Question bout plugs and wires???

**Odawg1** · 08-04-2010, 08:23 AM

I've got a 99 SS and I've got pacesetter headers and true duals with the flowmaster 10 mufflers being installed. While the install is happening I figured I'd change my plugs and wires. Any suggestions on which ones to use. I plan on adding the ls6 intake before I do much racing. Just not sure about plugs and wires. New msd 8.5's? Need help!

NGK TR55's and MSD wires. I added DEI heat sleeves to the wires as well.

U talking the iridium plugs that are 33 dollars a 4 pack? What about the accel 9000 wires?

Do the heat sleeves make a big difference?

NGK is a brand name. You can use Iridiums also, just more expensive but supposed to last longer. I have not used Accel wires. The MSD's fit good and are not all that expensive.

One installation note: When you install the new plug wires, you should hear and/or feel one (1) "click" on the plug and two (2) "clicks" on the coil.

Thanks for the info. I was just reading on the accel wires and they seemed like the real deal by the info they give you. I just wanted to make sure before I paid 105 for them. I've heard alot of people say msd though.

I would look into taylor wires. Lot of people very happy with them. the majority seem to run msd 8.5's though. but I also hear a lot of bad rep for msd products.

I personally also went with acdelco iridium plugs. found a set for $36 and they are good up to 100K if you want to keep em that long. And no one seems to have any complaints on runnin the delcos.

Otherwise Look into Autolites...I think the ones u want are the 103's

U must use heat sheilds over the plugs...thats a must...else any spark plug boot will degrade from the heat over time...

I have always run the pricey plugs,,,since I dont wanna ever have to change them so going 75K on a set of plugs to me is wirth the price,,,plat 4 irs work great.

I would have bought the taylor thundervolts...but since I did not have them handy to buy I bought the msd wires...I noticed no diff from stock to msd wires in my stock car, but then again if they outl;ast the stocks then they would be worth it.

Else taylor thundervolts IMHO are the best

OH yah,,load up that boot internally with dielectric grease..both ends of wires,,,,this will help them come off easy and also help keep them from drying out.the rubber that is

Dielectric grease also works great if you have no KY and a dry date,,if you know what I mean,,
