Built engine oil squirters?

What is the benefit of removing the piston oil squirters? Having them can help piston temperatures down and reduce knock. Why not just modify the piston to keep the squirters?

I love a good squirter

Two thought processes.
A street car run them with stock parts and any kind of boost. Because you know you will heat soak it in traffic, do long highway pulls etc.

Drag strip you control Temps, no need for a half a minute of run time.
Good parts and piston coatings tend to negate any benefits, and you are running more clearance on a non street engine.

On an N/A build with good parts where you may be spending time above 7K rpm, don't run them, they cause too much windage and steal oil volume from where it's needed. Windage is HP loss, and oil in the sump.

I define a street car as anyone who complains about piston noise.

I agree with all of this, particularly the definition of street car.

I believe Ford themselves even removed the squirters from a span of coyotes for a while stating oil aeration and starvation of oil elsewhere in the motor as reasons. Scuttlebutt so take that for what it's worth.

Maybe that’s one of the reasons why gen3 coyotes hold so much oil.
For a rod and piston daily driver build would it be better to keep or plug them?

Daily driver I'd keep them. Keeping the piston cool helps a lot with pump gas.

Unless your commute sees sustained 1G turns or extended time over 8K RPM I don't think there would be any advantage to deleting what Ford engineered in to the motor.
