{"product_id":"m50-intake-manifold-adapter-kit","title":"M50 Intake Manifold Adapter Kit","description":"The SLG M50 Intake Manifold Adapter Kit facilitates the swap of the high-flowing BMW M50 intake manifold onto M52TU and M54 engines, offering significant performance improvements. This conversion is known to yield approximately a 20 HP increase in naturally aspirated applications, enhance high-RPM airflow, sharpen throttle response, and create more engine bay space. The kit also eliminates the DISA valve, a common failure point that primarily benefits low-speed driving.\n\nConstructed from billet aluminum and manufactured in the USA, this adapter kit ensures durability and quality. The base kit includes a CNC-machined billet adapter plate, a CCV oil drain hose plug, fuel rail adapter plates to retain the factory fuel rail, and ICV port blocking plugs with hardware. The adapter plate is designed to accommodate both M52TU cable-driven throttle bodies and M54B25\/M54B30 electronic throttle bodies.\n\nOptional add-ons are available to enhance the installation and performance. These include a Silicone Hose Kit, made from motorsports-grade materials, available in 3\" or 3.5\" sizes to accommodate different M54 variants (3L M54B30 requires the 3.5\" hose). A Billet ICV Fitting is also offered as a more durable replacement for the factory plastic fitting. For those using aftermarket injectors, an Injector Spacer Kit can prevent leaks, and Port Matching Templates are available to help maximize performance by precisely matching head ports to the manifold.\n\nWhile the kit will function with a stock ECU tune, it is recommended to seek professional tuning for optimal performance, to eliminate check-engine lights, and to unlock maximum power. The product page also notes that while the kit generally fits M52TU and M54 engines, specific hose sizes for the Silicone Hose Kit depend on the M54 variant, with the 3L M54B30 requiring a 3.5\" hose, and a user reported that a different intake boot may be needed for a 3.0L M54 with a 3.5\" MAF.","brand":"SLG","offers":[{"title":"Default Title","offer_id":52866311881016,"sku":"SLG-M50-ADAPTER","price":140.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687672983.jpg?v=1787906706","url":"https:\/\/store.motormia.co\/products\/m50-intake-manifold-adapter-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
