Revitalize your classic E30 with improved throttle response, optimized airflow, and a clean, performance-oriented engine bay.

Designed specifically for BMW E30 models equipped with the M20 6-cylinder engine, this Turner Motorsport Intake System is a comprehensive upgrade that blends performance gains with OEM-style fitment and high-quality materials.

Passionately engineered to support increased engine efficiency across the RPM range, this intake system improves throttle response and ensures reliable airflow while maintaining full compatibility with factory components, including the stock AFM elbow.

Constructed with a durable stainless steel AFM bracket, 5052 powder-coated aluminum heatshield, and a heat-resistant silicone intake hose, this kit is built to last. It also includes a coolant overflow pass-through to support late-model E30 cooling systems, making it fully compatible with both early and late 6-cylinder models.

Installation is straightforward with no permanent modifications required, and detailed instructions are included.

Give your E30 the performance and clean aesthetic it deserves. Engineered by enthusiasts, for enthusiasts.

Complete your 24V swap with an intake designed specifically for the job. The Turner 24V Swap Heat-Shield Intake is engineered for E30 engine conversions, delivering cold, dense airflow in tight engine bays while retaining use of the factory air duct.

Most swaps leave you with two less-than-ideal choices: bolt a filter directly to the MAF and suck in hot under-hood air, or cobble together a universal intake that still lacks proper heat shielding. Our swap intake eliminates those compromises.

Our low-profile, heat-shielded design isolates the filter from radiant engine heat, works seamlessly with the stock 3.0" MAF, and supports factory CCV/ICV routing. The result is OEM-like fitment with modern airflow efficiency, no wiring hacks, no vacuum headaches, just a clean, reliable intake solution built for your swap.

Key features:

Heat shield designed to fit M20 and M5X swapped cars — mounts to the frame rail and ties into the ABS mount for rock-solid positioning. Creates a colder air pocket where the factory inlet duct is.
5052 powder-coated aluminum heatshield, stiff, corrosion-resistant, and finished for a long life in the swap environment.
The black silicone intake elbow and coupler is a compliant, high-temperature silicone that grips clamps and resists blow-off during repeated fitment and heat cycles.
Retains stock 3.0" MAF, no adapters needed to run the factory OBD1/OBD2 MAF in a factory-like location.
Designed to preserve stock CCV and ICV hoses for M50/M52 setups, this keeps the typical manifold and crank-vents intact, thereby avoiding vacuum and idle headaches common in swaps.
Stainless-steel hardware for longevity and corrosion resistance.
Fitment & compatibility:

Specifically engineered to work with common 24V conversions where space is tight and retaining OEM-style plumbing is desired. Mounts to factory frame rail/ABS brackets, minimal modification required.

M50/M52 engines are among the most popular 24V choices thanks to robust iron blocks, widespread availability, and strong aftermarket support, making them an excellent pairing for turbo or naturally aspirated builds. Keeping the stock MAF and CCV/ICV routing reduces the troubleshooting surface during install and helps complete your swap faster.
