MY 60K service is coming up and I need to replace the spark plugs. A friend recommended NGK. Are these spark plugs high quality? Is this the correct part number? (Will either one work?) @bclexus NGK Spark Plugs
I would buy OEM plugs from the dealer and unless performance has suffered wait to change out.
This will prevent purchasing counterfeits and buying incorrect plug as various GS years and trims have different part numbers based on the gap requirement.
Can be found online at Bell Lexus for less than $15 each during their promotions. Bell Lexus
These Iridium plugs last well over 100K miles on these cars.
Agreed, buy the OEM...not the equivalent Denso or NGK part but the OEM part number.
It probably doesn't matter but it's such an important part of the car, easier to just buy the one specified in the manual. I bought mine from a Toyota dealer, much cheaper for the same thing.
Go aftermarket if you wish but I find piece of mind when doing what the manual suggests is acceptable. Not just spark plugs but when it comes to acceptable petrol, oil, transmission servicing, filters etc. The only times I stray are for cabin filters and diff oil viscosity. Q
Toyota spark plugs are made from denso spark plugs from what I have read online (sometimes NGK I have read also), but NGK offers higher performance compared to denso. I work at an autoparts store and no matter who I talk to whether it be the 70s ford guys or brand new car lovers, everyone says NGK spark plugs are the best. If you want, dealer ones will always be exactly how you got the car. Whether that means it offers higher performance compared to NGK is always up for debate, but from what I have heard and seen. NGK is the best option. Now the NGK number should be the ones you chose, idk if they change in the different years but that should work

This is correct, but which Denso spark plug is the correct replacement for 9091901249? IKBH20TT or VFKBH20? IKBH20TT is the official answer but they're one fifth the cost of the genuine ones (which never had an aftermarket Denso part no AFAIK) even when bought online which doesn't sit well.
The TT breaks their own part number convention (their own website indicates it shouldn't be a long life plug based on the part no) but Denso Australia conceded the mixup but assured me it's a long life plug.
I'm sure they're fine and you won't notice the difference but one cannot help but wonder why one shouldn't stick with the plug Denso developed specifically for the GR/UR family.

In the context of a 2GR motor, how does it offer higher performance? Is it not like saying Michelin are better than Bridgestone? They both make high and low performance products suitable for different applications.
Every week someone is asking 'how can I make my stock GS go faster', I'm yet to see somebody answer 'change over to NGK spark plugs for more power!'
I agree with you, I meant durability and not performance my bad. It is true on what people prefer to what they do but for everyday use NGK is what most people prefer is what I meant.
Purchasing a spark plug from the dealer makes no sense. Pull a plug from your car if you want to prove it to yourself, but it will say Denso and if you had purchased the “Lexus” plugs, you’ll be spending a lot more money for the EXACT same thing.
Denso is the real deal. No need to look elsewhere. I find RockAuto’s pricing to be more than fair, and they offer our forum an extra 5% off. I’d go that route.

9091901249 is the Denso FK20HBR11, the plug for my car. Unless I'm buying the FK20HBR11 I'm not getting the EXACT same thing, their current range of plugs have completely different numbers. I admit my opinion is coloured by the fact that I can't buy it from local parts stores anymore as its manufacture is discontinued, only dealers stock them in my country.
I'm not suggesting aftermarket plugs nor the current discounted Denso plugs aren't suitable and my reasoning is in a previous post.
Correct Spark Plugs?
