I had the original twin pushers for 17 years. I also installed a Spal puller fan about 12 years ago. The puller is switched by a sending unit mounted in the intake, and I can operate it manually. The pushers were operated manually.
The puller does the job. After I installed it I rarely used the pushers.
One month ago I removed the bracket and pushers because they actually deflect a lot of air unless they are on. Since removing them I've seen a little quicker cool down while driving at low speeds of 30-45 mph.
I do like the look of the pushers, but I probably won't put them back on.
