Turner Motorsport - Carbon Intake System - G30 540i B58
Get ready for your B58 to have a quicker kick from the throttle and some proper intake/turbo noise that can be heard both outside and from the cabin!
Don't be fooled by the G30 540's subtle appearance, it is still equipped with the absolutely revolutionary B58 engine. Your sometimes overlooked 5 series deserves a performance upgrade with the looks and sounds to go with it!
Our new Carbon Fiber Intake is designed to pair perfectly with the appearance and equipment of your ride. This design features a heatshield, 4" conical air filter, aesthetically pleasing carbon lid and full carbon tube featuring a bell-mouth style inlet for optimized airflow . Pay attention to how well the intake fits in the engine bay within the confines of the OEM core support bracing, the carbon intake could fool you for a factory option if it weren't for the performance upgrade that comes with it! Stepping up the air-flow with a 45-50% increase over stock this intake is able to pull cool air in much larger quantities than the restrictive factory intake. The increase in flow relates to a better throttle response and with the increased air your computer will adjust with more fuel to provide a bump in power.
Why the upgrade?
Our intake looks and performs well but we cant forget about the best part about upgrading from your factory induction...the sounds, the TURBO SOUNDS! The G30 comes from the factory with an intake resonator designed to quiet down the intake for a tame and quiet driving experience. What's the point of having a car with forced induction if you don't get to hear it!? Our engineers completely understand what a weapon the B58 is and how important it is to hear the exhilarating induction that it can provide. This intake eliminates the factory intake muffler to let out the glorious turbo and induction noise. Once upgraded to this intake you car will feature turbo whistle and air induction noises that can be heard and enjoyed from both the cabin and exterior of the car. This is just the start to your performance upgrades for your B58 but let us tell you, this is one heck of a start to your upgrades, don't miss out on this aesthetically beautiful and feature rich intake that transforms the B58 experience in your G30!
