So i want to change my spark plugs i'm at 62KM or 40~K miles.

it might be a bit early but w/e i don't mind wrenching

this is strictly for N/A daily driving should i get hotter plugs?
i assume i should stick with plat tips right?

thanks in advance.

 

i think a lot of people here use the NGK iridiums

but stay at stock heat level if you're staying NA

i think the stock plugs are supposedly good until 105K miles

 

I just changed mine at 50,000 miles with these:

Hard to beat the price, and shipping was quick. My old plugs were probably good for more miles, but I am planning on getting a tune, and UpRev suggested I replace the plugs before that. A lot of us use the iridiums and haven't heard one complaint. Took me an hour start to finish. Kind of a pain in the butt, but saved a lot of money doing it myself.
