ACCEL now offers the cure for burnt spark plug boots with Extreme 9000 Ceramic wire kits. The 8mm Ferro-Spiral core wire now has ceramic boots on the spark plug end of the wires. Ceramic boots withstand up to 2,000 degrees. Great for running headers with close tolerances, an engine bay with little room, or an RV with boots that melt because of heat. Ultra high temperature double silicone construction wire rated at 600 degrees fahrenheit peak. 500 ohms/ft Ferro-Spiral core developed for performance use. Excellent energy delivery to the spark plugs, while providing the highest level of RFI/EMI suppression. Stainless steel spark plug terminals for maximum spark energy to the plugs. Pre-made to factory lengths for a perfect fit.

Most modern electronic ignition systems require suppression style wires to preserve sensitive components. Flame-Thrower 8mm Custom fit MAGx2 wires provide enhanced RFI suppression and dual current paths for more power delivered to the spark plug. Our custom wire sets have factory terminated ends for a superior connection and perfect fit, without cutting, crimping and splicing.

JBA PowerCables ignition wires are less than half the resistance of most factory wires, which frees sparkenergy and increases performance! Get as much as 5+ hp gain with JBA PowerCables as tested by CarCraft Magazine.

“Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire: incredibly low resistance without electronic interference. In a single 11-inch length of super conductor wire, there are only 40-50 ohms of resistance. That is the lowest resistance of any helically wound wire. To accomplish this, we use a copper alloy conductor due to its great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there are over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferromagnetic impregnated center core, produces an extremely effective Electro Magnetic Interference (EMI) “”choke.”” This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produces a sleeve that is highly resistant to high heat as well as abrasion and tears. The MSD’s 8.5mm spark plug terminals feature dual drimp terminals. As the name implies, the terminals feature two crimps: one for the sleeve of the wire and another separate crimp to grasp the conductor.”

TSP’s premium ignition wires are designed for superior performance and durability. A spiral-wound Kevlar? core suppresses RFI (radio-frequency interference) and features 500 ohm per foot resistance for excellent performance. Around the core is a fiberglass braid which provides superior pull strength. The outer jacket is composed of premium high-density silicone rated at 450? F and features a quality gloss finish to resist damage from water and chemicals. This set is not assembled but comes with LS-style terminals for a universal fit.

The Street Fire Spark Plug Wires feature a low resistance conductor that’s wrapped in a sleek and durable black sleeve.

When it comes to plug wires, resistance is king. The Street Fire Spark Plug Wires feature a low resistance (500 ohms per foot) conductor that’s wrapped in a sleek and durable black 8mm sleeve. A helical wound Kevlar-core combination provides an EMI-Noice resistant path from coil-to-plug. The heavy-duty terminals are wrapped in black silicone boots that protect the conductor from engine heat to ensure spark delivery. Light the fire, not your wallet-with MSD Street Fire.
