It's a Gasket
in 2 years
It's a gasket, there's not much else to it then that. Seemed good quality and on a 2008 Toyota Corolla, it wasn't too bad of an install, just make sure to hook up the bottom rear hose of the throttle body that's very difficult to see when hooking everything back up. If done correctly should take about 1.33 hours.
