Paradigm Engineering's High Flow Turbo Inlet pipe is now available for the Toyota Supra A90/A91, BMW G2X M240I/M340I/M440I, and G29 Z4 M40i (B58TU/C 3.0L turbo engines). Paradigm Engineering's B58TU turbo Inlet pipe upgrade maximizes and smooths airflow from the intake to the turbo by removing all restrictions and increasing inlet diameter for more power and better turbo efficiency.
Paradigm Engineering's turbo Inlet pipe is a direct replacement for the restrictive OEM unit. The factory piping is not optimized for performance and will limit flow due to it's smaller diameter. The plastic construction of the OEM turbo inlet also makes it prone to cracking, under high pressures and increasing age. Our Aluminum B58 Turbo Inlets provide a wider diameter and eliminate the factory resonator, which results in more direct air flow to your turbo and increased induction noise.
Features and Benefits
• Maximize airflow to turbo
• Improves engine responsiveness
• Stronger than the plastic factory inlet
• Removes the factory sound resonator for improved sound
• Clean OEM look

I purchased the silicone hose, inlet pipe, and BMS intake with a filter together. There is a noticeable difference in sound compared to the baffle mod. Last night, the car experienced heat soak, with the intake air temperatures (IATs) reaching up to 122 degrees Fahrenheit at an air temperature of 67 degrees Fahrenheit. However, a few minutes after driving at highway speeds, the air temperatures dropped to below 80 degrees Fahrenheit. Once the turbo spools, there is a very quick and steady drop in IATs. It's worth noting that this combination does not have any heat shielding in the compartment, so it heats up quickly during stops and slow speeds. However, it only takes a few seconds of 9 psi to bring the temperature back down. The inlet pipe has a hump in it to accommodate the charge pipe, so I'm unsure if it's larger than the competition, but it still allows a massive amount of air flow. The throttle response is better with this setup. I haven't compared these numbers to the stock air box, but I know it couldn't perform better than 10-15 degrees Fahrenheit above ambient temperature. This modification is primarily for the sound and a slight increase in air flow. I will be adding some heat shielding as well, but it will only slow down heat soak, and the temperatures will still drop with driving. It's worth mentioning that temperatures do go up at wide-open throttle (WOT), but only by 1-5 degrees Fahrenheit.
