Most will tell you that for a stock engine all you really need is the stock AC Delco plugs and wires.

I have the Taylor wires and Autolite plugs.

 

Scott Performance makes a helluva wire, I also liked the Magnecors too. Really though, it's just important to get a new set on there.

 

I have Taylor 10.4 and ac plugs.

 

Taylor 10.4mm w/ NGK TR6 fed by LTCC !~FTMFW~!

 

I have Moroso 8mm wires with NGK plugs (use to have TR6 with nitrous, now BKREFS with boost) and the LTCC. No need for fancy big-bucks wire sets IMO...



are those low impedance wires with the LTCC?

 

I have MSD wires and the Delco plugs, but I need an opti.... so it is hard to tell how its running

 

Magnecors are the most durable. They don't have the lowest resistance to start with, but they don't break down, either.

 

taylor wires stock ac delco plugs great combination

 

Its started to be reported that AC delco wires have really gone down hill in qaulity, and don't be fooler by the larger numnber on the wires..8mm-10.5 mm that just means you are paying for more insulation, Its a waste on these cars, just get some taylors , or even jegs makes some f body lt1 wires that are a good price and well made.

 

I've been running Bosch Platinum +4's in all my vehicles.
I'm still have the original plug wires / Opti / and water pump in the Impala (44K miles). I have replacement parts for everything, but as long as I get good gas mileage why do it. I know changing the Opti and plug wires can be a real PITA.

You could run into header interference problems with the big boots on the Taylor wires, so be sure you have the room for them.

For the record, with aluminum heads and CIA Budgets, you don't.

Believe it or not, I've had the best luck with Belden Gold and Autozone top-liners (Duralast Gold, maybe?).

I like the NGK TR55's in my Impala, but you gotta change them once a year. I run the regular old Bosch Platinums in the wagon. I've run those for YEARS (like 15) and never had a problem. I like that they don't have platinum pucks to worry about falling off, like some other recommended plugs. I may switch to those in the SS this year, too, because I don't plan on ever running nitrous in the car anyways.

I'm about to install tri-y's and change my plugs on my 27k ss.I was about to buy some tr55's until i read this. Why do you have to replace them once a year?

 

Best plugs? I have Autolite double plats in my car with 50K miles and it still runs good. When I replace them,I'll replace with some iridiums, they are without a doubt, the best.
My '06 GTO came from the factory with iridium plugs. When I had it dyno tuned, I asked if they replaced the stock iridium plugs with new copper plugs. They didn't. So, they replaced them with brand new champion copper plugs and we did some more dyno pulls.
Same temp/humidity conditions, so how did they do against these old iridium plugs with 18k miles? Not good!
On each pull, the car put out about 1.5hp less than with the old iridium plugs. You can quibble about the negligible amount of power, but fact is that a new plug should clearly outperform an old plug.These plugs also last well too. I went through a set of the overlly hyped ngk copper plugs and after 17k miles, I can say that I noticed no difference in performance over the plats, except at 17k miles when the idle was a bit off and the plugs were worn. I hate changing these plugs and for a stock motor, I recommend iridiums with a healthy dollop of antisieze goop on the threads and you won't have to look at them again for a long time.

 

i have red MSD 8.5mm wires and AC delco plugs. been runnin smooth ever since.

 

Has anybody tried these wires?

 

I run Taylor Thundervolt 8.2mm wires with the '96 Delco double platinum plugs.

 

Just wanted to add that since I'm on my 2nd '96 SS and have to REINSTALL my CIA Gen II Tri-Y Headers that means I also may as well do plugs again since when I originally had my few mods (Headers&hi flow cats, intake, 1.6RRs, beehive valvesprings, F-body MAF, LT4 KM) that upon getting a tune I questioned Bryan about plugs and recommended to me The Autolite 104's and I got em in double plat and the car ran great the whole time...
So awhile back I recontacted him about a friends new-to-him '93 Z28 LT1 on a tune and recommended plugs and he mentioned really liking new Autolites they have that are Iridium so I believe that equivalent part# would be XP104 so I will probably try them out when I get to reinstalling my headers

 

What are the best Spark plug wires/plugs for Performance and daily driving?


Wires
taylor,msd,ac delco?

Plugs
ngk,ac delco, autolite 104's?

any other parts that I need to replace when reached high mileage?

thanks

I have been sticking with the Taylors from Summit

I went with the Taylors from Napa and AC Delco platinum plugs.

i have an 2006 impala ss with 5.3 what is the best spark plugs

This forum is specifically for 94-96 B-Bodies, check out impalaforums.com. My brother has a 06 Imp with the 3.9 and he uses Delco plugs

 

I was told to avoid autolite plugs if running headers on an LT1 because they are about a 1/4" longer than the other brands and can burn the plug wires easily, also changing them is trickier.

FALSE info.

Autolite 104s are standard length!

I would strongly recommend taylor wire, they are built to last. Taylor wires have a very good reputation in automobile replacement parts industry. They are very durable and can withstand a very high temperature.

 

I've been sticking with stock type plug wires for like $20 buck a box on wholesale
closeout from Rock Auto and the ImpalaMASTER runs 10s on spray.

I know Mr. Harris also uses stock wires and he's got a 10 second street Impala SS!

Taylor Spiro-Pro 8mm with NGK TR6, stock coil is what I've got.

 

Does anybody have any experience with the Champion Iridium spark plugs? I am trying to decide between them or the Autolite flavor....

 

"Iridium" is a marketing trick. Buyer beware
