How to change Toyota Spark Plugs on 4 cylinder engines

A Toyota Master Diagnostic Technician shows you how to change Toyota spark plugs on 4 cylinder Toyota engines.

Welcome to a brand new series on my Channel on How to maintain your Toyota the DIY edition. In this series I will go over all the commonly needed Toyota maintenance so you can do it yourself the right way.

Find the informational How to maintain your Toyota series here:

In this second part of this series I cover all Toyota 4 cylinder engines spark plug replacement.

I'll talk about the removal and installation procedures. The importance of torquing the spark plugs to the correct torque specifications. Also I will cover the brands that original spark plugs from the factory are which are Denso and NGK.

I will also cover basics of spark plug reading for Toyota. Also some tips on removing the connector and dealing with broken spark plug ignition coil connectors. Also the importance of the ignition coil seal.

And I will also cover how to identity factory Toyota spark plugs.

Questions? Comment or email please note that it takes me sometime to get back to you via email but I always will in the end.

Great job of explaining, spent 44.00 for plugs and 25.00 for a torque wrench. Took 30 minutes and saved over 100.00 from the quote.

Took me 5 hours to finish my 2007 Sienna spark plugs. The 3 plugs in the back are the most time consuming.
While I was there, I changed the intake plenum gaskets and gave the throttle body a nice shower with TB cleaner an let it dry while finishing the plugs, and I gave it a new gasket. Finalizing the job with new air filter and PCV valve. All OEM TOYOTA parts from my local dealer. Also I sprayed the MAF sensor. There was nothing wrong with the van but it was time to do it after 13 years/130K miles.

Damn bro, in the DIY world, you're a breath of fresh air. Your videos are so direct and to the point with amazing tips in the middle, makes you watch the whole thing! Excellent work!

Just changed my spark plugs yesterday on my 2015 nissan xtrail (rogue in the US). This was my first time doing this job. Took me about an hour. Took my time coz I was afraid I was gonna break something. Gladly, everything I did was on par with what Mr. AMD showed in this tutorial. Torqued them down to 17 ft lb. Now the car runs better. It also eliminated the knocking issue when I was backing up the car into the garage. Didn't use anti seize n dielectric grease because service manual didn't recommend using them. I'm a sucker for diy car videos and Mr. AMD makes great diy videos. Thank you 😁

When I replaced the plugs in a 2007 Matrix I used Laser Iridium NGK brand which cost about $57 for 4 in Canada. What bothered me the most was not having an air compressor hose to blow away the dirt. I used an aerosol canister instead. I looked at the gaps and did not use anti seize on the threads. Used great care in rethreading the new plugs and torqued them to 18 ft-pounds. I brought them from local auto parts store. I find local Toyota Dealer’s prices for parts reasonable though and try to always use OEM parts.

Another great video, thanks 🙏
One tip from me.
Once you disconnect the wires and remove the coils work one cylinder at a time, take the old plug out, inspect it and put the new plug in, torque it to 25Nm and move to the next one. Once all plugs are replaced insert all Coils back and torque to 10Nm. Never use any anti seize. Do not wait for 120k miles for change, just 60-80k miles max, these plugs can go even up to 200k miles however these dark marks shown indicate leakage that can actually damage the coils and then expensive replacement. 👍

I appreciate your help and knowledge. I was just quoted $230 to change the plugs for 120k maintenance. I ordered new ones and will do it myself and save $200. Love my 2014 Avalon Hybrid. I purchased it after watching your video with the Avalon Hybrid being the hidden gem of your car choices!

Ive had nothing but older vehicles my whole life, just bought a 15 camry, was concerned about maintenance schedule in owner manual. You have given me hope to take this one past 300k 💙

[vaughnavesian]

As a DIYer by choice, thank you for all your videos and advice. Also thank you for your quick response and advice on more then one occasion. Much appreciated.

[brianreichert]

Thank you AMD - I just bought the plugs yesterday, but was worried about installation until I watched your video. Thank you so much.

[stephanel.]

I LOVE your new maintenance series!! It is so well done and those tips and tricks you give are priceless (like torquing or not, torquing specs, what to do if you break a connector tab, etc). Most other videos won't go to that extent, keep up the great work!

[christopherm]

When the wire plug connector lock tabs brake, I use the small zip ties to repair them:) One looped around the coil and then another through the connector tab and then tie the two together. No potential misfires. I've never thought of using the gasket maker. Thanks for the tip and another great video!

I just changed the spark plugs on my daughters 2015 2.5 Camry. Replaced with Denso spark plugs, but the TT Iridium. (Iridium pointed laser welded on the electrode). Runs perfectly!

[yakeetywinkle]

Useful channel thank you. I didn't hear you mention when to change the spark plugs with respect to engine temperature. Cold, Warm or Hot? I would guess cold. Thank you. I have a 2011 Corolla S with 301, 700 miles. Still runs like new. I change the oil and filter every 5000-7000 miles, full synthetic. When I change the oil, it still is not black. It is a dark golden color. Only changed the fuel pump, alternator (3 times), struts, motor mounts and constant velocity joints and drive shafts, a/c compressor and condenser coil and blower motor (live in Houston, tx). A very strong car. Goal in 500, 000 miles. I enjoy your channel. Thanks

After seeing this video, I checked my Toyota dealer service reports and compared it with the service manual. Found out that my 2007 Toyota (while always having the Toyota service intervals) was having Spark plugs (no iridium) from 2015 that already did 84500Km. The engine was performing nicely so that did not reveal that the spark plugs were rather old. Replaced them with Genuine Toyota Denso spark plugs and life is good. Thanks for the nice instruction.

There are lots of counterfeit denso plugs around. You get what you pay for! I was told BY DENSO to only buy from a Toyota/Lexus dealer or Advance auto.

[pokedude]

spark plugs are the DIY job I've finally caved an gotten myself a torque wrench for. Not so necessary for basic things like oil change or air filters, batteries and whatnot but now I can swap my own tires out for winter too without worrying about if I got the torque right.

[bachle]

Thank you so much for your video. It gave me the confidence to replace my spark plugs today. My car runs smoother than ever after replacing them.

[njsongwriter]

It's been a long time since I changed spark plugs so I watched this video a couple times and then changed the plugs on our 2009 RAV4. The vehicle has just over 70, 000 miles on it but since it's a 2009 model and thus about 12½ years old, I figured it might be a good idea. Everything went as smooth as silk. No trouble getting the old ones out or the new ones in. I put in the same Iridium type of plugs that the vehicle had in it as OEM, Denso SK16HR11 3417 Iridium Long Life. Torque specs I found said 18 ft.lbs. for the plugs and 7 ft.lbs for the bolts on the coils.

The mpg has been lower now than it was last year. I'm hoping the new plugs will help. However, the decrease in fuel economy may be due to installing wider tires with a higher rolling resistance.

Thanks AMD for this video.
