Most of the aftermarket fans sold are pure garbage.

You'd be a lot better off with a fan like the HHR / 3.8 Taurus / 4-cyl contour single fan on a 22"

If you had a 26", the V6 Contour fan is basically the greatest thing since sliced bread. I don't even need the high speed the fans have.

I'm also running a contour fan, EFI, Aeromotive 340lph fuel pump, and everything else on the car on a 78a 12SI Delco alternator.
