Tuning my BMW M4

[marwanch82]

Hi Guys

I just replaced my stock exhaust system with AC Schnitzer exhaust system and installed AC Schnitzer ECU hardware performance upgrade.

Is there any need to upgrade the air intake and/or the intercooler to handle the excess stress on the engine?

If yes, which brand you'd recommend i.e. AWe vs AFe vs Armaspeed.

Thanks

For intake? Why not just BMS? There's no performance gain on intakes iirc

As far as suggestions, downpipes and chargepipe?

Catless downpipes (lots of good options VRSF, Active Autowerke, Evolution Racewerks)

AWE Heat exchange

As for intake , they all give you the same performance gains on a tuned car ~10 whp after 5000 rpm .. i would save some money and get the BMS intake.

If you want a fancy intake, check the AWE option
