CTS Turbo BMW N55 Performance Intake (M2, M135i(x) & M235i(x))

Cold air induction kit for BMW F-series N55

Unlock sharper throttle response, a deeper turbo intake note and real-world power gains with this high-flow induction system designed specifically for the F-series N55 six-cylinder. Developed after extensive testing, it keeps the air mass sensor readings correct while delivering the free-flowing performance you want. Expect improved drivability, smoother gear changes on ZF autos and a satisfyingly purposeful sound. Peak increases of around 10 to 15 bhp have been seen on otherwise standard cars.

Why this induction upgrade stands out

• OE-style hexagonal MAF housing in cast aluminium maintains accurate airflow metering and stable idle compared to circular tubes that can cause rough running and poor fuel economy.
• Large 3.5 inch mandrel-bent aluminium intake pipe with durable black powder coat for optimum flow and heat resistance.
• Reusable 3.5 inch inverted cone performance filter for maximum surface area and excellent filtration.
• Powder-coated airbox and heat shield that integrates with the factory front duct to feed cool ambient air.
• 4-ply silicone couplers and stainless steel clamps for a secure, leak-free installation.
• Complete fitting hardware and brackets engineered to stay rattle-free under engine movement.
• Subtle laser-etched branding for an OE-plus finish.

What you will notice

• Stronger mid-range pull and enhanced top-end breathing.
• Quicker turbo spool with a refined induction tone under load.
• Smoother downshifts and consistent fuelling thanks to correct air mass sensor geometry.
