Denso coils are good for another 150,000 miles
If you want to aftermarket
DENSO 673-3204 is best
Grab some Denso coils from Rockauto. Shouldn\u2019t take ten minutes to swap them. The locks on the plugs are about guaranteed to snap (if they\u2019re even still on it), don\u2019t panic, just plug them back in and don\u2019t worry about the locks. The four 2AZ Yotas I own and the 3MZ Sienna have been just fine without them.
I got the Denso from Amazon it wasn’t cheap but you don’t want misfires with after market cause the car will idle and drive like shit.
I went from sub 0.030" spark gaps to the stock above 0.040" spark gaps without getting spark blowout for 4 years now.
I replaced the OEM coil with an MSD ignition coil earlier this year after having similar misfiring issues. Haven’t had any issues since.
I used Denso coils on my 2016 2.5L SE and they are literally the Ford coils with the Ford number crossed out and a sticker slapped on to cover most of the number.
I always use denso coils. Can't trust others.
I ran a Blaster 2 on my old car for a bit. Idle was a little smoother, but it was probably because the coil on it was crap. No real performance gains expected.
I have a 2013 eco-boost F150 and I put some Denso ignition coals on it but I don’t think they did the trick.
