The Paradigm Engineering B58TU BMW silicone intake pipe upgrade smooths the airflow from the intake to the factory turbo inlet by removing the upper factory sound resonator and the lower accordion section of the air inlet pipe.
We also recommend installing our upgraded B58TU turbo inlet. It is not required but highly recommended for tuned vehicles to better maximize air-flow.
Features and Benefits
• Maximize airflow by letting more air smoothly enter your turbo with little to no restriction
• Removes the upper factory sound resonator
• Removes the lower factory accordion tube
• Works with the factory BMW intake
• Better sound
• Clean look in the engine bay
• 2020+ GR Supra Mk5 B58 3.0L 6 cyl.
Only tested with the factory BMW B58 intake, Fitment on aftermarket intake systems can not be guaranteed.
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.
14 days and I still haven’t received it.
Tracking shows it’s still in transit so not your fault but you asked for a review
