thank you so much for this!! saved me a trip to the dealer

[@eyebisllc4980]

This is the best video I came across, it was straight to the point. Thanks a lot mate!

[@jeffirick9034]

Very good explanation of how this is executed. Replacing the coil on boot was an especially helpful bit of news. I opted for Bosch 8505 Evo spark plugs. I had a hard time shelling out $30+ per spark plug.

[@jamescc2010]

How do Bosch 8505 Evo spark plugs perform so far?

[@jeffirick9034]

@@jamescc2010 Haven't missed a beat. I can't tell any difference betwixt them and the original ones.

[@Matthew-ei2ou]

I found out the hard way you have to have this specific thin walled 14 mm socket because of the sleeve the spark plugs are in. I missed that in the comments & video. Lesson learned. Great video.

[@nesone6520]

I did mine with a 9/16 spark plug socket lol

[@stephenmurgan]

Very professional job. Thank you.

[@HSTL_Team]

Why wasnt this at the top of the search? Thanks for this

[@17chucksters]

Clear and concise explanation. Thanks.

[@mcguinness40]

Great video. Gonna do the electrode swap also. Why not. Had just watched a guy drop his plugs in. Yikes. One question. Did you have to gap them or were they were already.

[@DavidStumph]

The ones I bought were pre-gapped. You’ll need to check on whatever you buy, to make sure nothing happened in manufacturing or shipping.

[@alohawaii222]

Thank You for the very detailed and to the point video. Do these same procedures apply to a 2018 Accord Hybrid engine? Would the same spark plug fit for a hybrid or is there a different one?

[@DavidStumph]

Doesn't look like it's the same. Please research yourself to confirm, but it looks like this would be the correct part for your vehicle model: www.hondapartsonline.net/oem-parts/honda-spark-plug-dilzkar7d11s-ngk-122906c1a01

[@alohawaii222]

@@DavidStumph Thank You!

[@ixiwixi]

What torque wrench did you use? I keep reading horror stories about torque wrenches snapping plugs because they didn't click. Otherwise, this video gives me the info and confidence to change the plugs.

[@JohnS-il1dr]

Use a beam type torque wrench. Its much better than the clicking type. Mine clicked 5 ft lbs after the set limit.

[@ixiwixi]

@@JohnS-il1dr I ended up picking up a Quinn digital torque wrench adapter and used a regular ratchet. I'll be sure to check out split beams though.

you drop this 👑

[@alexxisalexca]

great vid man!! thanks for

[@Shot.byJude]

Thanks!

[@hyperion2005]

Nice video short and sweet

[@jacobmichel2800]

Thank you for the video! Just question I could not find the bottom coil boot, all I could find was the coil assembly plug top. Did you have a link for this by any chance?

[@DavidStumph]

Added the model number to the video description

[@ThunderGodMark]

Awesome video! Do you know all the service intervals for the accord? Annoying to go to the dealer and fight them for it

[@DavidStumph]

The Maintenance Minder will guide you as the car senses maintenance is due. The codes it will display can be referred to here: owners.honda.com/servicemaintenance/minder If you would like to address things in advance, though not the most holistic guide, this will help: www.valleyhonda.com/service-department/service-tips/honda-accord-service-schedule/

[@cwdl2004]

How often do we need to replace the coil boot kit . Every Spark plug change ? ... tyvm for the vid..

[@DavidStumph]

Most manufacturers recommend every change.

[@evianmedina8498]

Hi, great video, thanks for sharing. Do you happen to know what the correct gap is for the accord. I checked the manual and did not find it and my new spark plug are not all the same gap. Thanks in advance.

[@DavidStumph]

0.030". Also, I linked in the description where to buy pre-gapped spark plugs. NGK is reliable, but I’d recommend buying from a dealer and not a knock off distributor on Amazon for these. The model number of the plug I used is in the title of this video. Good luck.

[@nesone6520]

@@DavidStumph Where did you get that information from? The worker at the auto parts store did a google search and it came up with .044. The Autolite plugs that I bought showed in their computer as being .030, but when I checked them, they were in between .040-.045 on my gap tool.

[@DavidStumph]

Interesting. Rock auto lists .030 for all replacement options. The model I listed and used are oem ngk. They were gapped .030 when I measured. I try to avoid sifting through forums when possible. Hope that helps.

[@nesone6520]

@@DavidStumph When I pulled the original NGK's from my car, the gap was in between .030-.035 (my gap tool is limited to certain sizes). The reason I'm researching this, is because my car gave the check engine code P0172, which means it's running too rich. I left the Autolites at .044 when I installed them, cleared the code, and have 3 days so far without it coming back on. I'm crossing my fingers it stays off, and monitoring my MPG's as well.

[@JohnS-il1dr]

​@@nesone6520i got that same code. Cost me 1500 usd because the injectors needed to be replaced. Common issue with 10th gen accords

[@Theblistaknight]

did you change them with cold or warmer engine?

[@DavidStumph]

It was cold. Sat in the garage overnight.

[@alexanderolimpo2671]

thanks

[@blackhawks1870]

David how’s your car running?

[@DavidStumph]

Great

[@kidnman4605]

Im having a difficult time trying to get the coil boot to snap into place with the spark plug when inserting it into the well. You know that click you feel when pressing down? is there a method to this? isn't it supposed to be snug into place?

[@DavidStumph]

There wasn’t really a click or snapping into place when I did this. I show pressing firmly with your palm until the ignition head is fully seated and flush with the engine. That should be all that’s needed. Hope that helps.

[@gbrocco2000]

Where did you get that swivel socket at? Great video

[@gbrocco2000]

Also, does this apply to the 1.5T?

[@DavidStumph]

I've added a link to it in the description

[@DavidStumph]

Yes, mine is the 1.5 Liter EX-L

[@stevenfabian5035]

When you should change the spark ?? Every how many miles??

[@DavidStumph]

This is mentioned in the video

[@franknicolosi6970]

Hey David, do you know the part number for the ignition coil boots that you have to change?

[@DavidStumph]

I used these from RockAuto - STANDARD MOTOR PRODUCTS SPP221E I updated the video description for others.

[@yusufkohgy9122]

I have 2019 Honda Accord 1.5 Where do I purchase new spark plugs)

[@DavidStumph]

There is a link in the description of my video. I’d recommend Rockauto.com as an alternative.

[@ericcampoverde9543]

the link you posted is it just for 1 plug ?

[@DavidStumph]

That link is for one plug.

[@andyrojas798]

The sparkplugs are pre-gapped?

[@DavidStumph]

The ones I linked and used, yes.
