Hello,
I'm gathering parts for the 100k mile service and wanted to confirm if the GS350/GS460 share the same spark plugs? I called the dealer near me and they want $17.xx per spark plug. Amazon has a Denso one which I know is the OEM part, but not 100% certain if the one on Amazon is the same as the one that came from factory. I pulled the service history and the previous owner never replaced the spark plugs so it's a must item on my to-do list. If someone can confirm if the plugs listed on amazon are the correct part for my GS460, I would greatly appreciate it. Link shown below.

Thanks.

Not sure if itll be cheaper, but check rock auto as well. They usually have a 5% coupon code floating around thall usually cover shipping costs

 

Thanks. Price is basically the same at both vendors. I get free shipping with Amazon Prime.

 

I had the same question a month ago concerning cheap Amazon plugs. Price seemed too good to be true. When the vendor could not confirm where he purchased the plugs (he had a one time buy), I asked for a refund. He complied no problem. It's hard to know what's OEM and what's counter fit (or from China). Buy with caution. I don't have a link here, but look back through this forum and check out the link. I originally thought it was a great buy, but now I'm not so sure.
I haven't installed the plugs, but I did get a 100 % refund. I'll see if I can find the link.

Found the link...buyer beware with Amazon/Ebay purchases.

 

I purchased plugs (FK20HBR11 or 3473) for my 08 GS 350 from Amazon (prime) and as far as I could tell (based on everything in CL and everywhere else) they were genuine.

 

Rickdestick,

Those are the same ones I plan on buying. It appears that the Vendor is Denso...so I'm incline to assume they are OEM. I will go ahead and get them...Thanks.

 

MYLparts should have the oem plugs for the 460, use the club Lexus discount code CL5 when checking out to get a discount, usually cheaper than the dealer.

 

Becareful of fake oem looking spark plugs on ebay
