Callaway C6 Corvette UHC-8 Ultra High Current Ignition Wire SetsWHATS THE WHOLE POINT OF CHANGING THEM I DONT GET IT NEED ADVICE

 

While I have great respect for Callaway's Engineers IMHO changing spark plug wires on a new Corvette will not provide any performance gain. Save your money. I believe it is offered as part of a package. While the packages they offer will produce real horsepower, changing the wires alone will do nothing but empty your wallet.

 

As stated, save your money on this one.
The stock wires are adaquate for the stock set up.

 

Increased spark energy isn't going to make you any more HP. Wires don't give you more spark energy. Now think about this: does it make any difference if you start a forest fire with a match or a blow torch?
You simply want a wire that is of good quality, doesn't leak energy, and has low ohms of resistance. The stock wire fits the bill. MSD 8.5mm are a good replacement when it's time.

 

It's a fact: high performance ignition wire, even Callaway wire, doesn't create more spark energy. However, OEM wires aren't used in high performance and professional racing applications for good reason.

Improved conductor, insulator, and terminal materials minimizes the spark energy loss that can occur as the current flows from the coils to the plugs. The more the engine is modified, the more ignition energy is required to initiate combustion and the more critical are the demands on the ignition system. In a completely stock engine, the OEM wires suffice. At that level, it's a matter of appearance and personal preference.

As cylinder pressures increase, as operating RPM increases, as underhood temperatures increase, the probability of energy loss at the wires increases. Because the voltage required to create an arc at the plug gap increases, the potential for leakage through the insulation increases. That's why high dielectric strength silicone jacket and boots are used in performance wire sets. The Callaway sets come with an extra layer of silicone impregnated fiberglass sleeving over the extra thick, silicone-jacketed 8mm wire, with shrink tubing sealing the sleeve to the boots. To reduce the "resistance" to current flow, new low-resistance conductors have been developed. Previously, low resistance meant EMI radiation, or radio static, which could affect other on-board electronics. Stainless steel locking terminals provide positive, corrosion resistant connection to plugs and coils.

In response to the question regarding whether the Callaway wires are only sold with Callaway packages, the UHC-8 wire sets are included in the SuperNatural and SuperCharged Corvettes, as well as offered separately.
