11-03-22, Mileage-131,452: Installed another OEM Mazda ignition coil(part #BP6D-18-100A-9U) since the other aftermarket was replaced I thought it would be a good idea to replace the other.
new one on the left and old one on the right


Apparently, they both were problematic as I noticed a decrease in exhaust burble after replacing each one. :bang: Miss that but not at the expense of the motor not running correctly.
