Cold air intake systems represent one of the most beneficial types
of performance modification parts available for vehicles today.
These components work on the principle that cold air contains more
oxygen, and more oxygen equates to more power. Since vehicle’s
stock intake plumbing pulls in hot engine bay air, systems like the
aFe Super Stock Induction System bring in cooler, outside air and
increase available power.

Here is a list of notable factors why should consider getting an
aFe Super Stock Induction System for BMW vehicles:

Features
• Retains factory air box
• Replaces stock OE air filter
• Replaces factory intake tube
• Washable/reusable air filter
• Black textured molded tube
• Red polyurethane couplers
