ITG Profilter Performance Air Filter - BMW M5 E28 3.5 S38B35 (1985-1987) - High-Flow Reusable Tri-Foam OEM Replacement Panel Filter

ITG Profilter Sports Panel Insert for BMW E28 M5 S38 3.5

Give your classic E28 M5 a proper breathing upgrade with the ITG Profilter drop-in panel element. Built around ITG’s racing heritage and engineered for real-world road use, this serviceable foam intake filter delivers superb airflow with excellent particle capture, helping your legendary S38 straight-six breathe more freely while staying protected.

Key advantages

• Triple-layer reticulated foam for outstanding dirt retention without the usual restriction
• Free-flowing design for crisper throttle response and smoother revs
• Low restriction maintained even as dust builds up, ideal for spirited driving
• Washable and reusable for long-term value compared with disposable paper elements
• Race-bred materials and construction refined for road and track-day use
• Direct-fit, drop-in panel insert that works with the standard air box

What you will notice

Expect a more eager intake feel, cleaner mid-range pull and a subtle induction tone as the S38 breathes with less effort. We run ITG foam elements on our own cars and feedback from our customers mirrors our experience — excellent fit, top-tier filtration and consistent performance over many miles.

How the foam technology helps your engine

ITG’s multi-stage foam pairs with a specific oil to trap fine contaminants throughout the depth of the media, not just on the surface. This depth-loading design keeps airflow stable for longer compared with a typical paper insert that clogs quickly, supporting reliable power and safeguarding your valves, rings and bores.
