’s responsibility.
Order Processing & Fulfillment
Every order is reviewed, processed, and prepared before shipment. Most in-stock products are processed within 1–3 business days, though some orders may take up to 5 business days depending on fulfillment location, product type, order volume, or courier pickup timing.
EuroSpeed stocks select high-demand products at our U.S. facility and international fulfillment centers. Because our catalog includes many vehicle-specific and specialty parts, not every product is held in-house at all times.
Some orders may ship through our trusted fulfillment network, which may include verified manufacturing partners, authorized distributors, regional warehouses, and international fulfillment centers.
- Orders may ship from a U.S. warehouse, international warehouse, manufacturer, or authorized fulfillment partner.
- Some products may require additional handling, processing, production, or quality-check time before shipment.
- Orders enter fulfillment shortly after being placed and may no longer be eligible for cancellation once processing, production, or shipment preparation begins.
Custom, Made-To-Order & Oversized Items
Custom, made-to-order, and oversized product categories may include carbon fiber steering wheels, hoods, trunk lids, fenders, front lips, splitters, side skirts, diffusers, bumpers, body kits, widebody components, select spoilers, rear wings, and other large carbon fiber components.
Many carbon fiber items are made to order. Some products may already be stocked and ready to dispatch when available, but if inventory is unavailable, your purchase reserves the next available production slot instead of waiting for a separate restock listing.
Production time: Production can take 1–4 weeks depending on product type, selected options, finish, current queue, and quality-control timing.
Shipping time: Shipping can take 2–10 weeks depending on item size, freight method, destination, customs processing, carrier delays, warehouse transfers, and final delivery location. Carbon fiber steering wheels typically ship faster, with shipping usually taking 3–7 business days after dispatch.
By purchasing custom, made-to-order, or oversized items, you acknowledge and accept the extended production, fulfillment, and shipping timelines associated with these products.
Tracking Updates & Delays
All orders receive a tracking number once generated by the courier. Tracking may take 2–3 business days after dispatch to show movement in the courier’s system.
Certain international, oversized, or freight shipments may show limited updates during transfer between fulfillment locations, warehouses, customs, or final-mile carriers. In some cases, tracking is provided or begins updating once the item reaches a regional warehouse, local carrier, or final delivery network.
Shipping timelines are estimates and are not guaranteed. Delays caused by high order volume, weather conditions, customs inspections, carrier disruptions, production queues, warehouse transfers, holidays, or other external factors may occur and are outside of EuroSpeed’s direct control. These delays do not qualify for cancellations or refunds unless the carrier officially marks the package as lost.
Delivery Responsibility
Upon delivery, carefully inspect the item for visible defects or damage before signing for it. If the item is damaged or not as expected, do not accept the package. Once a damaged or defective product is accepted, EuroSpeed cannot cover return shipping costs.
