aFe Performance Air Filters

aFe Performance Air Filters
Advanced Flow Engineering (aFe) makes these high performance, high flow OE air filters which replace the restrictive factory paper filter and lets your engine breathe better. These are stock replacement filters that drop in to your BMW's factory airbox system, and will increase flow to the engine, yielding more horsepower and torque.

Paper filters do a good job in keeping dirt out but can clogged easily so that it needs to be replaced frequently. aFe's performance filters are made with a washable/reusable cotton gauze which allows more airflow. aFe's filters feature a pliable progressive polyurethane seal, the deepest pleats in the industry, minimal wicking, and are factory pre-oiled with non-surfactant containing refined oil. Made in California, USA

Eurosport Cold-Air Intake Kits

Eurosport Cold-Air Intake Kits

Pick up 10-20 extra horsepower by replacing your restrictive stock airbox with a Eurosport Cold Air Intake! The finest Cold Air Intake Kit that we have seen, hands-down! This kit eclipses all others with its superior engineering, materials, fitment, and of course, performance. Starting at $389.95 it’s a little more expensive than some other kits but worth every penny. This intake is not just a simple heat shield with a cone filter – every aspect of the design has been analyzed to improve on the concept of a Cold Air Intake. As the purpose of a Cold Air Intake is to draw in cooler, denser air by blocking hot air from the engine, this kit’s engineering starts with the materials.

Heat Shield – While other intake kits use sheetmetal or aluminum to shield the filter from hot air, the Eurosport kit is designed with a composite material that is very resistant to heat. The shield is made from e-glassfiber, and has a heat transfer coefficient 100 times lower than aluminum! Why use metal to block heat? The composite shield is also very light and stiff. The entire intake kit weighs less than 6lbs, including the filter – compared to close to 20lbs for some other intake kits!

Intake Tube – For the same reasons as on the heat shield, the intake tube between the filter and the air flow sensor is made from carbon fiber. The carbon fiber is strong, light weight, and is compression molded for an exact fit and excellent air flow. It also looks cool (pun intended).

Air Filter – No compromises were made designing this intake. While a well-known American brand would have been more recognizeable to consumers, the ITG foam air filter proved superior during dyno testing. It’s also washable and serviceable meaning a long life and exceptional dust retention. ITG may not be as famous in America as other brands, but it’s one of the most popular filters in Europe and Asia. ITG Filters can be found in Championship-winning Touring Cars, Japanese SuperGT winners, ALMS, Grand-Am, and even Formula 1. ITG Air Filters come pre-oiled for immediate installation.

Eurosport Intakes come with all necessary hardware, detailed instructions. When installed, the shield provides a tight seal in the engine bay for the filter to draw cool air. The black finish with carbon fiber, and excellent craftsmanship, provides a “factory appearance”, showing off in a subtle way. We offer Eurosport Intakes for the BMW E36 3-series, E46 3-series, E39 5-series, and the Z3.

Air Mass Sensors and HFMs

Air Mass Sensors and HFMs
We sell OEM air mass sensors, air flow meters, and HFMs (Hot Film Meter) for many BMWs. When the mass air sensor is bad you will notice your engine running out of tune. Your fuel mileage will suffer, throttle response will be poor, and you will notice a lack of power.

There should be a Check Engine Light to alert you that the air sensor is having problems. However, there may not be a fault code for the air meter itself. Often times the code comes up as fuel trim or lean condition. In these cases the air sensor could be just one of a number of potential problems.

We only sell air sensors from Original Equipment Manufacturers like, Bosch, VDO, and Siemens. Please note that HFMs are an electrical part and cannot be returned for refund.

Samco Intake Boot

E36 6 Cyl Samco Silicone Intake Boot (325/328/M3) (more info)

If you are about to (or already have) eliminated the restrictive stock BMW ASC+T traction control system, you'll want to upgrade to this Samco silicone intake boot. Lose the factory "accordian" desgin boot, which creates lots of intake turbulence (read: lost power!). The Samco intake elbow has a perfectly smooth interior finish, with no sharp angles or other obstacles for intake air to get slowed by. It's made using 4 layers of high quality silicone, designed to last for many years in even the most extreme conditions.

Installing this boot assumes your car either does not have traction control (ASC), or you will be removing it from your car. (You'll also need to install a 10ohm / 1watt resistor accross the ASC actuator wiring, to simulate the presence of the ASC modules, and avoid causing ABS faults). Removing ASC is a great way to decrease intake restriction, and this intake boot is perfect for this upgrade. We offer an intake boot plug if you are deleting ACS.

This intake boot works very well with all cold air intake kits, including the Conforti cold air kit (with standard 3.0" HFM) and AFE intake kits. Have you already upgraded to the 3.5" Euro/540i HFM? No problem! We have a Samco intake bellows for that application as well (see part# SAMCO-BFHOSE1-BLK).

This Samco silicone intake boot fits the following BMWs:
1992-1995 E36 3 Series 325i, 325is & 325ic
1996-1999 E36 3 Series 328i, 328is & 328ic (with ASC delete)
1995-1999 E36 M3 3.0 & 3.2 (with ASC delete)
1997-1999 Z3 Roadster/Coupe 2.3 & 2.8 liter
1998-2000 MZ3 M Roadster/Coupe (S52 engine)

Part #: SAMCO-AFHOSE1-BLK

Price: $89.95 (USD)

E36 6 Cyl Samco Silicone Intake Boot (for upgraded 3.5 inch HFM) (more info)

If you've upgraded to the 3.5" Euro, 540i or Porsche HFM you know how much of a difference reducing intake restriction makes on these engines. This Samco silicone intake boot is the perfect mate for cars that have been upgraded with the 3.5" HFM, as it doesn't require any reducers or adapters (which impair air flow). Unlike the factory rubber intake boot, which has an accordian-like shape that causes turbulence, this boot has a smooth interior surface for best possible air flow. When coupled with the 3.5" HFM this makes for the best possible flow to the throttle body and intake manifold.

This intake boot assumes your car either is not equipped with traction control system (ASC) or it has been (or will be) deleted. We offer an intake boot plug if you are deleting ACS.

This Samco silicone intake boot fits the following BMWs:
1995-1999 E36 M3 with 3.5" HFM & ASC delete
1998-2000 MZ3 M Roadster/Coupe with 3.5" HFM & ASC delete

Part #: SAMCO-BFHOSE1-BLK

E46 M3 Samco Silicone Intake Boot (more info)

If you've already replaced the factory airbox of your E46 M3 for a cold air intake kit, the stock rubber intake elbow (which connects the mass air sensor / HFM to the intake manifold) is now your enemy. The stock S54 part has accordian-like grooves on both the inlet and outlet side, which slows down air flow. It's no wonder you don't see this type of restrictive setup on the E46 M3 CSL!

The Samco silicone intake boot for E46 M3 has a perfectly smooth interior surface, engineered for the best flow and smoothest transision -- no sharp edges or angles to hang up or slow down the air. Made in the UK using a 4 layer silicone design. Unlike the stock E46 M3 rubber boot, which is prone to drying, cracking and leaking, the Samco boot is virtually indestructable and ready for the rigors of heat temperature and extreme conditions.

This Samco silicone intake boot fits the following BMWs:
2001-2006 E46 M3 coupe & convertible

Part #: SAMCO-TB2754-BLK

Price: $129.95 (USD)
