60,000 mile Spark Plug Replacement
 

How many of you have had the 60,000 spark plug replacement done and, what did it cost you (as a breakout item on the 60,000 maintenance list). Do you know if they had to pull the inlet plenum, etc. to get at the back row? Just curious as my 60,000 is coming up fast...later this summer I expect. TIA

Yes, you do have to remove the plenum. Very doable for the DIYer.

Is that merely for the emissions warranty? Presumably so. The iridium plugs will be barely worn at 60K miles.

That's weird right? Would be fine to push it to 100k miles minimum

60K miles is silly. I don't plan on changing mine till after 100K. This is a video I have saved for when it's time.

First, thanks to everyone for their inputs. I was not planning on slavishly following the manual's schedule but when I found that virtually every "expert" channel on the newer engine recommended the 60,000 mile change I thought I'd better check into it. The '14 that I traded in had a book schedule of 120,000 miles and it was at 120,000 when I traded and had not been done yet (and was giving no indications that it was needed). I won't be changing the plugs until I see a drop in performance/economy and then I'll likely pull a couple of plugs from the front bank to inspect first. I got close to 150,000 miles on the factory plugs on my old '04 Camry (4 cylinder) and even then the mechanic said I didn't really need to change them so I know they last a long time. I just figured better to be forewarned with info as to "when" and "how much" and find out what actual owners have experienced.

I know that the Gen 7 changed the game from 120,000 miles to 60,000 miles....not sure why but possibly due to direct injection? Strange since the 2GR-FKS on the Gen 7 uses both direct and port injection so I'd guess the port injection helps delay the carbon buildup on the valves and the plugs(?). The comment about the emissions warrantee is, I think, appropriate; Toyota is going to "cover their axx" with regards to that. However, since this is second hand and some distance from the original dealership, plus being in Canada and notably in "oil country" Alberta, emissions warrantees aren't exactly micromanaged!

When I traded in my 17 RX 450h It had 100,000 miles on it. my Lexus dealership after 60,000 mi kept asking me do I want to change my spark plug It's due. When I inquired about it I found out that it is to maintain the emissions warranty. I could care less about the emissions warranty. People posted on here that have had 2017 18 19 RX's that change the plugs at 120,000 mi on the plugs and they looked brand new.

Another money grab.

No kidding. In Canada, $200 for the plugs and another $200 for labour at a Toyota dealership. Coolant flush and change, $215. Brake fluid change $175. Just a second while I get my independent mechanic on the phone. :D (Before commenting, multiply those numbers by 0.7 to get $US)

I replaced the spark plugs in my 2007 ES 350 in August 2024. I did not take off the plenum. I used a mirror to see behind the engine. It took me 20 hours to get the back 3 done. I should have just taken off the plenum, I just really didn't want to. Now I'm looking at possibly replacing the rear valve cover gasket which requires removing the plenum. Not looking forward to that job.

Just a reminder when you do the plenum pull tape up the intake holes as soon as the plenum is off other wise Oh! 💩. Ever hear of the black hole when objects fall from you, there are lots of missing socks there?

Are you a dentist? 😉

I agree the plugs in these engines last a lot more than 60k. When 60k rolls around I will pull an easy up front one and inspect and like in past engines they can go much further, so I will not do the 60k DIY if I have the car that long?

With the previous gen, you did not need to pull the plenum. On this gen you either do that, or apparently, pull the inlet cowl and wipers to get at the rear bank. Different design from older generations.

Great for previous gen, for 7th gen we have the 2 options.
