CTS Turbo is proud to release an updated version of our popular F-series BMW B58 3.0L intake for M140i/M240i/340i/440i. Our intake kit is a complete replacement for the OEM system. The design intent was to create the largest, highest flowing intake on the market. Starting with a massive 6" velocity stack air filter, the intake features a 3.5" aluminum pipe that connects perfectly to the turbo inlet. No restrictions, no problems. We also added an extra turbo heatshield in order to keep air intake temperatures as low as possible. Without any extra tuning, peak power gains range from 12 to 20HP (fuel and elevation dependent). All of the components included in the CTS air intake system work flawlessly together to provide increased horsepower and torque throughout the entire power band and an aggressive race-inspired sound. This new revised version features a more rigidly mounted inlet pipe and a better sealing heatshield for superior performance without a CEL** Features:
  • Massive 6" velocity stack reusable air filter
  • 3.5" air intake pipe
  • CNC machined MAF sensor mount, updated design
  • Black powder coat for OEM look
  • Two heat shields with rubber seals
  • Great sound and power increase
  • Affordable price without sacrificing quality
  • Compatible with factory and aftermarket turbo inlet pipes
Fitment:
  • F22/F23/F30/F32/F33/F34/F36 BMW M140i/M240i/340i/440i models with B58 3.0L engine (2015-2019)
  • Fits LHD and RHD vehicles.
  • Fits RWD and X-drive models.
  • Does not fit G-series vehicles (2020+)
**Note: no CEL was reported, as this intake has been extensively tested on many different B58 vehicles.

About this Cold Air Intake

The CTS TURBO CTS-IT-340R air intake system replaces the factory airbox and intake tube to let the engine breathe more freely. Intakes typically bring a sportier induction sound and can improve throttle response, especially on turbocharged engines.

Frequently asked questions

How much power does an intake add?

Gains vary with the engine and are usually modest on a stock car; turbocharged engines and cars with other modifications tend to benefit more. Many buyers choose an intake as much for the sound and response as for power.

Is this intake legal in California?

In California and states that follow its rules, an aftermarket intake must have a CARB Executive Order (EO) number for the specific vehicle to be street legal. Check the product details for an EO number before buying for road use in those states.

Will an intake cause a check-engine light?

A quality intake designed for your car should not. Problems usually come from a poorly sealed connection, a damaged sensor, or over-oiled filters contaminating the mass air flow sensor.

How do I maintain the filter?

Inspect it regularly. Reusable filters can be cleaned and, if they are oiled, re-oiled lightly using the maker's kit. Dry filters can be cleaned or replaced according to the maker's instructions.

How do I make sure this air intake system fits my car?

Compare the part numbers listed on this page with the number on your old part or in your vehicle's parts catalog, and check the fitment information. If you are unsure, contact us with your VIN before ordering.
