Replacement Fuel Injector Seals and O-Rings

In order to properly replace a set of fuel injectors a new OEM Fuel Injector Seal Kit is required.

You will need to order 1 Fuel Injector Seal Kit per injector to insure a leak proof installation.

These products are often referred to as Fuel Injector O-Ring Kits.
