Wise ass newbie

celicas come stock with iridium plugs, they are the best grade available, i just replaced mine with NGK iridiums, i think i paid like $30.00 shipped on sparkplugs.com,hope this helps

chill little man...

lol...talk about PMSing...

lol...

I need to replace my plugs soon too. I think you replace em at 60k im only at 42k

^^^ yeah, I'm with caliGTS...I'm gonna replace them at 60,000 too...as well as the clutch and flywheel, and the suspension if I don't do it before then

Well actually your supposed to change plugs almost as frequent as oil, like once every two to three oil changes, which is roughly once/twice a year, to make sure your plugs are at optimum level. The iridium plugs are stronger and more expensive so I think maybe once a year is good, 60k miles is way too long.
As for plugs, NGK and Denso are the prefered iridium plugs, The NGK are a bit cheaper, but if you really have money to spend you can get some Blitz, HKS, or Greddy iridium plugs but they are really,really expensive, and since they are manufactured by NGK and Denso anyway i dont think it really matters unless you have a full blown race engine.
The plugs aren't gonna make a huge difference in hp, but its better then nothing.

are you sure , because that would mean for me i would need to change every month and a half and i usually changed at like 60k too

really?!?!^^ Im going to change em ASAP in that case

spark plugs can improve hp??

^^ This is not correct, every two or three oil changes is about only 9,000 miles considering you change your oil every 3,000 miles. Spark plugs usually last around 30,000 miles or more, so unless you know theres a problem, you really don't need to change them that often, or you are just wasting your money.

Also if you use Platinum Tipped Plugs, they last longer than the regular kind. Somtimes up to 100,000 miles.

And about which plugs will give the most horsepower? Just go to the dealer and buy whatever the car was first equipped with.

A spark plug isnt going to give you anymore horsepower.

from my understanding, spark plugs doesn't really gain any hp, instead it can restore some lost power due to the aging of the car...

We've had a few new idiots around the last few days.
Somewhat entertaining. His sig says "face it, celicas are ugly"

I doubt he's here to learn or help anyone

Anyway, I change mine approx every 50,000 KMS.(canadian)

I change mine every 3 months or 4 times per year.

I also change my oil every 2K miles

you should only use irridium plugs.

Get TRD Japan Iridium Spark Plugs

don't waste your money.

The Denso Iridium tips that come stock are the best you can get for our engine.

dousch-bag

If you go to a Toyota dealership, they will tell you that you don't need to change out the Iridium plugs until around 90k miles...

...that being said, I changed it out at 60k.

I bet you noticed the gains with the new plugs? I did when I changed mine at about 65,000 miles.

ye... and i believe TRD Japan Iridium plugs are from DENSO also.

(strickly for GTS users only. if you have a GT and you do this, you will loose HP and ruin ur engine.)if you rev ur engine like crazy everyday, redline it everyday. get a new set of plug that is one class colder than ur stock ones. from IK20-IK22 or IK22-IK24(DENSO) i forgot what our stock plugs come with.

I'm not for sure but I think the Celicas come stock with 100,000 mile spark plugs. I have about 50k Miles on mine and the plugs look only about half way worn down.

i put the denso's in my Teg GS-R and i noticed, when i get some more cash to blow im going to get some for da celi

^^^celi comes stock with denso iridium...

change them when you need, dont change them as they are a mod. cos wut you will do is just swap out a totally same spark plug...with the old one performs just as good as the new one...
