VCM Muzzler - long term review (5 years 70,000 miles)

11/26/2021 Mileage Update 100,723.

A review of the VCM Muzzler II installed on my 2014 Honda Odyssey after 5 years and over 70,000 miles of use. Honda's VCM (Variable Cylinder Management) operates by shutting down the engine from 6 cylinders to 4 cylinders, then to 3 cylinders, to improve fuel efficiency. VCM can cause issues with your engine such as foul spark plugs, oil consumption, and bad engine mounts. VCM Muzzler solves that by keeping the Honda 3.5L V6 (J35) in 6 cylinder mode.
