Dinan 18-25 BMW M5/M8 (F90/F91/F92/F93) Turbo Inlet Pipes

From the factory, the plastic inlets are limited and allow very little volume to pass as they neck down dramatically to the turbochargers themselves. This reduction stifles flow and increases the pressure ratio pre-turbine causing the turbochargers to work harder than necessary. This is a problem Dinan engineers took great care in rectifying through exhaustive prototyping and testing to ensure maximum future power potential while also having compatibility with numerous potential configurations. The benefit of their hard work are Dinan Turbo Inlets that are constructed of gloss UV coated 2x2 carbon fiber and are designed to mate seamlessly with whatever level of modification to the intake system you anticipate (paired with either stock air boxes or the full Dinan Cold Air Intake System). Where the carbon fiber ends an aluminum adapter to connect to the stock turbocharger begins. Using the same factory locking system, installation in this area is straightforward and earmarked by a "click" when secure. The simplicity making this quite possibly the quickest and least aggravating installs on the platform you will encounter. The pipe itself has been created to offer the largest possible cross-sectional area all the way from the intake filter to the turbo, a staggering 200% increase in volume over stock. This is the key to maximum performance gains from the system and the reason for the organic and unorthodox shape of the Dinan inlet system. While the effects of the additional volume are pronounced on a vehicle equipped with the factory airboxes and results in average gains of +11 WHP / +13 WTQ from 2000 RPM to redline, the overall efficiency of the entire intake system is maximized when paired with the Dinan Cold Air Intake that is also delivering an increased volume of cooler air earlier in the intake tract. Carbon Fiber - F90/F91/F92/F93

• More Power: Max gains of 22 WHP and 18 lb-ft of torque @ 6500 RPM on an otherwise stock vehicle. Average gains of 11 WHP and 13 WTQ from 2000 RPM to redline.
• Compatible with both the OEM and Dinan intake systems. Compatibility with other intakes not guaranteed.
• More volume (~200% more than stock, 105 cubic inches vs. 35 cubic inches per side).
• Larger internal diameter throughout (maximum cross-sectional area allowed).
• Carbon fiber construction for heat insulation and visual appeal.
• Quick and easy bolt-on installation.
• Outflows the factory inlets.

Upgrade your BMW M5 or M8 with the Dinan Turbo Inlet Pipes, designed to significantly improve airflow and boost overall engine performance. Crafted from gloss UV-coated 2x2 carbon fiber, these inlet pipes provide superior heat insulation and a sleek visual appeal. They are engineered to replace the factory plastic inlets, which are limited in flow capacity and cause unnecessary pressure buildup before the turbochargers. By increasing the cross-sectional area by approximately 200%, these inlets allow for a much greater volume of air to pass through—up to 105 cubic inches per side compared to the stock 35 cubic inches—resulting in noticeable horsepower and torque gains. The larger internal diameter throughout the pipes ensures maximum flow efficiency, making this a key component for enthusiasts seeking to extract more power from their vehicles. Installation is straightforward with a quick bolt-on design that uses the factory locking system, providing a secure fit marked by a satisfying "click." This ease of installation means minimal downtime and frustration during setup, ideal for both seasoned tuners and casual enthusiasts. When paired with the Dinan Cold Air Intake System, these inlets optimize airflow and temperature management further, delivering an average of +11 wheel horsepower and +13 lb-ft of torque from 2,000 RPM to redline, with peak gains of up to 22 WHP and 18 lb-ft at 6,500 RPM. Compatible with both OEM and Dinan intake systems, these inlets are designed to enhance the existing setup without requiring extensive modifications. The use of high-quality carbon fiber not only provides durability and heat resistance but also adds a premium aesthetic touch to your engine bay. Engineered for performance and ease of installation, the Dinan Turbo Inlet Pipes are an essential upgrade for anyone looking to maximize the potential of their BMW M5 or M8 platform.
