    THE QUALITY POLYMER INTAKE
    THE QUALITY POLYMER INTAKE

    Performance First

    The internal volume of the intake and its complex shapes are the results of application-specific engineering for the Audi B9 platform. Every inch has been performance designed to feed your turbocharger with the most airflow possible.

    Throttle Down, Sound On

    THROTTLE DOWN, SOUND ON

    The stock airbox on your Audi A4 or A5 2.0T has been manufactured to silence all engine and turbo sounds at any performance cost. Upgrading your air system with an IE polymer intake will release a symphony of engine throttle, spool, and blow-off sounds that will be music to your ears.

    THROTTLE DOWN, SOUND ON

    Multiple Pressure Zones

    This intake features high and low pressure zones to feed the turbocharger and engine demands for any power goal. The majority of fresh air supply is supplied to the filter from the grill. If additional air demands are required, the intake will pull low-pressure air through the filter cover as needed.

    Built-in Velocity Stack

    The integrated velocity stack smooths the airflow from the large filter into the charge system with excellent laminar properties. This powerful design detail results in a very high inertia flow with reduced drag and power-robbing turbulence at the critical point as air enters the turbocharger.

    Precision Design

    PRECISION DESIGN

    3D scanning tools are leveraged to create a high-resolution digital environment allowing our engineers to take advantage of all available space for a complete performance design while ensuring a hassle-free install.

    Power 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 10-20HP on tuned engines !

    Flow Bench Testing

    Back-to-back flow bench testing details consistent airflow gains of up to +70 CFM over stock! This increase shows efficiency over the factory parts and capability to provide increased airflow demands from ECU tunes and performance hardware upgrades.

    AVAILABILITY

    Please read before ordering. Eurosport Performance does not carry live inventory on this site. Most products are ordered for you directly from the manufacturer or our suppliers, and we follow their lead times. Placing an order confirms you have read and accepted the availability terms below.

    In stock
    Ships within 24 to 48 hours
    Products marked in stock are on our shelves in Montreal and leave within one to two business days.
    Ordered for you
    Most orders ship in 5 to 7 business days
    Everything else is ordered from the manufacturer or supplier when you order. Delays can occur; if they do, we contact you.
    Supplier lead times apply
    If a product is not listed as in stock here and is on backorder at the manufacturer, it will most likely be on backorder for us too. We will tell you as soon as we know.
    We keep you informed
    You receive a confirmation when the order is placed, a notice if a delay comes up, and tracking the moment it ships.
    Frequently asked questions
    Is this product in stock right now?

    Only products explicitly marked in stock are on our shelves. For everything else, the fastest way to know the current lead time is to ask us before you order; we check with the supplier and reply with a date.

    Why does my order say "confirmed" but has not shipped?

    Confirmed means we have placed the order with the manufacturer or supplier on your behalf. Shipping follows once the part reaches us or ships directly to you, usually within 5 to 7 business days for products that are available at the source.

    What happens if the part is on backorder?

    We tell you as soon as the supplier confirms it, with the expected date when they give one. You can keep the order open, switch to an alternative we suggest, or cancel for a full refund before the part ships.

    Can I cancel if it is taking too long?

    Yes. Any order that has not shipped can be cancelled by contacting us, and the refund goes back to your original payment method. Please contact us rather than opening a dispute with your bank: a cancellation takes us minutes, a chargeback takes weeks and freezes the refund in the meantime.

    Do you ship directly from the manufacturer?

    Sometimes. Larger or special-order items can ship to you directly from the supplier to save days in transit. You still receive tracking from us either way.

    Where do my parts ship from, and are there duties?

    Orders ship from Montreal or directly from our suppliers. For Canadian addresses the price you pay is the price, with no import or duty fees added on delivery. See our shipping policy for details.

    How will I know when it ships?

    You get an email with the tracking number the moment the label is created, and you can follow the order in your account on the site or in the SPECD app.

    Want a lead time before you order? Email us or use the contact page with the product name and your vehicle, and we will confirm availability with the supplier.

    WARRANTY

    Products are warrantied by their manufacturer. Eurosport Performance is an authorized reseller: every part we sell is covered by the manufacturer's own warranty, with its own terms and duration. Claims go through us, so you deal with Eurosport Performance rather than a form on the brand's site, but whether a claim is accepted is the manufacturer's decision.

    Manufacturer terms apply
    Duration and coverage are set by the brand and differ from one to the next: some cover one year, some a lifetime, some only the original purchaser. The brand's warranty page is the reference; ask us if you cannot find it.
    We file the claim for you
    Contact us with your order number, photos and a description of the issue. We open the claim with the manufacturer, follow it up, and arrange the repair, replacement or credit they approve. The manufacturer decides whether the claim is accepted.
    Fitment guarantee: North America only
    We guarantee fitment for vehicles sold in the North American market. Vehicles from other markets are out of scope; specifications differ, and it is the customer's responsibility to confirm compatibility before ordering.
    No warranty on tuning files
    ECU and TCU tunes and other software files are sold without warranty and are not returnable once delivered or flashed. Tuning can affect your vehicle's factory warranty; please read the brand's terms before purchasing.
    Proof of purchase
    Your Eurosport Performance order is the proof of purchase every manufacturer asks for. Keep the order confirmation; it is also in your account on the site and in the SPECD app.
    What is usually not covered
    Damage from improper installation, modification, abuse, racing or an incorrect application for the vehicle, and normal wear items such as pads, clutch discs and filters. Shipping and labour are covered only when the manufacturer's terms say so.
    Frequently asked questions
    How long is the warranty on this product?

    It is the manufacturer's warranty for that product. Where the brand publishes it, we note it in the description; otherwise contact us before ordering and we will confirm the exact terms with them.

    A part failed. What do I do?

    Stop using it if it is a safety-related part, then contact us with your order number, clear photos, and when and how the issue appeared. Do not return anything until we confirm the claim; manufacturers often require an inspection or an authorization number first.

    Who decides if my claim is accepted?

    The manufacturer. We prepare and submit the claim, provide the proof of purchase and push for a fair outcome, but acceptance, replacement or credit is their call under their terms. We pass their decision on to you as soon as we have it.

    How long does a claim take?

    It depends on the manufacturer. Simple cases are approved in days; claims that need the part inspected can take a few weeks. We keep you updated at each step and push when it drags.

    Is there a warranty on ECU or TCU tunes?

    No. Tuning files are software; once delivered or flashed they cannot be returned, and they carry no warranty from Eurosport Performance or, in most cases, from the tuner. Support for the tune itself (revisions, flashing questions) comes from the tuning brand under its own terms.

    My car is from outside North America. Is fitment guaranteed?

    No. Our fitment guarantee covers vehicles sold in the North American market only. European, Japanese and other market vehicles can differ in engines, electronics and dimensions, and a part listed for the North American model is not guaranteed to fit. If you order for one of these vehicles, confirming compatibility is your responsibility, and fitment issues on such vehicles are not covered by returns or warranty.

    Is installation covered?

    Labour is not covered unless the manufacturer's terms specifically include it. Having the part installed by a qualified shop protects your claim: improper installation is the most common reason a manufacturer declines.

    Is a warranty issue the same as a return?

    No. Returns cover unused parts you no longer want, under our refund policy. Warranty covers a part that fails in use, under the manufacturer's terms. If you are unsure which applies, contact us and we will point you to the right one; please do not open a bank dispute, as it pauses both processes.

    Questions about coverage before you buy? Email us with the product and your vehicle and we will confirm the manufacturer's terms.
