Pipercross Panel Air Filter for BMW 7 Series E65/E66 730d 3.0

Upgrade the breathing of your BMW 7 Series diesel with a British built performance foam filter element designed to slot straight into the factory air box. This drop-in sports filter suits E65 and E66 730d 218 PS models produced 09/2002 to 04/2005 and delivers freer intake flow, crisp throttle response and long service life with simple cleaning and reuse.

We run these on our own cars and customer builds and the feedback is consistently excellent. Expect a smoother, more responsive drive from reduced restriction and robust filtration that protects your engine every mile.

• Flow-bench proven improvements that support stronger torque delivery and potential MPG gains
• Extended service intervals compared with cotton gauze alternatives
• No pleated V grooves to clog which makes cleaning quick and effective
• Lifetime road-use warranty for peace of mind
• Hand finished in Northamptonshire, United Kingdom

How the foam works for you

The performance comes from a multi-layer polyurethane foam element with a coarse outer layer, a medium middle layer and a fine inner layer. This progressive design traps contaminants through the depth of the material rather than on the surface. The result is consistently strong airflow as the filter loads with particles, helping your 3.0 diesel breathe freely and respond cleanly day after day.

Real world gains you can feel

• Quicker turbo spool and sharper pedal response
• Smoother acceleration across the rev range
• Reusable design cuts waste and long-term servicing costs

Fitment and installation

This is a simple drop-in upgrade for the standard air box. Most owners can swap the element during a routine service in minutes with basic tools. Prefer professional fitting or an induction health check
