Electical upgrades/plugs

[ScaryFatKidGT]

First I'm getting new spark plugs I want the highest performance plugs that arnt going to be a waist. Iv heard people say anything besides stock copper is a waist but other people swear by other premium plugs.

Getting a msd coil pack I remember there's 2 models that are very similar which one do I need?

What's the best plug wires I can get?

For the spark plugs i have seen in a few studies that e3 creates a better spark than just plain copper, but whether its true or not i dont know. Also premium plugs, such as iridium, is just to make them last longer not to make performance.

The msd is between an 8229 and an 8239, with the 29 being round pin and 39 being flat pin. personally i doubt that the pin type will make much of a difference at all.

Finally for plug wires i believe that magnecore is the best but ngk is better than the stock wires.

Should I go with plugs that are like 1 step colder?

I got NGK "V-Power" plugs and NGK wires.

Are you running 100+ HP over stock?

now why would you want a sparkplug that doesn't ignite your fuel/air mixture as well? Think about it for a bit.

Turbo cars run "colder" plugs to stave off detonation when the boost levels are increased. They're there as a safety measure, not as a performance one.

The copper plugs you have in there right now are you best option.

Also its waste, not the thing right above your hips :razz:

Running colder plugs is not and should not be considered an upgrade. It should only be done to correct a problem, and that is spark plugs that are overheating. Assuming the car is mechanically sound and the tune is good, the only reason you would need to run colder plugs is if they are getting so hot that they are glowing and causing pre-ignition, or getting damaged from overheating. Running colder plugs on a car that doesn't need them, especially on an older engine, will cause deposits to build on the plug and cause them to foul out.

Ok no colder plugs ha

What do you guys think about wires? Magnecor?

I've never been sold on "performance" wires. Any wires that are built to OE specs will already be low resistance wires. I typically use NGK wires. Although, in the case of my 98, I bought OE wires, simply because I was already buying a ton of other stuff at the same time (resealing the engine, head gaskets, timing belt, etc) and I get a big discount from my shop.
