Review on High-Quality Flow Matched Fuel Injectors for Ford 4.6 5.0 5.4 5.8 - Replaces 0280150943 (Set of 8) by Jake Larson

I installed them then had to remove them for another service. All but one left the bottom half of the injectors (not just the o-rings which would have been normal, they left the filter, o-ring and bottom half of the injector) in the intake manifold bosses, although I was careful about my removal process . I wouldn't recommend them for more than one installation and then I couldn't tell you how long they would last. However, the company processed the return very quickly and refunded my money.
