![ATM Turbo Outlet Hose O-rings](http://streetdrivenindustries.com/cdn/shop/products/image_f739ecaa-0b9e-4624-9684-deaa58cd2d1f_{width}x.jpg?v=1663872099)
The M57 ATM turbo outlet hose is a great upgrade over the stock hose. We have found when pairing it to other aftermarket intercoolers, the o-rings tend to tear when installing.
Aftermarket intercoolers(including VRSF) have a tighter tolerance with the aluminum connections than the factory plastic units. These tighter tolerances make it very difficult to install the ATM hose with the o-rings that come with it.
We now offer these slightly smaller o-rings(priced as a pair) which easily install and have been tested to be leak free on VRSF upgraded intercoolers.
