Heat is the enemy of power, and the last thing you want is hot coolant heating your charge air even further right before it enters the charge cooler, but this is what BMW has done on the S58. This is done for emissions and quick warm-up purposes. However, If you are looking to make power on the S58, and are upgrading your charge cooler, or adding PI. While you are there, it takes 30 seconds to remove the coolant lines from the TB connections and replace them with our billet coolant delete kit. This completely removes the coolant from the Throttle body and provides a bypass for the coolant. Simply remove the two lines going to the throttle body, and run our hose in their place. You leave the coolant fittings on the TB open and avoid any unwanted heat being introduced into your charge tract. In our opinion a must for full effort builds. We take the work out of it for you. Kit included: One Plug and Play TB Coolant Delete Hose Kit Features: Billet 6061 Anodized coolant fittings for long leak-free life Reinforced 7-ply silicone hose for strength and longevity Vibration-resistant crimp clamps 100% plug and play, NO cutting or removing factory clamps or hoses. Fully reversible
