To achieve Stage 2 tuning on your BMW M340i, start with an aftermarket intake. Brands like AFE and Eventuri are popular choices that improve airflow significantly.

16

Great info! Pairing that with an upgraded intercooler from Wagner or Mishimoto can further support the gains by keeping intake temps down.

17

Definitely don’t overlook the exhaust system. A cat-back exhaust will not only boost performance but also give your M340i that aggressive sound. Look into Akrapovic or Remus for quality options.

18

Absolutely, but remember to check local emissions laws. Some setups can be too loud for daily driving!

19

Make sure to also consider an upgraded charge pipe. The stock one can fail under increased boost pressure, and companies like VRSF produce solid replacements.

20

Good point! A quality charge pipe can save you a lot of trouble down the line, especially if you’re pushing more power.
