Hey, im going to buy a new set of spark plug wires. Was sure to buy some NGK, then heard of the MSD, but dont know anything of those wires.

Im going to mod my S5 mild to 300-330bhp incl. streetport.

well, are the NGK just fine, or should i go with the MSD if i have the "extra" money?

On ebay there is a set for 56$ for new MSD + 2,50$ shipping, but on summit racing i can get the NGK stock wires für 22$ lol, so i could buy 2 sets of NGK for the price of 1-set MSDs

do you recommend the MSD?

thanks for any replys

You NEED those

 

those what? dont see anything under that link, and i can't read japanese

want to buy from the USA only

 

ngk are oem, msd are what i ussuakly run and i like them. i ussualy go 10mm vs stock 8mm thickness. it has more heat protection and less interferance. plus they are pretty easy on the wallet and to me the thicker 10mm look nicer in the bay.

 

we have allways used the NGK even on most HP applications, they fit well and can handle some abuse.

 

Link works fine for me. They are re-amemiya wires. I have a set on my vert(were there when I got it) and they work pretty well.

 

the MSD for the FC 87-91 are 8,5mm and the stock NGK are 7mm as i read up

 

For the most part wires are wires as long as its a name brand. you might see a little difference between them but mainly its in the coating and ends, which sway your purchase. at least for me anyway.

 

that is true, my mistake. stock 7mm msd is 8.5 and 10mm

 

i was suposed to buy the NGK, but now i found out the MSD are "only" 20$ more then NGK (average price) so i thought of buying the MSD.. is it wort it to spend the more money?
it seems the MSD have better heat protection, and they look very sweet lol

 

thats about all thats between the 2. to me the msd are worth the extra 20 just for the color and thicker housing. thats the 10mm on my fb

 

All wires are not made equal. Different types of conductors, contact points and coatings affect longevity, and performance. Some have lower or higher resistance than others, and in all the wires that I have put on a multimeter the MSDs may be bigger but they usually have the higher resistance of say an NGK or an ACCEL.

 

haha ok, thanks for replys they will stick together with my red-painted plates and red-vacuum hoses

 

but thats what... 1 maybe 2 hp in the worst case. plug wires ussualy wont make or break you unless youve got some serious work done

 

hmmm.. is there any displacement of timing bc of the higher restistance of MSD?

 

if so its so miniscule itsn ot worth worrying about. if you could measure such a small amount it would probably be less than 1/10 of a degree, if that. of course thats just an educated guess, dont quote me, ive had my share of wrongs

 

1 or 2 hp can add up as well as better idle, smoother revs and better fuel economy. But low resistance isnt everything in a wire.

Lets have a quick lesson on wires.

Lets say you have the big fancy 60000volt coils)alternating current). THis does not flow through the whole wire like you can read on a mulitmeter, but instead flows around the outter most surface in a magnetic field.

Also, silicone hides the wires high resistance when the overall conductor is measured with a test ohmmeter. This only measures the lowest resistance of the wire under the conductive coating and ignores the high resistance of the outermost conductive coating in which the spark energy actually travels.

What you are really looking for in a wire is one that has a EMI suppersion type wire. This is where most of the power on a ECU controled car comes from. With out EMI suppression the wire can emmit EMI(electromagnetic interference) which can mess with diffent sensors on the motor and the computer itself.

 

Haha, cool we have the same "quote thingamajig!" You realy Russian, dude? Cool.

As for the threadstarter: DUDE.. if you dont know which plug wires to buy, maybe a 300+ HP build might not be such a good idea? lol, what do I know, im facing my first rebuild if i get this car i'm looking at...

 

I think that is the point of forums. To ask opinions and ask questions, no matter how trivial they may be. At least this is a valid question unlike alot of posts I see

 

i have a set of msd super conductor wires (8.5 mm), and see no problem in getting them in your case. didn't see and negative gains in getting them. if you have the spare $, get them. just my .02

 

magnecor 8.5s on mine. have been working great

 

Read the info on the Magnecor site and you'll find that if the plugs wires being removed were in good condition, no additional performance increase will be generated from using the Magnecor wires.

Here's some info from Magnecor:

How much extra horsepower can I expect when I fit Magnecor Race Wires ?
Despite what is published in advertisements and some vested interest magazine articles, no spark plug wires will generate or "install" additional horsepower

Do I need an 8.5mm or a 10mm size wire if my original wires are just 7mm (or smaller) ?
The major advantage Magnecor Race Wires have over conventional 5mm, 7mm and 8mm wires is that neither the high-capacity conductor nor the insulating jacket will wear out during the life of the engine.

 

The one or two HP i was talking about would be from the switch from a bad wire to a good one. If he is still running the original wires that came one the car(happens more than you think)then there will deffinatly be a difference, but all this differece will be in the idle and any power the engine may have lost due to a faulty wire.

 

just stick with NGK wires, MSD wires I have found to die prematurly on most cars I have built or work on, accel are no good either IMO I have tested accel wires and from one to the next they have all different resistances..

NGK to this day remains OEM because they have a tried and true product
