BMW 335d / X3 / X5 EGR & Cooler Delete for 3.0 Diesel M57N2 Engines

Exhaust Gas Recirculation Blanking Kit with Cooler Bypass for BMW 3.0d M57N2

Unlock cleaner airflow and sharper response on your BMW 3.0 diesel with this premium billet aluminium EGR blanking and cooler bypass kit. Designed for the M57N2 engine found in 335d, X3 and X5 models, this race pipe solution tidies the bay, helps reduce inlet temps and combats soot build up in the intake tract and turbo. CNC machined in the UK, it uses the factory fixings for a neat, OEM style fitment while retaining the anti shudder valve for smooth shutdown.

We use this kit on our own builds and our customers love the results. It is a proven upgrade for anyone chasing reliability, cleaner intake paths and performance-ready airflow on BMW diesel tuning projects.

Why choose this billet race pipe and cooler bypass

• Machined from a single billet for strength and durability with no welds to fatigue
• Smoother intake charge path that helps lower inlet air temperatures for improved performance
• Helps prevent the inlet manifold and turbo from clogging with carbon deposits
• Retains the ASV so engine shutdown remains smooth and refined
• Discreet install profile that mirrors the OE valve housing for a clean, factory look
• Unique grub screw boost reference with a tiny orifice, so no separate inline reducer is required to stop gauge flutter
• Tidy finish thanks to the compact boost take off design that avoids bulky brass fittings
• Brushed aluminium finish, UK made
