I have a 2010 IS350c with 120,000 miles and it’s about time to replace the spark plugs, but if you’re going to do that, you might as well replace the ignition coils, right?

Has anyone used these? It’s almost too good to be true, so I have to ask you guys.

The pretty girl- I love this car so much

If the price is far below the MSRP then it's too good to be true. Toyota/Lexus OEM parts will outlast any third party

Thank you, that’s what I figured. I just had to check my sanity before I did something dumb. Do you think I should bother replacing them? I have no misfires or codes, just the mileage. I was thinking if I’m removing those anyway, might as well replace them. Is this erroneous thinking?

I definitely wouldn't chuck 120k Denso parts for some nameless brand junk unless you like walking. Same with plugs.

As you reach 200k, you might budget for them or buy when on sale.

Don't forget to clean the MAF, do the Trans and rear Diff too.

RockAuto sells legit Denso spark plugs. If the car doesn’t misfire, no need to waste money on new coils.

Thank you. I’m at the point where I’m ready to start fixing the little things and upgrading. LED interior lights, maybe upgrading the headlights and tail lights, I definitely need to address the convertible top switch, as it sometimes works and sometimes doesn’t. I saw something a few years ago on YouTube that is a suspension upgrade, a bushing replacement I think, that tightens the chassis feel. It has clear bras that need to be removed and replaced, and the upholstery needs to be repaired. All cosmetic things or small jobs, so I want to keep the engine running like a champ. Is there anything else I could do at this mileage to achieve that?

Definitely fresh fluids: Transmission, Differential, Coolant.

Afternoon, all.
Bought an '07 IS350 for my college freshman daughter w/190K miles 8/2023.
It's been throwing codes (CEL.VSC, traction control) and I've handled them in stride.
Replaced the MAS today (BG Induction cleaning wasn't enough) and thought about replacing plugs.
Can I use NGK Rutheniums or do only Denso/Toyota work w/o issue?
TIA!

I would stick with the OEM ones. I just replaced them all, used Denso Iridium from Advance Auto, 6 for 124$. I am pretty sure you can get them way cheaper from online Lexus dealers. You do not need to remove the intake manifold.
