aFe's MagnumFLOW Pro 5R air filter is a high flow oiled air intake filter. These are fully washable, allowing you to clean your air intake filter and immediately improve performance. The construction of the tall, deep pleats allows for ample dust and debris collection that allows for more time between intake cleanings. With the flange being polyurethane, we are confident that your aFe air filter will not leak, ensuring optimal performance.

• 5 layer fine mesh cotton gauze filter media
• Polyurethane base and top

Since 1999, aFe (Advanced FLOW Engineering) has been developing and manufacturing high quality accessories in their facility in Corona, California. Starting with air filters and intake systems, and now expanding into exhaust systems, suspension components, tuning modules, and more, aFe products are a great way to improve the performance of your BMW without altering its fundamental character. Owned by a BMW enthusiast, aFe power is recognized the world over as a leader in quality performance products for your BMW.

This is a drop-in stock replacement aFe performance air filter that installs into your BMW's factory airbox. This particular filter fits the following BMWs:

E31 8 series: 840i 840ci 1991-1999
E32 7 series: 740i 740il 1993-1994
E34 5 series : 530i 530i Wagon 540i 1993-1995
E34: M5 1991-1993
E39: M5 2000-2003
E53 X5 : X5 4.4i 4.6is 4.8is
Z8 : Z8

This version has an oil-free filter media for less maintenance. For the best flowing filter, with the best performance gain, we always recommend the standard aFe "Pro5R " filter (which has a blue pre-oiled filter media), but this oil-free filter flows only slightly less than the blue Pro5R style aFe filter, and requires no re-oiling after cleaning the filter.

Apex EC-7 18x8.5" Square Wheel Set

Apex 8.5" wheel set for the front and rear of your BMW. These are a bit wider than stock to put more rubber to the road. This helps to reduce understeer on cars with staggered wheel sets and gives you the option to rotate tires. If you're tracking your BMW you should absolutely have a square wheel set (the same size front and rear). Adding a wider wheel will get you more rubber where it counts - reducing understeer and improving initial turn-in. We have put this wheel set together using four APEX 8.5" wheels in a ET45 offset. A 8.5" wheel allows for 225-245 R-comp or performance tires.

APEX light alloy wheels are the next evolution in flow-forged wheel technology for BMWs. Flow-forming is a semi-forging process that produces a wheel typically stronger than a traditional cast wheel yet is still light weight. The wheels are around 10lbs lighter per wheel than a comparable factory wheel! That's reduced unsprung weight that improves all aspects of performance. The spokes and barrel have been designed to allow generous clearance for big brakes. In other words, these wheels are very impressively engineered and look great too! The design is based on classic motorsport themes that blend with BMW styling and appearance. These wheels look right at home on many BMW models. Multiple color and profile options allow you to set just the right look and stance for your car. As well as being pleasing to the eye these are very strong and functional wheels that are at home on the street as well as the racetrack. Don't let the price fool you - these wheels are high quality, high strength, and in high demand.

Note: careful consideration of wheel width, offset and tire sizing must be observed when choosing and installing larger wheels. Adding larger wheels may lead to rubbing on suspension components or bodywork. Wheel spacers, new alignment settings, inside fender modifications, or other adjustments may be required.
