Great product that works well in my 2005 Pontiac GTO ...
This product worked perfectly for my 2005 Pontiac GTO with the LS2. Just make sure to clean the intake manifold fuel injector bosses really well prior to using these fuel injector o-rings. Otherwise you may get one or many vacuum leaks indirectly to the new o-rings. Also using a little engine oil will allow the injector o-rings to slide into the intake manifold injector bosses without rolling. Rolling can also cause vacuum leaks. Great product that works well in my 2005 Pontiac GTO turbocharged LS2.
