"This product is of the highest quality, and the ease of installation makes the investment even more worth it. I recommend this intake to everyone. I shaved at least 1sec. off 0 to 60 in a stock 525i just by adding the cold air intake. The more air you can get in, the more air you can get out! Thanks, Darrell" —Darrell K from Athens, TX bought an aFe Cold Air Intakes for a 2005 BMW 5-Series, 525i, 2.5L 6-cyl. engine.
