THANK YOU for making this video 😊

9/29/24: THANK YOU Instructor! Thanks to your vid I successfully installed my new battery on my 2010 CX-9: Well done and I am grateful to you! Roxie in Mpls

How often would you recommend changing them? thanks

I was denied noise canceling headphone for when I do online training.. ( ADHD & ASD ) from a multi-billion dollar telecommunication company.. but they will provide me with print outs when. They can remember or someone is available to do so .

This is the best video I’ve watched for this procedure. I used this method to assemble and install my 6112/5160 combo on my FJ, but I remember having to loosen my a-arm cam bolts to do it( I also had a front sway bar at the time ). I removed my sway bar a few months ago and I love it. I’m about to swap front springs again, and found your video when I was looking to brush up on the whole procedure. I noticed that you never loosened the cam bolts when you made this video. Is that because you are also running without a sway bar? I really hope I can skip that step this time around. Thanks for the excellent video! Top notch work!

It will mess up your cat

I recently tried to change spark plugs on my cx9 2017. Couple of things i learned and want to share my experience with you. 1. You might be able to change 1st and 2nd plugs, but 3rd and 4th coil are the hardest part to put back. I tried for several hours and ended up cross threading the coil bolt. I would highly suggest please get it done by Mazda professionals. 2. The mechanic disconnected the hose in order to put the coil. 3. My car was at 98k kms and spark plugs looked pretty good. If I knew it i wouldnt have changed them cuz they look pretty good. 4. I would prefer Mazda OEM spark plugs over NGK. 5. Spark plugs are changed once in a while, i found it convenient to get it done by mazda professionals. Just few learnings. I have always changed spark plugs of my older cars but Mazda cx9 spark plugs are not easy to change.

Forgot to disconnect the battery

Excellent work . Thank you

Uhm.....that piston has 5 ounces of carbon on it..

I drilled a small hole close to the TB into which I insert the small tube. Once done, I twist in a screw. Easy Peasy

Should i apply dielectric grease to the ceramic part of the plug?

Hi, is it ok if instead of using the 1/4 inch drive 8mm and 10mm sockets plus ratchet that i were to use the 3/8 inch drive versions of those? I am new to this. This is the best tutorial i have seen for this.

Bro I have a 2018 with about 50k miles only. It seems to have oil delution. Dipstick is up about half a quart and oil smells like gas. Does yours have that?

Good video, thanks

I love people who go straight to the point

Iridium plugs will easily go 100k miles on an engine that is running properly, not sure why they are telling people to change them at 40k.

awesome video! how is your frame so clean and look new😂

I drove through highwater in my Infiniti G35X & hydroloked my engine & the next day it blew. I replaced the engine but for some reason the engine kept going into limp mode. The dealer couldn't figure it out so I went online & figured it was dirty MAF sensors and they told me they dont clean MAF sensors so I drove the car off their lot. Parked & cleaned them like this & it ran perfect 👍

What did you do to make it easy to remove the spark plugs. You said they were wet.

no dielectric on coil packs?

Thanks for the explication , someone knows if we can start the engine pressing the buttons of the key?

Appreciate the video. This method cleared my check engine light on my 16 Mazda cx-9 and it’s been a few months that it’s been driving great after doing it 🙏🏼

Thank you for the video, this was super helpful and i was able to replace my plugs today. Just a small mess up, i dropped one of the bolts holding the metal bracket behind the engine and I am not able to find it!!! Do you have any idea what is that bracket called, i wanted order the replacement bolt as i just cannot seem to find it behind the engine!!!

Thanks mate

NGK specifies 18-21ftlb for 14mm plug w/aluminum head. Is 13ftlb correct!? Do you have reference? Tks

Superb Quality video thank you for making this video.💯💥💢

Excellent video, I just ordered the parts and soon be ready to change the spark plugs

Thanks for the video What is the improvement on gas. Consumption of full tank, total milage before and after cleaning with the CRC?

Great Video. Also applies to the 2018 Mazda 6 with the same engine (2.5 T).

thanks so much! saved me $$$

This an excellent video that explains everything.

Thank you!

Tip: I did this but when I started the car it was misfiring horribly. The ignition coil must be inserted back at the right angle otherwise it will not make contact with the plugs thereby misfiring.

Am I correct in noticing that cylinders 1 and 4 have the cups on top of the cylinders to reduce knock? Super interesting

Do you need to disconnect battery first before changing battery or straight on swap?

Anyone know where pvc valve 2018 2.5 engine is

Great clear explanation. Thank you.

great video learned a lot about replaing the spark plugs, just wondering at the right rear of the engine cover there seems to be a hose disconnected when you turned on the engine, is that something to look out for ?

thanks 😊

Removing that metal plate and working with it seems quite annoying.

Preparing to do my first 40k plugs on the 2.5T. FWIW, NGK advises to not use anti seize on the threads, stating that they come from the factory ready to go.

Did my own cx-5 and its all thanks to your video. Thank you.

Perfect dude thank you. The dealership wanted 150 dollars to do this for me.

Thanks! Your simple but informative steps helped me in finding how to open the unit without breaking the fob.

You may want to change the title of this video to mention it also applies to the CX-5 models that have a turbo - Same engine and turbo as the CX-9. I’ve got a 2020 CX-5 Grand Touring Reserve with the turbo motor and your video was exactly what I needed. Same requirement to change out spark plugs every 40,000 miles. Thanks!

Thank you 🙏

Thanks for sharing this !

I’m having a rough time getting my coils in even wit grease any idea as to why
