@whatbimmerg30: After some R&D I made an air duct for the G30 540 (May also fit 530/740) made out of PPA-CF with a gromet that’s made out of TPU 95A Benefits: Better engine response Steady IATs (about 20 degree above ambient) Quick IAT recovery after a pull Works with stock and/or upgraded intake manifold/heat exchanger. To also help complement this air duct I recommend to buy a heat shield and turbo blanket HMU on instagram purchase: Cursed_540 ##g30540##bigboostturbo##b58##3dprinting##cadsoftware
