40k miles spark plug service pic

[n118nw]

Technically 40,500 miles but it's not like that 500 is going to make much of a difference. These things are so easy to replace. To my naked eye it almost looks like some might be a fraction of a millimeter off but it could also be my eyes playing tricks since the electrode gap is so small and I'm fairly confident the mixture is running normal--though not sure what it's supposed to be. I don't know if anyone's hooked up an afr guage. I had one from my Subaru days but I'm not interested in installing it since I'll never have a tune. I just wish Toyota would let NGK sell these separately because at $30 each, they're 3 times more expensive than the NGK Iridums were on my old Legacy GT (granted these were far easier to replace).

For those wondering, the plugs are part# 90919-A1008, I purchased mine at a local dealership for $29 each. You will need a 14mm deep socket (spark plug socket recommended so you don't have to pull them out with a magnet).

Still around 5k from doing mine, but I went ahead and snagged all 4 for $87 during the 25% discount.

Yes, refer to maintenance schedule.

40k is for the emissions warranty

In the owners manual there’s a maintenance and care section.
There are also separate warranty booklets.

Edired to show the page screenshot and link to online booklet…Enjoy!
