Dinan Carbon Fiber Turbo Inlet Pipes – BMW M5 (F90) / M8 (F91/F92/F93)

OVERVIEW

The Dinan Turbo Inlets are an easy-to-install bolt-on upgrade that removes the single largest obstacle in the factory intake system: the turbocharger inlets themselves. From the factory the plastic inlets neck down dramatically at the turbochargers, stifling flow and raising the pre-turbine pressure ratio so the turbos work harder than they need to.

Dinan’s replacements are built from gloss UV-coated 2×2 carbon fiber with an aluminum adapter where the carbon meets the stock turbocharger, and they use the factory locking system — installation is announced by an audible click when the connection is secure. The organic, unorthodox shape exists to deliver the largest possible cross-sectional area from filter to turbo: roughly 200% more volume than stock, 105 cubic inches per side versus 35. On a car with the factory airboxes that is worth average gains of 11 WHP and 13 WTQ from 2000 RPM to redline, and the whole intake tract works better still when paired with the Dinan Cold Air Intake.

Instrumented engine testing showed benefits beyond the dyno figures. The inlets let the turbocharger run at a lower pressure ratio and therefore more efficiently, which translates to lower pre-turbine backpressure, lower turbo shaft speeds, lower compressor discharge temperatures and headroom for higher boost pressure.

SPECS

• More power: maximum 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
• Approximately 200% more volume than stock — 105 cubic inches versus 35 cubic inches per side
• Larger internal diameter throughout, at the maximum cross-sectional area the chassis allows
• Gloss UV-coated 2×2 carbon fiber construction with aluminum turbocharger adapters
• Retains the factory locking system at the turbocharger for a bolt-on fit
• Compatible with the stock airboxes or the full Dinan Cold Air Intake system
• Dinan published installation labor: 1.0 hour
• Emissions: Dinan states “This product is NOT LEGAL FOR SALE OR USE IN THE STATE OF CALIFORNIA. Testing with the California Air Resources Board, in order to achieve 50-state compliance, is pending with CARB.”
• Outside California, Dinan states the part is legal under the EPA Tampering Policy dated November 23, 2020
• Dinan warranty: on a vehicle still covered by the BMW new-car limited warranty (4 years/50,000 miles), Dinan products are warranted for the remaining term of that warranty; otherwise Dinan Performance Products carry a 2-year, unlimited-mileage warranty from the date of original purchase. Wear and maintenance items — friction materials, filters, fluids, spark plugs, drive belts and bulbs — are excluded.

PARTS INCLUDED

• Left and right carbon fiber turbo inlet pipes with their aluminum turbocharger adapters, as supplied by Dinan.
• Complete kit as supplied by Dinan; see the installation instructions for the full bill of materials.

TECH RESOURCES

Additional Parts Required

• None. Dinan specifies no additional hardware for this part — the inlets bolt to the factory airboxes and lock into the stock turbocharger fittings.
• Optional pairing: the Dinan Cold Air Intake (D760-0049). Dinan states the efficiency of the whole intake system is maximized when the inlets are run with its cold air intake.
• Installer-supplied tools: standard hand tools; no cutting or drilling of factory parts is required.

Notes

• Dinan publishes a single 2018–2025 application range covering the F90 M5 and the F91/F92/F93 M8; not every variant was offered in every year of that range. Dinan’s installation document (Revision A, 2020) covers the 2018–2020 F90 M5. Confirm your exact model and year with Speed Logic before ordering.
