I believe aftermarket ignition boxes are a waste of money. However, aftermarket coils can produce more spark. More spark is just that. Stronger spark will not create more power. It just ignites the air/fuel. The air/fuel is where the real power is at. With that being said, some of the aftermarket coils can be some real nice pieces that just happen to make more spark. With more spark you must have a well insulated plug wire to prevent arching. Nothing wrong with a completely stock ignition system. It will produce the same power as aftermarket. Some of the aftermarket stuff my possibly out last the factory stuff due to the fact that car companies will go as cheap as they can. 86 made another fine point. Aftermarket also allows a more presentable look under the hood. The Taylor wires that Vinnie uses are great for that. They are a good quality wire that is available in many different colors.

I guess what I'm looking at is that I have to replace my wires anyway and since I can get the heavier gauged and insulated wires for about the same price, why not? I doubt if they'd be any worse then stock 7mm wires and may give some minor advantage at least in the heavier insulation. At first I though the price was a lot more but since it's not, why wouldn't I want to buy the heavier gauge wire?

This is good stuff. Insulation is the only major advantage. Tom has a good point though. No need to spend a fortune. If the price is right, go for it.

Chrome several 2.3 TC owners used aftermarket High performance coils. Only to have a high compression load miss fire.(SPARK BLOW OUT). But some say the COP aftermarket coils are better than stock FORD. Only issue is the aftermarket stuff has to be comparable in price. Now the High Performance stuff claims more energy. Is that Current or voltage??? If you have a TFI ignition system better be ware as primary and secondary voltage and current load plays havoc on the TFI system. If you want a TFI system to work better keep it in tune. Otherwise some night the flat bed and you will be good friends. Also many car companies specify special plugs. Installing the wrong plugs in some NISSAN'S will blow the coil packs. So be advised bigger is not always better. just me could be mistaken!!!

NOTE i spend many hours on the cylinder scope and scope patterns. I have found no difference in spark voltage with or without a high performance coil. With a gap of lets say .040 the coil can only produce so much voltage. It seems like the gap dictates the voltage. If the gap increases the voltage goes up. This is void of the mixture present. Because that does also make a difference. Case in point an open plug wire will blast the scope voltage pattern of the screen. When i see excessive voltage on a particular cylinder it normally means a bad wire or excessive gap or a mixture issue in that cylinder. So if you want to increase your voltage at the plug increase it's GAP!!! That is what the HEI ignition systems did. They raised the voltage and increased the gap. If you are running a high performance coil capable of more voltage increasing the gap is where it is at. If not the stock system is totally adequate. But you put xcessive loads on the primary trigger system. And that blows modules left and right. Stock modern closed ended wafer coils are at their best. Other than COP the coils are able to produce enough spark for just about any engine combination. Thanks

The stock ford of my choice has always been the GT40. I would leave it alone and drive it as is.

Tom, I think you missed what I was trying to say. The high performance coils I believe could out last the factory because they are built well. I view the extra voltage as a by-product. They do create more voltage, or they would not be causing all the damage you are talking about. I would suggest to not go overboard on picking the coil. You also said HEI increased the gap. Not so. It increased voltage in order to jump the larger gap that can only be made larger by manually increasing it. Don't know why you mention the dangers of using different plugs. I recommend to never ever run anything other than factory. Aftermarket products are wonderful because you do not have to deal with the local Ford parts department. If you go aftermarket, you better go with the high performance stuff, or you just get . I feel we are getting off track of the OP's question. To answer that question, which we have done already, the only gain to performance plug wires is insulation. He just should not break the bank for the extra insulation.

True........... But the performance stuff will run better and last longer than the cheap aftermarket stuff.

Since the subject of spark gap came up. What would be the best gap for a 1988 5.0? My old plugs seemed to be set at .54, but I looked it up online on a couple of sites and it was listed at .50. My emissions tag shows .48-.52, so I went with .50.

The problem with the TFI module (from the OE point of view) is it's mounting. On our cars and other older TFI vehicles, it's mounted to the distributor and it collects a lot of heat there. This is why in 89 and on you see the TFI remote mounted in a heatsink. I've got one of these sitting around waiting for my ambition to catch up. I'm going to remote mount my TFI in a lapped heatsink with Arctic Silver 5. I'll probably mount it to the inner fender behind the headlight where it can get some airflow across it.

My old 86 had 1985 motorcraft wires on it when I did plugs and wires at 235k.

Not any high performance motor or anything, but i'd like to see some aftermarket wires hold up to the same claim. Engine ran smoth as can be, ate 2 quarts of oil a tank, but flew through emissions and never missed till I started messing with it as a 16 year old kid.

I actually really like bosch parts, mainly because they are a builder and supplier of stock and oem parts...

OK here is the deal. When the feds made it mandatory for engines to hold a tune for 50K the car companies had to come up with a better ignition system. Capable of producing more spark. NOT VOLTAGE. (DWELL TIME OR SATURATION) Basically the old type oil filled round coils are 6 VOLTS!!!!! This went on till app 1971 or so.
:burnout:

6 VOLTS!!!!!, Tom you should be ashamed. You know better! The purpose of a coil is to multiply voltage. Otherwise, a coil would not be needed. It takes at least 15,000 volts for electricity of this amperage to jump the gap of a spark plug. Car companies shot for 20,000 volts. When HEI came out, voltage went to 40,000 +. That is automotive basics that can be learned first year at an automotive school.

I believe tom was talking about the old style coils and electrical systems that fed the coil, not the output from the spark plugs.

And electricity will jump .40 at much less the 40kv, but amerage and strain on the electrical components will greatly increase to hadle the additional load. I gap my plugs anywhere from .35-.45. Generally I open a package of 4, mesure what there gapped at, then match them all to the same gap.
