I just burned out my seond set of spark plug wires courtesy of my MSD 6A box. The first was a stock replacement type made by Bosch that lasted about 3 months before the radio started acting up,the engine started missing and my SDS started throwing error codes. After some trouble shooting to find the problem I searched my "inventory" and found a set of 8mm Taylor Spiro-Pro wires that I bought about 10 years ago. Put them on and all problems were immediatley solved,for about a week. The Taylor wires are really good quality and I used this set successfully with a MSD long ago so I'd have to guess the failure was due to age. Moral of the story is if your going to use a high output ignition save yourself the trouble and don't put a $20 set of plug wires on your engine. Better yet if you aren't running a turbo or ultra high compression don't bother with any ignition add ons since they are just a waste of time & money.

Yea, I'm in the process of upgradeing my ignition, and i'm going to use the MSD supercoil plug wires, the 8.5 mil and run for about $80.00, $71.93 through summit it is a universal plug wire kit for 6 cylinders. Were you cut the cable to length then put the boot on.

I ordered a set of MSD Heli-Core wires from Jegs for $49.95. I've got the MSD box,BTM boost retard unit and Blaster coil so I may as well keep it all in the family and try their wires. We'll see.

1. Vic Brit has 8.5 set from Crane for $40.
2. I am preparing to add a 6A or 6AL. My mechanic says it will solve many problems, like no power 1000 - 2200 R and fade over 4500 R. He says it will also run 'cleaner' in all ranges and gears. Now someone says not to do it????? Is it all hype?

It is a worthwhile mod - I wasn't expecting much on a stock motor but it definitely revs and idles more smoothly. It is a nice clean instal too and made hooking up my aftermarket tach a breeze.

Like I said,if you're not running a turbo at 15+psi.,turning 7000+rpm or over 10.5-1 CR don't bother. A stock electronic ignition in good shape and properly tuned will work as well as any aftermarket set up. If you have points try a Pertronix kit for $70. I could think of better ways to spend a couple hundred bucks on myself or my car instead of buying a amplifier box and plug wires but it's your money do what you want.

It is a worthwhile mod. Your mileage will increase, as you burn your fuel more efficiently (multiple sparks at lower rpm). Your top end performance will increase with the hotter spark above 5K.

Don't let anyone tell you a good ignition is a waste of money. Sounds like toms78zxt just doesn't believe in "wasting money" on an inferior NA motor.

While the stock ignition is good, it is also 20+ years old. Believe it or not, there have been improvements made since then! Take advantage of them. Get the best you can afford.
