Review on Enhanced Denso DAC673-6005 Ignition Coil for Optimal Performance by Johnny Grant

Purchased to fix a misfire problem on a 2007 Mazda 6 Sport V6. Got P0306 and decent engine chatter due to misfire. I don't know which cylinder it was, but it's likely that it was one of the three under the pressure valve. Decided to replace all 6 at once (including the spark plugs) as the car was approaching 70,000 miles anyway. Fits well, arrived quickly and well packaged. After the replacement, the car started immediately, there are no more passports. We'll see how long they last, no problems so far.
