2010-2019 Lexus GX460 NGK Laser Iridium Spark plug installation

Excited to install these Laser Iridium spark plugs into my car. They're the latest series in NGK OEM lineup of Iridium series. Laser series lasts 80k to 100k miles versus only 40k to 50k in a normal iridium spark plug. These are 6x harder and 8x stronger than platinum. In a V8 engine, these also increase your fuel economy as stated on many websites.

Thanks for making this video! There aren't enough 460 videos out there. Good to see that people are starting to make videos for the GX 460.

I think i started making videos just for that exact reason. I could not find any content on my car when i first picked up a GX470 a long time ago. I"m glad some of this can be useful to you and thanks for the comment!

Thank you for taking the time and filming this. I know that you just want to get it done and filming makes the process much longer, but I appreciate you!

You are incorrect. My cameraman is actually a 24-year-old film student intern named Cindy. She agreed to film my tutorials while in the nude in return for being on my television crew for college credits.

[@chenyang2377]

Thanks for the video, just replaced mine with Denso Iridium TT. A bunch of various length extensions and swivel head ratchets really help. One tip for removing connector from coil: use a small right angle pick to lift the bottom of the tab (to get it off the hook) while pulling the connector with fingers. Worked well for me.

Thanks Bob! I have 80K on my 2016 and will attempt this in the fall when it cools down. I was wondering if access to the PCV valve is easier with everything apart? I saw your PCV valve video and wanted to get your take on whether changing the PCV valve while changing the plugs would be easier. TY

[@GXBOB]

The plugs are on either side of the engine while the pcv is in the front. The common to parts that need to be taken off are minimal. But if you have a day to spare why not just knock out both regardless?

[@AgentJ415]

Uncle Bob has the answers 👍

Not always but I try.

[@mathspecialistsllc9519]

Thanks for the education. After reading the comments and watching the video. It would seem, that it would be better to start with the spark plugs that are near the firewall first. As one would be fresh and not tired after replacing the the other six. Would it be possible to list all the sockets, lenght of extensions, swivel sockets, etc.

[@doctorwgca]

I forgot to mention, you also need to push throttle open and clean BOTH sides and inside (to minimal extent....)...

[@kostovmail]

Just changed mine at 72k miles and they look pretty bad. Most were oily and looking pretty sad. Don’t wait beyond 60k miles. Same plugs are due for replacement at 60k miles in my Sienna. I used the most expensive plug available as of today : NGK Ruthenium. The engine sound improved immediately. Used 15 ft lbs torque for the plugs.

[@GXBOB]

Thanks for the input. I’ll try the Ruthenium next time.

[@doctorwgca]

The LAST electric plug that you snapped back into place goes to the Mass Airflow sensor.....unscrew it and use Mass Airflow Sensor cleaner....15 min to dry..... Throttle Body cleaner is separate, of course.... Also, 15 min to dry..... Clean throttle with lint-free rag/wipe after spraying and THEN 15 min to dry...

nope....i just have an arsenal of extensions and adaptors in my toolbox. You just have to use every single one until you find one that fits and swivels.

[@j-g9463]

Anyone know how long the coil packs last for? I’m thinking about changing mines. No major issues it’s just that I have a 2013 with 140K miles…figured it’s time for a tuneup.

The magic number is 120k miles per Lexus scheduled maintenance for spark plug replacement. If you’re going to do a tune up you might as well kill 2 birds with one stone.

[@jackmarr1776]

I had a hard time getting to the spark plug on the driver side because I couldn’t remove the fuse box and it was on the damn way...

The ones in the back are a bit tricky but u don’t need to remove the fusebox. Just disengage all the wire harnesses on top. I suggest you take a pic so you remember how to put it back

[@TN_HondaDad]

I did a dry run of sorts on the driver's side and how in the heck you pull the 2nd from the firewall coil pack out? A stiff tube with metal brackets is in the way?

[@GXBOB]

Hey Ron, I made this video many many moons ago when my editing skills were zero, my camera was crap. I have since earned my black belt in youtube angle shots so i'm going to redo this tutorial before this year is over. As far as your 2nd to the firewall coil pack, I loosened and zip tied the main wire harness out of the way. I used an angled mini pry bar to dislodge the plug from the coil. I used another plastic pry tool to dislodge the coil from its cavity. At this point you really have to go thru the real motions (instead of a dry run) to weasel yourself in different directions as the coil packs slides out. It doesn't come straight out as it seems, it does slide out at an angle from what i remember.

[@TN_HondaDad]

@@GXBOB Thx - If I had the spark plugs I literally could have changed 3 on the driver side. I just wanted to see about moving the harness back, then I unsnapped the first coil pack then said heck let me take it all the way out and before I knew it essentially did 3 of them. Learned a few tricks along the way with unsnapping those clips for the coil pack and a very small angle pick helped a lot and got easer as you learn the "trick" But yeah, the 2nd from the rear had meta "tube's" where it I couldn't get the coil all the way out but didn't continue on after my 5 min peak under the hood turned into nearly 45 min of tooling around. lol Appreciate the quick response and will see if I can move things around when I go replace for real and zip tie a few things. From your video, I feel if I do the driver side first, the passenger side will be easier too. Cheers!

[@tracyewatkins]

GX Bob thanks! What kinda fuel mileage are you making?

[@GXBOB]

Tbh, i never checked, never cared. The moment i decided to buy a GX, i threw all that out the window. Probably why i always fill up my gas at the closest convenient gas station instead of the cheaper one with a long line at the pump a mile away. I’m currently paying $5.14 a gallon at Chevron.

[@ericholt3199]

Why did you skip using dielectric grease as a best practice?

[@GXBOB]

Dielectric grease is to prevent misfires and allows for easy removal later on for your next plug change. Unlike many people, I do maintenance way before the manufacturer recommended intervals. I change my brakes, tires at 50% wear, full synthetic oil changes at 5k, air filters every other oil change. You get my drift. My parts don't stay on the car long enough to misfire or get stuck. These tutorials only help guide u on high level steps and short cuts and don't necessarily get down into the weeds. But if asked in the comments I'll most likely recommend greasing them especially with the 1st and 2nd gen GX. Great question though!

To be honest, i have always tightened it to a “snug” feel. Tight enough but not overly tight. Same as an oil filter. Book calls for around 13ft lbs but you have factors such as how crudded your threads are or if you’re using anti seize, etc…
