Celica Forums General Discussion General damnnnnn this is some shit

okay guys everyone with a used or new Celi please go check your spark plugs, i finally desided to get some, and i bought the OEM ones, sence everyone said there best for our cars. well i finally took the stock ones out and wow, there were fucking burned to the bone, i guess thats y i dynod so low on my gts, any how i had the wrong spark plugs in there anyway they were platinum ones. well everyeone please check yours, because it made a big difference, lift is stronger and a lot lauder
here are some pix

oh and by the way i only have 76,888 miles

only 76000 on a gts id say it would be about time to change em by then

what part do sparks play with our cars? Why are they needed exactly? Sorry, noob question I guess, lol

They make a spark that lights the gasoline pushing the shafty thingys and makin ur wheels spin! lol noob answer

yeah but the guy starting this thread got "better" ones right? How can one be better than another one????

Your old ones look ten times better than mine did b4 I changed them... Now I use BOSCH 4

U can get them from AutoZone..

will change my soon. i will go with bosch. or is there a better choice??

Just like your noob answer said, in your combustion engine your gas is ignited by the spark allowing your engine to power your car.

As far as your second question why one is better than the other. It has to do with the "quality" of spark, and the longevity of the plug itself. Let's say you were to use a non precious metal like tin to make the spark plug. The way a spark plug is designed the spark appears in the little gap. Well if that were made from tin it's safe to say the plug would melt pretty fast in such a high heat environment, rendering your plugs and your car useless pretty quick. SO we use other, more durable metals, like: gold, iridium, palladium, platinum, and yttrium. These "more exotic" metals can withstand MUCH higher temperatures meaning you have to change them less often, and they are less prone to gunky shitty buildup. Also they can produce more powerful sparks, basically iridium can make a better spark than tin can because it can withstand more heat and more electricity. As a result, overtime the heat and current running through the spark plug errodes the curved part at the top making it larger and larger till eventually the electricity can no longer be channeled to produce a spark. One can run higher voltage to overcome this probelem, but then they just increase the errosion rate. That's why one spark plug can be better than the other.

Does that answer your question??

^^ thanks

i added a few sentences at the end to let you know how a spark plug breaks down overtime

so are spark plugs DIY's or do i have to take it to the mechanic to get them changed? I see them on top of my engine where it says VVTL-i but im not sure exactly how to change them cause i haven't really looked into it. I know i need it cause i have hard crank and it takes like over 1 second of crank to start the car. Sometimes the remote start (my compustar alarm) failed and tried again cause the crank was too short. WEll i changed the remote start option so it's all good though.

I change mine myself. But if you don't feel comfortable doing it yourself take it to a mechanic. It's not complicated or anything. But it all depends on your comfort level with the job. Basically you remove the caps that are over them, use a rachet extender and a spark plug remover and crank em out and crank the new ones in. Not a big job but if your not careful stuff could go wrong.

are the bosch ones you talk about iridium?
I have 40k on mine and they still look brand new. no carbon build up or nothing.

the stock plugs are: DENSO Iridium.

do not get any other type of metal, if you want the best out of your car, Iridium is the way to go.

btw, i didnt know bosch had an iridium plug?

^^^^^^ yeah i read somewere to get just oem ones, the rest are crap. were are the pros in here, LUCKKKYYYYYYYYYYY!!!!!!!!!!!!!!!!!!!!!!!, BLUEEEEEEEEEEEEEEEEEEEEEEEE give us a solid answer

WTF are you using platinum plugs for ??????? those are NOT the OEM plugs.

If you're using anything other then iridium you're crazy.

that is all

denso is the shit

expensive as shit too

some FYI...

anyone know for sure what ones best on our cars?

Denso!

how much are the denso ones, i have a feeling if i go to toyota to get some new ones they gonna take me for all i got.

factory is iridium and the only good ones for us is iridium. anything else is only cause people try to be cheap.

I use iridium

Im going to check mine out right now... I'll take pictures..

All Done... Here is the pictures... from start to finish.

Examine your plugs.. Replace everything and Ur done... Not hard at all..

Isn't there a certain amount you're supposed to torque those plugs to?

I'm a big fan of HKS with all my previous cars, so I use HKS Iridium, haven't had a problem.

Excellent photos

I just wrote an install guide using the great photos you took... I hope this can help someone!
