K&N 57i-1001 (57I1001) Induction Kit / Cold Air Intake for BMW E36 3 Series 323i 325i 328i 323Ti (1991-1999) – Performance Air Filter System, High-Flow Reusable Cone/Pod Filter, M50/M52 2.5/2.8 Bolt-On Upgrade

K&N 57i Intake System - Part No. 57I-1001

Unlock crisp response and a richer induction sound on your BMW E36 straight-six with the K&N 57I-1001 intake kit. This free-flow setup replaces the restrictive OE air box, allowing the engine to breathe with less resistance for more urgent pick up and a smoother pull through the rev range. We have installed this kit on multiple customer cars and the feedback is consistently excellent - quicker pedal response, cleaner mid-range and an addictive intake growl.

Why choose this intake

• High-flow cone element for improved engine breathing
• Washable, reusable cotton gauze filter media - built to be serviced, not binned
• Vehicle-specific hardware and fittings for a straightforward bolt-on upgrade
• Enhances induction tone without the drone - ideal for spirited road use and track days
• Direct OE airbox replacement - no cutting of bodywork required
