What exactly is this post :blink: :huh:

10 HP for plugs, yeah right :bs: :whistle:

[kniedelm9490]

i thought as much im just googling random stuff and thinking its funnythat they are guarenteing 10 hp

[cliffordwoeller]

I have NGK laser double Platinum spark plugs so did I waste my money ?

[kniedelm9490]

well i just googled them and they're ranging from like 11 bucks to 100+ how much did u pay?

[cliffordwoeller]

about 10-15 a plug have 2.4 engine

[Redog]

When I was young and stupid I put the Bosch Platiuum +4's in my Alero. It ran about the same and started maybe a split second quicker, but it started misfiring really bad. I almost traded the car in of a GTO in Dec 04 becuase nobody could figure out what was wrong.

I bough the ACDelcos and it runs the same.

In fact I bought the wrong plugs for the Delta with the engine swap. (ACdelco R43S and I should have gotten R45S) They are just standard plugs for $2 a plug. I bought the ones for a 1968 455 motor, not the 1968 350 motor. I bough the right plugs, swapped them and the car ran a hell of a lot better. The motor started making that struggling noise when I got on it.

MPG is better with the new plugs too, from 9 mpg to 13 mpg :eek:

[cliffordwoeller]

well i am still trying to figure out if i had just wasted money

[Jferg2223]

i have the plugs for my 3.4 i have noticed a difference in gas mileage the main difference is the fact that they are guaranteed for 100,000 miles so if one fails under normal circumstances they send you a whole set. And Bosch sucks so never ever put them in your car it took me three sets of bosch platinums in my probe to get a whole set that would fire right. in my opinion its not a waste of money, its the reliability issue with me but i can say its made a difference so if mpg goes up it proves its definately a more efficient spark.

[cliffordwoeller]

i have the 2.4 engine and i get about 200 miles to a tank and i cant figure out why i am getting such crappy gas mileage

[YALEROYNOT]

I just put autolite plugs in from milizy and work great. $15 for 6 plugs along with taylor wires. I replaced the stock plugs at 136,000 miles fancy plugs are a waste. delco or equilant is all you need.

i put thos split fire junk in my jet ski and after fighting with it for half aday to get it running right (and not winning) the plugs took a swim in the lake and the old ngks went back in.

I get better mileage from my Cherokee! Well, close to it, at least. That's still horrible though!

[Naich]

Having new spark plugs and wires will restore lost performance and pickup, but any spark plug maker saying they will give you 10 HP is just marketing. You won't get that over stock performance. Maybe over used 80,000 mile plugs.

[cliffordwoeller]

well i bought taylor wires only to discover i didnt actually have wires but instead like a boot that sits over the spark plugs is it better to change to wires?

[Trickyslick]

Wow I would do some major checking & replacing of parts I get around 330 to 350 a tank, 2.2 auto.

[jayson_waltz]

200 miles a tank in town sounds about like mine. i get about 18-20 mpg.

and paying $100 for spark plugs is just stupid. I got 4 for my car for about $25. That is the price mechanics or employees pay but still they shouldn"t be much more than that.

[kniedelm9490]

i get like 17-18 mpg with a heavy foot so idk

[Vinalero]

I used to get 360-380 km per tank (230 miles) last year.

But for some reasons, I get around 470-480 now (300 miles) with only putting 40psi in the tires like some guys told me on here.

I even made 520 km (325)on one tank one time I was being really careful about my mpg (50% highway + 50% city)

[kniedelm9490]

dam mabye if switched back to the stock 16's id do alot better

[YALEROYNOT]

i get 340-355 miles a tank with my 3.4

[kniedelm9490]

i get 340-355 miles a tank with my 3.4

ok so i have a problem some where ... because of the fuel issue ...so I have replaced my spark plugs which I paid at most i think 50 for a whole set... I have put a k&n airt filter in change my oil religiously,and oil filter have changed my fuel filter, hmmm what else do i need to look at to possibily fix this gas issue ?

[negolien]

I got a 2001 gls sedan with 50s stock of course and stock plugs and I get alomst 21 in mostly cummuter driving ie 15 mins of normal in town and 20 mins of bumper to bumper surface street traffic /shrug.

[kniedelm9490]

the tank is like 14 gallons but i swear ive never filled up past like 12.5 and the light is on E.. so idk

Well what kind of driving do you do? I used to get 18 to 20 MPG all city and I filled up and always put in between 9.5 and 11 gallons, so there is your 200, now I'm getting 19 to 21 combined city and highway since I moved to the burbs. I've been babying it the past 2 tanks and I got 21.4 and 21.6, I'm babying the 3rd right now and I have just over 1/2 tank (probably about 6 gallons empty) and I put 150 miles on the tank. That's appox 25 mpg, if I'm right. That includes a road race today and 80 on the NJ turnpike just to keep up with traffic.

With the K&N, at 65 I'm under 2000 RPMs ;)

[cliffordwoeller]

hmmm well i have been a pretty radical driver but since my first car show last week and joining this site I have calmed down cause I have realized how stupid I look especially since I am 26 and doing it so this tank i have right now is the first tank I have been for the most part a normal driver although I have caught my self doing quick accelerations which I am trying to break that habit now

[Cliff8928]

Ya, stop the hole-shots all over the place. My Alero (ecotec) can easily get at least 300/tank (usually 25 MPG) in town and i can get over 400 on the hwy.

If I drive the crap off my 3400 around town I have gotten it down to like 14 MPG or something like that (maybe less, I usually don't track that one)

[cliffordwoeller]

hmmm ok so would my 2.4 having near 130,000 miles be part of the problem ? and at that many miles what should I be replacing inspecting,or changing ?

[kniedelm9490]

ya at this point the most i get from a tank with driving like a nut is like 225 so idk its a hard habbit to get rid of

[cliffordwoeller]

isnt that the damn truth even though I know all i am doing is shaving a few seconds at the most off of my time to my destination

[kniedelm9490]

yup itryed driving slower tonight but more ppl kepted riding azz

[WhiteV6]

Iridium plugs have less resistance, so its like throwing a hotter coil on your motor. This is why they claim 10hp, for those with weak ignitions. They are also self cleaning and last a long time. Is it worth the money? In the long run, yes. Double laser platinum? I dunno what that means but I wouldn't use platinum plugs, or anything that says bosch on my vehicle.

[cliffordwoeller]

well mine arent bosh and from the sounds of it bosh isnt that good

[Redog]

^^ Please type in English

[cliffordwoeller]

lol it was english I was just a lil or a lot sleep deprived lol

mabye ill look into it but it seems alittle expensive for what it is

[cherrington17]

i get 340-355 miles a tank with my 3.4

w/ what mods?? i know you have an exhaust, probably a cai? anything else?


i average 25mpg, and its usually split 50/50 hwy/city. i got in the mid 30s when i was going to ASS (all highway)

if your car is high miles, you can try throwing a can of seafoam through it, see if that cleans it up and improves your mpg.

[BlackJack]

so I guess 15mpg in town isn't all that good? Maybe it has something to do with my tailpipe looking like a military-grade flame thrower (without using a spark kit).

[Cliff8928]

For Iridium plugs, use the ACDelco #41-101. They're the factory original plugs for the 3400. They're made by NGK.

sorry to steal the thread.. but im not sure if they answered this for you.. but is it just sucky? or is the needle fluctuating. cuz in my case its the fuel sending unit.

[CactusWill]

It sounds like alot of people have been over paying for plugs. I paid $6 each for the oem ac delco iridiums at autozone. $50 ? $100 ? Thats crazy.

[meadus101]

I was going to buy Ion's Plugs. though it was over 30 bucks to ship em.


NGK TR55 if i remember correctly. They apparently run great in the 2.4


and I mean, All I've ever used in Lawnmowers, ATVs, Motorcycles, and everything were NGK. they work. Why change?
