BMW 1 Series 118d Diesel 2004-2007 Panel Air Filter by Pipercross (E81/E82/E87/E88) – High Flow Performance Intake Filter Element – Washable Reusable Foam, Drop-In OEM Airbox Direct-Fit Replacement – Lifetime Serviceable – UK Made

High-flow foam intake filter element for BMW 1 Series 118d 2004 to 2007

Give your BMW 118d a simple, effective breathing upgrade with this Pipercross high-flow foam element. It slips straight into the original air box with no cutting or extra parts required, delivering smoother intake airflow, crisper pedal response and long-term engine protection. Reusable and serviceable, it is a smart, eco-friendly alternative to throwaway paper filters and an ideal first performance mod for daily drivers and enthusiasts.

What makes it a great upgrade

• Drop-in fit for the OE air box for quick installation with standard tools
• Engineered to move significantly more air than a disposable paper element for improved drivability
• Triple-layer foam media captures dust and grit while maintaining strong flow
• Clean and refit design helps reduce running costs over the life of the car
• Consistent performance without the clogging you get from paper pleats
• Hand built in Britain by Pipercross in Northamptonshire
• Road-use lifetime warranty from the manufacturer

How the technology works

Pipercross uses a multi-density foam stack to filter progressively. A coarse outer layer stops larger particles first, a middle layer handles the bulk of contaminants and a fine inner layer takes care of the small stuff. The result is excellent filtration efficiency with outstanding airflow, helping your diesel breathe freely for sharper acceleration and a more eager feel across the rev range.

Real-world gains you can feel

Owners report keener throttle response, smoother pull and a subtle improvement in induction tone. We run Pipercross on our own cars and our customers consistently feed back that the reusable design offers brilliant value and confidence-inspiring engine protection mile after mile.
