The F-connector is located on the air intake boot and provides a connection point for the vacuum lines that run to the brake booster and fuel pressure regulator. The factory connector is made of plastic and with heat and exposure to the elements the connector becomes brittle and potentially cracks. As a result, a vacuum leak occurs which can cause poor idling issues, evap fault codes, and poor performance. 

This aluminum version from ECS Tuning is impervious to these issues, and will easy outlast the rest of your plastic and rubber vacuum system components. 

This item fits the following BMWs: 
E39 525i 530i 

E46 325i 325xi 330i 330xi

Z3 2.5i 3.0i

High flow filter replacement to get your engine breathing better than new!

Replace your dirty, restrictive, factory air filter with the ECS Tuning Exact-Fit High Flow Dry Air Filter!

Proper air intake flow will help your engine breathe better, improving power through the power band and improving fuel economy.

Higher flow than stock paper filters, this reusable filter will show an increase in performance immediately. An easy performance modification that is a direct replacement for your OEM filter.

Oiled versus Dry Filters:

Although both options will keep the air to your engine clean and improve airflow, there are a few differences to consider when choosing the best filter for you. Oiled filters do allow slightly better airflow than dry filters, however they require more maintenance. Oiled filters will likely get dirty faster, needing to be cleaned more regularly. When cleaning an oiled filter, it is necessary to oil them with filter oil afterwards. This filter will save you money by no longer needing to replace a paper filter.

Dry filters offer slightly lower airflow but are easier to maintain while still out performing the OE paper filter. Dry filters can be washed with warm soapy water. There is no oiling necessary afterwards.

Both dry and oiled filters flow better than stock and can be reused.

Key Features:

Direct replacement for the OEM filter

Higher flow than OEM

Dry air filter

Reusable

Only needs cleaning every 50,000 miles under normal highway driving conditions

ECS Tuning Silicone Turbo Inlet Hose – MINI Cooper S/JCW N14 (R55-R59)

Upgrade your MINI Cooper N14 with our high-flow silicone turbo inlet hose, featuring increased internal volume for greater airflow, a smooth interior finish for an uninterrupted flow path, and more available air for your turbo to consume, resulting in enhanced performance and throttle response.

Unlike the factory plastic inlet hose, which degrades over time and was never engineered with performance in mind, the ECS Tuning replacement features a durable, 4-ply silicone construction with wire reinforcement to handle higher temperatures and boost levels. Reinforced sections help prevent flex and collapse under load, and a smooth internal profile with a counterbored outlet reduces turbulence for optimized airflow to the turbocharger.

ECS Tuning also addresses a known issue where the OEM hose can walk off the turbo inlet and ingest the included gasket, often leading to premature turbo failure. This upgraded design provides a much more secure fit and peace of mind for performance-minded MINI owners.

Product Features

Constructed from heavy-duty, 4-ply fiberglass-reinforced silicone

Designed to resist collapse, distortion, and degradation from heat, oil, and fuel exposure

Smooth interior walls and gradual taper ensure unimpeded, efficient airflow

Includes spacers/adapters to accommodate factory or common upgraded turbo sizes

Gloss black finish adds a clean, high-performance appearance to the engine bay

Stainless steel smooth-band hose clamps are included for secure installation

Engineered to handle continuous operating temperatures up to 250°F

Direct replacement for the OE turbo inlet hose—no tuning required

Kit Includes

(1) Silicone turbo inlet hose
(2) Silicone turbo inlet rings for size adaptation
(3) Smooth-band stainless steel hose clamps
Engineering and Development
Designed, tested, and quality-inspected at ECS Tuning’s in-house R&D facility in Wadsworth, Ohio. Utilizing precision tools like FARO laser scanning, SolidWorks 3D CAD modeling, and in-house rapid prototyping, ECS ensures perfect fitment and long-term durability.

Installation Notes
Installation is simple and fully reversible. Remove the stock inlet hose and install the ECS silicone hose using the included clamps and spacers as needed. No permanent modifications required.

Not legal for sale or use in California on any pollution-controlled motor vehicle in accordance with the California Air Resources Board (CARB).

Free-flowing intake featuring a roaring induction noise and increased performance to replace your restrictive factory intake.

Upgrade your E46 driving experience by adding induction noise and increased air flow. Let your engine breath and listen to the sweet sweet intake sounds!

With the factory intake you are limited to a finite amount of air, this leaves your engine under-served and limits induction noise. When it comes to the recipe for upgrading your E46 there are a few ingredients that you must have, power and sound. While you can add an exhaust for a bit more power and sound, the biggest difference you can make is adding power and sound under your hood with a high-flow intake. The factory intake box is also referred to as a silencer specifically designed to lower the induction noise for a refined driving experience, this helped exponentially when selling the cars out of the show room circa early 2000's. We as enthusiasts are no longer interested in subdued intake noise and limited air-flow, we want pure induction noise, we want to hear the air being sucked into the engine as we push down on the accelerator.

Key benefits:

Flows on average 71 CFM more than the stock intake system, a ~27% increase in intake efficiency
Increased induction noise
Maintains factory air induction track
Maintains Stock MAF location, allowing user to switch back to the stock airbox and retain the ECS Silicone boot if desired
Design:

Durable, lightweight 6061 and 5052 aluminum intake tube and bracket design, finished in wrinkle black powder coat
Mounts to locations on chassis utilizing Stainless Steel M6 hardware
MAF mounts to intake using aluminum brackets sealed to intake system with OEM fitment
Maximizes available engine bay space to fit oiled ECS cotton gauze 7” filter
Silicone intake boot with improved flow characteristics replaces failure-prone facotry accordion intake boot with provisions for F-connector fitting and Idle Air Control (IAC) valve inlet

This ECS intercooler replaces the stock MINIature intercooler with a MASSIVE 250% larger surface area and a 125% thicker base core! This increase in core size improves flow while cooling compressed air into the intake manifold. Cast aluminum end tanks are TIG welded and feature machined transitions for maximum flow. This intercooler features a special black powder coating to prevent fin corrosion, as well as improve overall heat transfer to insure the lowest possible outlet temperatures.

FEATURES:

250% larger surface area compared to the OEM intercooler 125% thicker intercooler core TIG welded transitions Flat black powder-coated finish BENEFITS:

Drastically lower intercooler outlet temperatures/intake air temperatures Increased airflow Reduces the likelihood of heat soak DESIGN:

The limitations of the stock intercooler were apparent throughout our testing and design process. The stock part consistently struggled to manage charge air temperatures, even under normal driving conditions. Our ECS Intercooler has been designed to improve on every restrictive element of the stock cooler, enhancing cooling efficiency by lowering intake air temperatures even compared to the R56 Cooper S aluminum intercooler, allowing you to continuously push your car without the detriment of heat soak!

This ECS Front Mount Intercooler Kit was designed, engineered, tested, and quality inspected by our Research and Development team at our Wadsworth, Ohio facility. We strive for the highest level of precision and quality through leading-edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

NOTE: A performance tune is not required to run this intercooler. A tune will only increase the output of the engine when equipped with this intercooler.

**Some Prefacelift & GP2 models require slight modification inside the front bumper**
