Have you smelled fuel vapors coming through the heater vent on cold mornings? Maybe just caught a whiff of gasoline vapor when you open the hood? Have you checked your injector O-rings recently? These replacement fuel injector O-rings will prevent fuel leaks and are a good idea when swapping injectors. These kits fit all OEM and OEM replacement injectors including Deatschwerks.
Each set includes O-rings for four injectors.
