Fuel Injector O-Rings - 1ZZ 2ZZ

Set of 4 brand new Toyota OEM fuel injector isolators and 4 o-rings

These are the rubber donuts that go between the fuel injector tip and the cylinder head on all 1ZZ and 2ZZ engines. Over time these isolators get hard and do not seal properly. They are also lost or damaged frequently during fuel injector installs. Don’t reuse those dirty leaky old isolators, replace them with fresh ones.

These are the rubber o-rings that go between the top of the fuel injector and the fuel rail on all 1ZZ and 2ZZ engines. These o-rings are often torn during injector changes and do age, potentially causing leaks if reused. Don’t reuse those dirty leaky old o-rings, replace them with fresh ones.

One set of 4 required for a set of 4 OEM or Deatschwerks injectors.
