spark plug type

[jim49]

Hi I,m a forigen car guy and use ngk or bosh plugs my daughter has a 2002 alero with a 4 cyl motor was going to put ngks in it but was told to use only ac delco plugs in it they want 10.00 a plug for the delcos and 4.50 for good platium ngks what do you alero owners use i thought ngks are a better plug but will go with what you guys think Thanks in advance jim

[Vinalero]

10 bucks a piece for Delcos? you are being robbed I believe.

[01silveralero]

Bosch-Platinum+2 / Spark Plug 4304 are only 4.99 a piece
ngk v-power are only 2.09 a piece

i would just go with bosch platinums+2 also dont regap them (only if u get the bosch plat.+2)

[Oldsman]

bosh plat +2 work great

[Redog]

I had no luck with the Bosch +4's don't get them

[cherrington17]

i was recently inside an autozone, and they had plugs on the counter. your standard, then some idirium(sp?) then another type of some metal i've never heard of, with 4 prongs, instead of 1.

do they actually do ANYTHING more then standard ones? i didn't bother looking at price, just wondered. and i know asking the sales guys, will yield the standard answer....

its my understanding that electicity takes the path of least resistance, so regardless, only one electrode would work, regularly. ... so whats the point?

[SIUlero]

The other metal is Yttrium...I have no idea what it is, but they claim it lasts longer than anything out there, and it's actually mixed in on the Iridium Fusion, Platinum+4, and Platinum-2 plugs. You're right on electricity taking the path of least resistance...the advantage is supposed to be that since the electrodes actually wear down over time opening the gap, there's now more electrodes for it to wear down, so they last longer. Other than that, the only advantage I can see with the 2 or 4 electrode plugs is a more exposed spark that should promote faster fuel burn. That's why I just went with Platinum-2's for my current set.

[jayson_waltz]

i had absolutely no luck with bosch. Delco's would be just fine, but if you just don't want them get the NGK iridiums. I put a new set in my sled, again this year and it stopped all its top end sputtering. they work nice.

I have the Bosh Platinum 2's in my 2.4 and they work very well.

NGK is goodtimes.

since we are on the topic witch plug and wire combo works the best?

[Vinman]

i believe carquest has the ac delcos for about 2 dollars or less per plug...right now i have the delco's and the o.e replacement carquest wires....and yes i am a fan of carquest...they use quality products for thier "cheapos"..for ex. their filters are made by wix-used in nascar, their oil- valvoline, suspension parts are made by moog- used in nascar...etc..

I can't remember who makes their wires- but all i know is that my combo gave my ho a lil more power (then again im sure the person who owned this before me never even touched the rear plugs)

[YALEROYNOT]

130,000 miles (owned since 36000)
think i should change mine ?

yea i think so....should have happened atleast once in between

[lonnie]

I put Champions in mine, and have yet to have a problem. They were gapped a .050 when I got them out of the box to so I didn't bother re gapping either. Everyone makes a big fuss about get this one or get that one but really it all depends on how much you are willing to spend and whether or not you have a performance setup or not. If so...go with the higher cost plugs if not then anything you buy will work. Just make sure it's gapped right and installed properly if doing the work yourself. With all that said the balls in your court.

[pawzbear]

wow at 130k on stock plugs? should have changed at maybe 75k at the latest.... to prevent arcing and ruining the coil pack like mine did at about 90k


anyways NGK is fine on most imports.. is actually factory recomended or whatev. But not on our aleros. they dont seem to take to them very well. Stick with Bosch it is a quality product.

The Bosch OE style is 1.99 our cost 5.20 list
Bosch Platinum plus (the fixed gap one) is 5.45 our cost 13.80 list

Thats a general price range to expect (on list) They shouldnt be much more marked up than that! crazehh

Either plug will work very well i recommend sticking with the regular OE one, more isnt that necessary

[alerored04]

stay away from bosch +4's though. i have heard nothing but bad things about them. My autolites have kept me happy. Performance plugs and wires are a joke unless you are pushing rediculous amounts of power and have the rest of your ignition system upgraded. Otherwise it is just a gimmick.

I think your opinion that NGK are only fine on imports and not very good on N-bodies is false. I have proof that they are as good if not better.

so do you take paypal ? how about wires ? price shipped to 19438 harleysville pa ?


the paws aleromod speed shop !!!! what yall think we get a discount and she pockets some cash. Im for it !!!!

[pawzbear]

i dont sell them lol i was talking about how much they cost us as opposed to customers buying retail...

just to say about what the prices SHOULD be at.


And spyhunter i was just saying that based on other's problematic experiences with NGK in aleros.
... And that i know they are factory recommended in many imports.
I have never put NGK's in my alero, personally.

[GA_turbo]

NGK TR6 in my turbo grand am 1.69 each i love them, autolites on my cavalier 2.4 and denso copper on my 2.2 ohc sunfire.

NGK and autolite FTW.

[meadus101]

plugs are probably a good idea for my Ho,

As i've had it for 10k and it was a corporate car, but i don't see anything about the plugs and wires on it. So yea... I want easy to put in, None of this gapping Crap. I do like NGK, they've always been great. And i don't have alot of car shops here in town.

1. What gap do i need.
2. Prices on Delco?
3. Sorry for the Thread Highjack, But it is filling it all up with Info.

Most people's problems around here regarding the ignition tend to not be spark plug related. THen when they change the plugs they still have the issue they still blame the plugs. People forget, especially on higher mileage the stupid coil packs that are crammed inbetween the cam towers can fatigue over time through the heating and cooling cycle of the engine *plus as mentioned being stuck between the cam towers where there is a lot of heat produced*, which can cause errating spark and other ignition related misfiring sort of issues.

The coil pack placement on these cars is the stupidest thing that GM has done, however there is a remedy.

Yep ... that is just about the worse place for the coils to be mounted. So, move the coils and add normal type spark plug wires. I may do this soon.

[Vinalero]

I heard those coil in the engine cover are expensive to replace, how much are they?

Anywhere from $200-350

[NoSweat83]

I have had no problems with either set of my NGK's. Good plugs!

[cherrington17]

what would your car do if the plugs/coils were bad? (stupid ques, but does the 3.4 have coil packs?)

mine seems to have really hard starts lately, and i can't seem to figure out why...

[spyhunter]

if they crapped out totally, your car wouldn't start. if they were starting to fatigue and die, your car would start with more difficulty.

however if your car is starting with difficulty, it could mean the battery, starter, alternator, plugs, fuel pump, fuel injectors, etc.....

yes you have coils on your 3.4.... 3 of them... look where your spark plug wires go to... Those fancy things they lead to from the engine are your ignition coils... the 2.4 has fancy ones of a funky configuration.

[cherrington17]

I know it wouldn't start... i'm not THAT bad w/ engines. :lol:

well... my battery has been reading at high 10-11.5V lately, but i'm guessing thats due to the colder weather. Alt is new, starter still clicks fine... hmm. i guess i'm checking plugs next since its easy.

I checked the front 3 (since its like 30 degrees outside) and they were perfectly clean. :glare: dammit.
