one more question:

The service manual says to use anti-seize when installing new plugs but NGK says NOT to use anti seize. what do you do?

I might put a little dielectric grease on the connections with the spark plug and coils, but I've never used anti-seize. Never found the need.

Swapped out my plugs at 31k miles, tuned since 17k. I used to change them once a year on my tuned 10th gen. Didn't even realize how worn they were, but I'm glad I swapped them out. Throttle response is much better now; I don't have to go wot nearly as much.

You gapped them or no?

ordered some NGK 92411s from Rockauto today. they had the best prices. Also got a $5 TYC cabin air filter and a $11 Wix engine air filter. Beats paying $35 each for those filters from the dealer.

Spark plugs were $14.24 each. Local dealership wanted over $40 for each plug...

finally got around to changing the plugs and, wow, that was easy!

easier than changing the oil. you don't got to mess around with the front/center jack point, finagle the splashguard off, and try not to spill oil everywhere.

took a total of 15 minutes. Spark plug torque is 22 Nm (16 ft/lb) and the ignition coil bolts are 12 Nm (9 ft/lb).

plugs looks pretty good for 86k miles. no noticeable increased gap, from what i could tell.
