Should You Replace Coil Pack with Spark plugs? (At the Same Time)

[@unebonnevie]

I ALWAYS replace the 3 coils in the back for V6 engines, because it's hard to change the 3 spark plugs in the back. Spark plug change, e.g., for Lexus cars, typically at 100K miles are hard AND expensive. You don't want to pay for labor again to replace the back coils afterward! Save the old coils for the 3 in front, which are easy to replace; even Homer Simpson can do it!!!

In those cases its a good idea😊

[@HonestMechanicChannel]

Great advice! Thanks for sharing

[@jwrn4u]

Correct

[@simplyraw1369]

I appreciate your insights shared! My dad was my mechanic and sadly he has died. Im not standing on solid foundation financially speaking, so I am forced DIYer Especially since my husband too has passed. Grateful in the fact I was my dads small hands and enjoyed tinkering growing up. The only issue I have now is I find it hard to trust most mechanic shops! I now rely on the internet and end up reading and watching you tubes until I can understand the reasons of whys and ifs with good sense. And this you shared makes good sense to me! thanks again ✌️

You’re doing the right thing, I had a engine problem, went to the dealer and they replaced 1 spark plug in the back and the coil pack with it, thousand bucks 😢, when I got it home I pulled everything apart and replaced the rest, less than 200,

And always use high quality plugs, like iridium. They will last around 100.000 km. And ensures a good spark and clean combustion.

Spot on!

If u can use spark plug non foulers. Makes em last even longer. Even the old copper kind.

After several P0300 misfires I changed out my plugs with genuine OEM NGK iridium spark plugs and closed the gaps from .032" to .028" due to reading many forums that closing the gap will minimize the misfiring issues. Additionally, for peace of mind i emailed NGK technical support and asked them if that was going to harm my plugs as they're iridium and not supposed to be regapped. Per their reply .008" is their maximum recommended distance to close. After installing them and installing 4ea. Zz performance coils I'm noticing the vehicle runs significantly better. Fingers crossed no more Check Engine Lights (P0300). Vehicle has 64,000 miles and is a Saturn Sky Redline

I just finshed changing the plugs and coils, and cleaned the throttle body on my 2016 canyon with 194k. I bought the truck with 80k on it so I thought it was time for both. The other reason for doing both is that you need to remove the intake manifold to get to some of them. Just made sense to me.

Lol i have 2012 v6 coils are 100 buck each thanks for great video and advice I didn't need to change them just plugs

[@lalagummybearcarrot]

I just had my spark plugs replaced. Wondered if i should do coils. Car has 135k miles on it. 2006 civic

[@dragoonshazil]

Don’t replace them if there is nothing wrong withe them, I just did the same on my ford e250 I replaced all of them and ended up causing multiple misfires.

Thanks 👍🏻👍🏻

New spark plugs have a smaller gap than worn spark plugs, so they work with a lower voltage. Replacing spark plugs does not put a higher voltage demand on the coils, unless you have the wrong spark plugs.

I had my spark plugs replaced, the coils are burnt and should be replaced soon, I can use them for a little bit before they cause damage to the new spark plugs

Bought a 2003 XJ8 with 16,000 miles (verified). The car was sitting in a garage and not driven for 5 years (due to age of owner). Changed all fluids, tires, filters, a few rubber-related parts. The car passed inspection. The problem is engine and warning lights and limp mode popping in after about 20 miles of driving. OBD indicating fault codes for throttle body and for ignition coils and spark plugs in cylinders 1 and 3. Throttle body and sensor cleaned and now I'm inclined to replace all plugs and coils. Can anyone think of an argument against doing so? Additional info: the car was purchased by an elderly woman in Santa Monica, CA and primarily driven short distances on secondary roads in her neighborhood for 15 years before being garaged. I know the daughters and they do not think their mother (now deceased) ever drove on the car on a highway. Stores and social functions. Back to the sparks and coils... thoughts and opinions greatly appreciated. As well as manufacturer recommendations for sparks and coils (leaning towards NGK. Also, I'm not a mechanic but have been under the hood and car before including changing the air suspension on my wife's 2004 XJ8 to the Billstein shocks and coils kit (which I prerfer to the air suspension). Thank you for taking the time to read this post.

[@christyblack8693]

Okay, so what if it's the opposite situation, what if I do need new coil packs, then is it recommended to replace the spark plugs along with the new coil packs for better engine operating quality ?

[@Drew858pb]

Of course

[@bjmarchives]

Well considering the price of plugs, why wouldn’t you.

[@GregsAutomotive]

As long as you change bad spark plugs ignition coils usually last.

[@jwrn4u]

It takes me about 12 hours to accomplish the rear plugs on my transverse 3.3 Santa Fe, I take the intake all the way off and clean everything, vacuum out leaves and stuff, clean the throttle body , etc, then I’m not leaving a coil pack in there after all that, I recently replaced the injectors also ( some people are refurbishing them, that ain’t me) then it’s about 4-6 hours replacing everything and then 😬, the moment of truth, that’s a real anxiety event when you turn that key

[@1989marcomendez]

Well after 25,000 miles i guess its ok to replace my ignition coils,spark plugs and injectors
