I have a 2003 2.2 Cavalier with 55,000 Miles on it. I want to put the Bosch Platinum 4 Spark Plugs in my car. First, Where are the plugs located, and Second, are these plugs good for my Car. This car is going to have 200,000 on it before it is paid off.
1)... i am not sure..
2) Those are garbage.. stick with AC delco or go with NGK's.
.........holy @!#$ you have high miles....
..... i have a 99 and its got 57,220 miles on it...
mine is an 02 w/ 50k on it
but yeah, ive heard nothing but bad things about the bosch plat +4 in our cars

don't know about the +4's but i went with the NGK platinum, your plugs are located under the black piece of plastic that says ecotec on top of your valve cover
After 25K+ miles on my 1996 2.2L OHV they are still working excellent. Fast starts, clean burn, smooth idle.

1) ecotec - under the plastic
2) the bosch +4's work great for me; but if your going to go nirous or boost get the NGK's

I just want to save gas mileage. No NOS. I drive 50 miles one way to work 5 days a week. That is all. Just want to save money on Gas and Long Term problems.
something that has def helped me and my girfriend save on gas was the denso iridium. might not warrant the price for you, but heres some reading to read up on...

iridium is definately not needed, but the smaller the electrode, the less energy required for combustion, better the spark, the more complete the burn, the better the gas economy.
my first set lasted 50,000 miles, i did reg maintainence on em, regapped when needed. on the second set now with roughly 10,000 miles.
and i do reg maintainence, sometimes earlier than needed. like oil etc.
bosch plugs are fine, a spark plug is a spark plug. the +4 have a better chance of firing all the time, unlike the generic crap like ac delco!!!
honda's are like tampons.......
EVERY PU$$Y'S GOT ONE!!!!!
keep the delcos (although i had no problem with +4s, but some have)
change your fuel filter when needed
keep the top end clean
DON'T drive it like you stole it
keep track of your mpg for indicators that something is awry(don't worry aboot small shifts but keep your eye out for "alarming" trends)
keep your tires properly inflated
read the
"tips to save on gas" FAQ to figure out what's missing
i have aboot the same commute, damned construction is killing my time though
I should change them at 60,000 though, right?

a spark plug is NOT a sparkplug. sure they all do the same thing, but some are way more efficient than the other.
technically speaking, you shouldnt need 4 prongs for a spark plug. electricity always takes the shortest path. so really only one of the prongs is being used for the majority of the time.
ac delco is actually decent as opposed to a gimmick plug with more prongs than needed
Todd, you change em whenever needed.
how do you know when you need to?

and since event posted the first time while i was hunt and pecking
listen to him, he is a wealth of information
listen to james as well, all that he just posted are also GREAT info, that many let run by em. especially on tire inflation.
once again ill have to disagree on Denso being a quality product, I noticed no increase of any sort over stock, after 30k (changing oil every 3000-3500 miles) changed fuel filter, injector cleaner about every 10k, most of the plug is worn away, not to mention the fact that the denso is a shorter plug
Go with the proper AC Delco plug for your car if you feel the need to replace them 41-981 is the part number

sorry but i MUST disagree with your view on denso.
considering your maintainence is off and for the past few months you have been wanting to change you water pump and head gasket cause you said you have been running warm... if theres a prob, not sure if you have corrected it even yet.....
then to top off you;ve had a powersteering noise, and i said check the fluid 2 months ago and OFFERED to check it FOR YOU at denny's before we left! you said you would check it the next day....
and you just had it checked... and the noise turned out to be LOW FLUID... 2 months later.
seems your maintainence lacks a bit. you also said you let your car go up to 5000 miles before as well. thats def over 3500.
and denso sells plugs of the stock length if you even did your research matt. matter of fact the guy in the boost forum posted the part number. you might have missed it, but dont ignore the facts.
and lastly i;d like to point out that you lied either here in this post or your other post on DENSO.
here you just said.

Q. How long will Iridium Last?
A. Iridium use represents the most significant technological advance in automotive spark plug manufacturing, since platinum was introduced in the early eighties. As vehicle manufacturers produce increasingly complex and efficient automobiles, there is a greater need for long-life plugs that can tolerate leaner fuel mixtures and improved combustion processes. DENSO has responded to this need by developing its Iridium alloy, originally for OE applications. For example, many newer Lexus’ and Toyota models carry an ultra long-life Iridium plug variation (.7mm with platinum tipped ground) that is capable of up to 120,000 miles of service. DENSO Iridium Power plugs, with their .4mm center electrode, have been developed for performance applications. Because gradual wear will “round-off” firing points over time, the concentrated firing power and voltage requirement benefits will be reduced. For this reason, DENSO advises replacement after 30,000 miles.

also i asked in your other post that you post a close up of the plugs you said you have. you never did as of yet. it would be easier to see what your problem was on why the plug allegedly failed you.
heres mine after 50, 834 miles

and thats WITH running an MSD dis 2 through it.

WRONG, The waterpump was thought to be faulty in OCt it was replaced in Feb found to be NOT faulty, theres nothing wrong with the Headgasket at all, I will have to change it when I get a ported head what you think im going to use the old one? BTW dont get the idea that my maintance is off the power steering fluid has anything to do with the motor cause it doesnt I thought even you would be smart enough to realize that.

WRONG AGAIN I had stock plugs in to 27k Prior to the 03 Bash I put in a set of Densos, at around 50k I was having fuel system problems and replaced everything including the plugs, I replaced them at High Rev this weekend with 70k on the car Im sure you can do basic math but that means about 20k on each set of Densos
Also in my other post I just did post pics and they look nothing like that through a STOCK ignition system

um it shows that YOU DO NOT do maintainence regularly. maintainence is checking your fluids, knowing when to add them and why they went away. it was 2 months before you checked. granted i know women who know how to check their fluids in the car before a problem starts. and when they do hear a problem, they check it.
the power steering pump is apart of the motor, it runs off your cam shaft, off of my serpentine belt. so since its constantly running it is an accesory of the engine.
man up to the fact that you not checking it when i offered to, and you drove around for over 2 months like that, was a piss poor job of YOU doing maintainence on your car.

ok 20k per set of densos.... sorry if one cant read super run on sentences. thats what the periods are for, so i know when to stop one complete thought.

it reads as if you are saying after 30k of use.

yup thats your picture.
here are my additional 2

like said matt, maintainence is more than just checking fluids or looking to see if things appear ok. sparkplugs need to be regapped over time when they wear down. i check mine every other oil change if not EVERY oil change. else you get too large a gap and thats when things run awry. with that much gunk or burnt area around the top of the plug where it says DENSO, i can see you did virtiually NO maintainence whatsoever. if thats burnt, from carbon, that means your plugs were NOT torqued correctly and combustion CAN leak out.
also on plug size, in the boost forum someone posted the "propper" plug part number. you can get plugs in a variety of heat ranges so size of the insulator shouldnt be a problem. the washers that come with em can be added or subtracted to be the same size as the ac delcos. but i am sure if you knew that you wouldnt be saying half the stuff you have thus far.
like i said in the boost forum about not doing your homework on these, like you did with the ebay coilovers you bought and thought they were ground controls just because someone changed the collar (even though blue springs didnt throw a red flag) either situation....you didnt research, or you didnt do your maintainence as you think...

Ok, I will go with the delcos. i read that iridums fire too hot for the ecotech. Is this true?
I will never buy another denso plug of any length, they are overpriced junk, I can buy a set of 4 ac delcos that run cooler and cost as much as 2 densos not to mention they last far longer

not really true... just true for those who dont do their homework and buy the correct plug. or those that just plain out do LITTLE maintainence for their car.
basically "an iridium firing to hot" is another one of those myths, like when you hear people say "you need alot of backpressure for an engine to work right"
with boost irridium is a no no
1989 Turbo Trans Am #82, 2007 Cobalt SS G85
No boost here. Just a stock cavalier that I drive A LOT! If I am going to replace em, I want to do it right. You guys have been great help.
