Pipercross Plus Foam Panel Air Filter for BMW 3 Series 335i (E90 E91 E92 E93, N54/N55) – High-Flow Reusable Drop-In Intake Filter, Sports/Induction Air Cleaner Upgrade for OEM/Stock Airbox – Washable Performance Panel Element – CAI Alternative

Pipercross Plus Foam Panel Element for BMW 335i

Give your 335i the airflow it deserves with a premium drop-in sports filter that works with the original air box. Pipercross Plus replaces the factory paper element with a high-flow foam insert engineered for strong breathing, consistent performance and long-lasting durability. If you are hunting for a BMW 335i induction upgrade, performance air cleaner, panel element or drop-in intake filter, this is the one we recommend and use.

Built to flow, built to last

The Plus range swaps the usual mesh for a rigid 1 mm steel frame, improving stability without choking the intake. That stronger frame increases the effective flow area by 22.1 percent compared with the regular mesh design, helping your 3 Series 335i pull air cleanly even when moving hundreds of CFM through the performance foam media.

• Direct replacement element for the standard 335i air box
• High-flow performance foam for excellent breathing
• Upgraded 1 mm steel frame for strength and shape retention
• 22.1 percent gain in effective flow area versus the regular mesh
• Simple drop-in fit with basic tools
• No ECU tune or remap required

Proven on our cars and by our customers

We run this Pipercross Plus element ourselves and supply it to 335i owners who want a no-compromise intake refresh without deleting the stock air box. Feedback has been consistently positive on fit, finish and confidence in the reinforced frame and increased flow area. It is a straightforward, high value induction upgrade for the BMW 335i.
