Review on Improved Fuel Injection Nozzle O-Ring Kit by Beck Arnley 158-0894 by Francisco Yim

Revainrating 5 out of 5

They will fit a 2001 Tacoma 4 cylinder.

I have them on a Tacoma 2.4 4-cyl. There are two thick O-rings running on either side of the injector, a small one on top and a large one on the plastic cup. These cups are extremely hard to come by and usually need to be broken, so it's recommended to leave them alone. I didn't need any of the top thick O-rings either. The factory service manual says something about Tacoma using it to meet California requirements. I do not know what you are talking about.

Pros
  • High-quality materials ensure a tight seal on the injector nozzles to prevent fuel leakage.
Cons
  • Some little things.
