Spark plug wires, which ones?

[Tonny]

As Steven said, the stock wires will serve you quite well. You aren't sacrificing anything nor will you be gaining anything with fancier wires, other than aesthetics. If appearance of the ignition wires is worth the extra expense to you, then have at it.

If I recall correctly, @Rocket Man HAD to get aftermarket wires due to his headers, and MSD was the only ones that fit well enough to not burn on the header tubes. Completely irrelevant in your case.

Who says I'm not getting headers in the future? And since my original spark plugs survived 300.000 kms I just past, the difference for me will only be 20 bucks compared to MSD, because I can get them in the Netherlands, same shop where my exhaust will come from. The MSD Super Conductors are 2 inch longer, which can make the difference in space yes. For now OEM would be enough, but I might go for MSD for the color and warranty because I can buy this in the Netherlands. If I get a broken wire out of the US, after paying more for sending and taxes then the product itself, it would really suck. And here I can hop in the car for 30 miles and be at that shop if something is wrong and two year warranty. They also have Taylor wires. And Accel. And no ACDelco, so will ask the reason why to him also.

 

[Tonny]

Ok I decided. I'm going for the MSD's. Just called the shop and the guy said he always sells these wires for the 5.3s, since they are better and never had bad experience with them. Everybody has his own opinion. But warranty is a big thing for me also, and that is nearby. And I decided as my build goes on, I want the decals to be red/grey/black in the engine my Tahoe is my work truck but also my hobby. And as we have as excuse in the Netherlands: A hobby may cost some money''

My 0.2 cents, Go OEM Packard(Delphi, AC Delco).

In case of tuning I would suggest Taylor wires, or MSD.

I'm running Taylor 10.4mm wires with OEM AC Delco coils and OEM IR spark plugs

I have to 2nd the other opinions of sticking with OEM ACDelco plugs and wires. Get a good set of heat protectors/plug wire covers. DEI makes some really good products, and if you’re running anything other than standard manifold I highly suggest them in addition to their header/exhaust wrap. Take your time with the latter product and give yourself extra length when doing the wrapping. Much easier when it’s done off the vehicle as opposed to headers that are already mounted.

Tanks for the input guys. Since I can't get those originals in Europe, it doesn't cost much more to buy the MSD 8.5mm Super Conductors in a local American shop who has them in stock and no complaints about them. They are a bit longer because they fit 4.8, 5.3 or the 6.0. But MSD does not have them in 10 inch. But 2 inch longer won't be a trouble. Secondly they don't need heat shields. And since mine are still factory, wires and heat shields, I probably have to change a few heat shields too. And have the warranty. Since I got new spark plugs, the motor runs great again. Unfortunately I don't have much pictures of the maintenance last year, but this is how my bougies looked like:

Not sure if they where factory... I now run NGK's as far as I know, I think copper because I don't believe in lifetime sparks so will change them more often then the manuals says anyway. And tuning is indeed part of the build.

Not that bad as mine

ACDelco are reboxed NGK.

He mate, I don't completely understand your advice. Stick with OEM or not? And I thought of heatshields for the MSD wires for these: https://www.ajspeedshop.nl/a-46893345/bougiekabels/8x-titanium-bougiedop-heat-protector/ but the dude said it is not necessary. But aside from that, could you explain it in a other words/way so I understand your reply ?

Oef, factory at how many kms?

NGK Platinum, after 80 000km, should last about 60 000, so I am happy, no misfire...
Plug on photo are from Cyl. 8.

My apologies. My brain works faster than my mouth or my fingers, so I often confuse a lot of people. Add in the fact that I’m partially deaf, so I talk really quiet and nobody can hear what I’m saying 90% of the time. But for me it always feels like I’m yelling when I talk.

Anyways.

My previous post was suggesting that you use OEM ACDelco plugs (41-162 / 19417055) and wires. I see you’re already going with different wires, but if you have headers (or anything other than stock exhaust manifold) then you WANT heat protectors for your plug wires.

These heat shield are maybe worth if you were running Long/Short Tubes manifold, as Alpha_Omega Yukon wrote. And he also wrote to stick with OEM.

But friend have longtubes with MSD wires without heat shields, and it is OK.

I'm running stock wires with my long tubes.

Sad to hear that mate, you got that since you're born or did you got it with a accident or something?

Thanks for the explanation. I took a look @ the DEI website, looks kinda like the boots that my local American shop is selling also. So would headers ever come, I will go with a set I showed or like this which looks the same as the DEI protectors: https://www.ajspeedshop.nl/a-46848095/bougiekabels/8x-bougiedop-heat-protector-blauw/ or just the titanium ones from his website.

Yes I took a look under the hood and don't see a problem without protectors on stock headers. My headers also have headshields.

I'm running stock wires with my long tubes.

Thanks for the input. Well if ACDelco was available for a comparable price as in the US I would bought those. But because they are not in the EU, with shipping and taxes I can get the MSD's for a few bugs more including warranty. And as said, he has some ACDelco parts, he said if my others wires where so bad, I would sell ACDelco wires also..

Really appreciate all your peoples input!!

Also check Taylor, they used be made in UK, so can be also cheaper without duties.

Yes but still the problem with warranty and the pound sucks so it cost me the same as the MSD's because I can get them local.

Today my mechanic mate called that he's going to order from Rockauto. He will do a big order and will see what the ACDelco's will cost me. If they are cheaper this way I might go for the Delcos after all

Beware some delco stuff are repacked cheap stuff (advantage) Try to stick GM Genuine with delco.

I ordered Delphi, and they were OEM Packard wires.

AC Delco has 3 levels of quality. AC Delco OEM is top of the pack, followed by AC Delco Professional or Gold, which is 2nd in line and can be bad, and AC Delco Advantage or Silver which is usually crap. Just because it says AC Delco, even from RockAuto, make sure you are getting the right level of quality.
