spark plugs

hellow ppl my ignorance is back again lol so I got some money and I want to change the spark plugs on my ride, I know thwre are several options for sparks and well I found mostly platinum and copper ones, which ones are better? its a 1979 duh lol help plz!! thank b4 hand

I use the autolite plat's.

alright thx!
i've heard those sparks are pretty good but i haven't tried them myself.

Does anyone has any other suggestions?

I have heard a lot of people rave over the new E3 diamond fire spark plugs. The are about five bucks a plug, so kind of pricey, but on horsepower tv the guys did some tests on them and they increased horse power and fuel economy over the next leading spark plug (they didn't say what kind it was, but it looked like a Bosch platinum with four ground points).
Personaly those are too expensive for me. Recently I installed some NGK V-power plugs. They were only two bucks a piece and I noticed a big improvement in acceleration and response. They aren't platinum coated so I suppose they will only last as long as any standard plug, but the V groove is supposed to improve spark and rate of fuel burn.

my next step is the E3 diamond fire spark plugs, Ive used the bosch plat+4's and loved them on a v6....but never on the carbed v8.
If you are wanting the best, then go with the e3's...if you just want good plugs then get the autolites or AC delcos..but get the platnium ones either way.

i have the NGK v powers and they work good never have any trouble starting my car our with power with these plugs. even in the freaking cold. there cheep and work good.

Alright sounds good, i'm not sure which ones i'm going to take but thx for your help.
 
I have another question. Does anyone knows what are the torq specs for the plugs on a 350?

about a 1/4 or 1/2 a turn after it stops.

Oh and dont forget the anti seize make it a hell of alot easier to get them out later.

Im using Iridium plugs, but they are expensive, suposed to burn fairly hot with MSD ignition, theoretically burns up more of the fuel in the cylinder creating more HP........

just make sure they don't burn too hot.

i use autolites(ar133).its a racing plug.i got them at advance and they come with a lifetime warranty against fouling out

hey thx alot for ur help, i got a much better idea. Thx

i have a 81 z28 with a 383 stroker n i use the acdelco regular plugs and it sparks just fine. i know i had a mazda rx7 that i used the bosh platinum+4 plugs with 4 prongs and it does increase the HP, but that was a 1.1L rotary motor pushin around 195HP with a 5 speed, i would smoke 5.0 mustangs all the time!
 
bosch makes a good plug

bosch plugs definatly are a good plug. but what i dont understand is why people hate champion plugs. i work at an auto parts store and when i tell people i have a certain plug in champion its always the same "AWW MAN I DONT WANT THOSE" i dont get it. i use champion plat. in my car and the thing is awesome. please give me some insight on the champion hatred....i mean they have been around for over 100 years....

cuz they remind us of lawn motor plugs.

HAHAHA lawn mower plugs! yeah i think your right! seems that every year you have to change them damn things, i bet the auto plugs are diff in a way but i think that is a good point. i have had champion plugs and they seem to get dirty or fouled up quicker than many other plugs. exspecialy in lawn mowers. now in all my lawnmowers and small engines i run a ngk plugs.

I ran one of my car plugs in the mower...and damn, it didn't bog in the tall grass.

I installed the ngk v racing plug we changed nothing else on the car other than header gaskets the weather conditions were similar, The car was running high 8.5s in the 1/8th with the old plug and it ran mid 8.4s and a 8.34 with the ngks. I know its not a true apple to apple comparison but ther certionally seemed better to me. The old plugs were autolites non platinum.

im presuming you have 14mm taper seat short 5/8" reach plugs .
 
NGK BP7FS  or BPR7FS  if you want resistor plugs , or you can run BP6FS  BPR6FS .
 
CHAMPION  RV9YC or RV12YC  are resistors plugs , or BL9Y  non resistor .
 
HR8BC are the bosch plugs in resistor and i think its H8BC  for non resistor ..
 
AC  are  ACR45T   ACR44T .
 
theres obviously lots more that i dont know about and i guess these plugs are more older styles
