I tried searching and I can't seem to find a thread on it. I'm at about 116k on my ES300h so I want to go ahead and do plugs. It seems like there are a ton of iridium options and even several different iridium denso plugs. Is there a part number that is optimal for replacing the plugs in these cars?

Thank you in advance!

 

I ordered DENSO 3484 {#9091901259, FK16HRA8} Iridium Long Life; Super Ignition Plug (SIP) Gap .032

Are these the optimal plug?

 

This is plugs I was using and still using on my hybrid .

I have order over ebuy and price was better than thrue dealer.

Same as OEM plug.

And always make sure it's a DENSO plug not some generic name.because you have to make sure that those spark plugs have correct heat range.Some of them are design for highway and some of them are for city .Cold And Hot range.

 

Beside that I was told by Lexus technicians replacement of those plugs must be after 200 000km.Looks like they last long time.

 

Thank you, man! That part number matches up with the spark plug I bought. You can see the FK16HRA8 written on your box is also associated with the Denso 3484 Spark Plug. I managed to get them on Rock Auto for just under $10 each. Shipping was a bit hefty though. All told it was like $51 or 52 shipped for the set. I can't seem to find a better price than that. Not sure how good that is, but it seems about comparable to everything else I have been able to find.

 

hey i know this is not the exact topic of this post but since it is on spark plugs and I'm probably about 2 or 3 months away from having to have them done myself due to miles
im planing on going to Lexus for them I know someone once said and I have read that the hybrid is pretty easy to do the 4 plugs but since I am handicap and due to back and leg issues i just cant be on my feed long and bending over the hood not easy for me even when just to check all the fluids i get hurting and need to take a break i wash my car on my own and spend about 2 hours doing the outside. so I'm just going to have Lexus do it
how much should i expect the dealership to charge me to do the plugs on the hybrid 4 cylinder ?
