No-toil filters might be cheaper, but it's a wash because you have to use their oil and cleaning solution/grease. It's usually sold as a kit.
I would venture that the tolerances in newer aluminum engines are much more precise and have less allowances for dirt and grit. Normal maintenance and proper seating of the air filter is enough to avoid this.
