Ignition coils

Anyone here have issues with using Duralast ignition coils? I’m getting constant misfire readings and wondering if it’s because of the brand of coils I’m using. Should I not be using them in my Tundra? I have Denso plugs, but Duralast ignition coils.

 

When it comes to coils I try to stick with Denso. There’s also an issue with fake name brand plugs from places like Amazon. You may want to check the gap on your plugs as well.

 

Duralast coils are not good on these trucks. Order Denso from somewhere reputable. Dealer or Rockauto would be my go to on these. Toyota’s electrical systems are pretty sensitive overall. Anything sensor or electrically activated, go with OEM Denso parts.

 

Thank you! I’ll see if I can return the coils I have and replace with Denso. Much appreciated.

 

Rockauto? I’ll check it out!

 

Get rid of the Neverlast coils. Only Denso. RockAuto has them for 1/2 what the parts stores sell them for.

 

A rule of thumb is to use plugs/coils/sensors from the engine computer vendor. Bosch ECU -> Bosch spark plugs, coils, oxygen sensors, MAF, MAP, IAT, etc. Denso ECU -> all Denso.

 

Thanks All - I guess I learned my lesson. Hopefully, I can return the Duralast ones I got from AutoZone.

 

Is there a service interval for replacing the coils? My 2011 has over 185k miles, I've changed the plugs twice over the years. The coils have never been changed as I haven't had any issues.

 

I had 250+k miles on original coils in a 2005 vehicle. Replaced them for no good reason. Keep the coils wire harness healthy, make sure they have a good ground contact via bolt to the valve cover, and it seems they can live indefinitely.

 

I ended up having to replace my alternator and was told that I received an error on the coils also. Never had an issue before, so who knows.

 

The duralast ones should be lifetime warranty. Not sure they'll give you your money back for them though unless you just bought them.
