Beck/Arnley Fuel Injector P/N:159-1121
Beck/Arnley 159-1050 fuel injector for the 2008-2019 Toyota Tundra V8 5.7L, the 2010-2019 Tundra V8 4.6L and other vehicles delivers fuel into the engine for combustion. It is one of the Beck/Arnley fuel injectors, and it is a new part that matches OE form, fit and function.
A rough idle, a misfire or hesitation can mean an injector is clogged or leaking. These signs alone do not prove the injector is at fault, since a weak ignition coil can also make an engine misfire. For best performance, replace all the injectors in the engine together; this listing is one injector.
It works as a Toyota Tundra fuel injector replacement for the 2008-2019 Tundra V8 5.7L and the 2010-2019 Tundra V8 4.6L. The vehicles it fits also include the 2008-2022 Toyota Sequoia V8 5.7L, the 2010-2012 Sequoia V8 4.6L and the 2010-2022 Lexus GX460 V8 4.6L, and each of them takes eight.
