Product Description
The SB 2178 air filter is a large-area panel filter designed to provide the enormous air volume required by V8 engines with displacements from 4.0 to 5.0 liters. It ensures the smooth operation of the Valvetronic and Double VANOS systems, which are extremely sensitive to the quality of the air mixture.

Specifications:
Type: Panel (rectangular).

Material: Synthetic fiber with a special impregnation, resistant to high temperatures and humidity.

Design: Deep pleating with additional pleat retention prevents deformation even under peak intake loads.

Applicability:

BMW 5 Series (E60/E61):

540i (4.0L N62)

545i (4.4L N62)

550i (4.8L/5.0L N62)

BMW 6 Series (E63/E64): 645Ci, 650i (2003–2010).

BMW 7 Series (E65/E66): 735i, 740i, 745i, 750i (2001–2008).

Key Benefits:
High Flow Rate: Minimal airflow resistance allows the V8 engine to fully unleash its power potential.

Precision Component Protection: Effectively retains microparticles, preventing them from reaching MAF sensors and cylinder bores.

Perfect seal: The elastic polyurethane edging retains its properties throughout its entire service life, eliminating the suction of unfiltered air.
