Performance Foam Intake Panel for BMW 7 Series E65 E66 730d 2004–2005

Unlock smoother, freer breathing for your 3.0 diesel straight six with this British-built Pipercross performance foam element. It is a drop-in upgrade for the factory air box on the BMW 7 Series E65 and E66 730d, giving a cleaner, less restrictive path for air while maintaining excellent engine protection. Reusable and washable, it is a smart long-term upgrade that helps your diesel breathe easier and respond better.

Why this intake element is a smart upgrade

• Direct drop-in for the standard air box. No cutting or modification required
• High-flow, progressive-density foam media supports stronger induction and crisp throttle response
• Superior dust holding capacity compared with paper, helping sustain airflow for longer between services
• Reusable and washable with the correct cleaning kit, reducing waste and service costs over the life of the car
• Robust construction for daily use on UK roads, with a lifetime warranty for road applications
• Subtle enhancement to intake tone under load while remaining refined at cruise
• Made in Britain by Pipercross for dependable quality and fit

How the foam media works

The multi-layer, open-cell foam uses a progressive structure that captures larger particles on the outer face and finer contaminants deeper within the material. This design balances filtration and flow, helping your turbo-diesel maintain consistent performance without the rapid restriction often seen with paper elements.

Compatibility

• BMW 7 Series E65 and E66 730d 3.0 diesel, 231 bhp
• Model years 2004 and 2005
• Fits the original equipment air box as a like-for-like insert
