MSD Ignition – Coil; Ford 4.6/5.4L 3-Valve 04-08 Single (Part No.8243)

Coil; Ford 4.6/5.4L 3-Valve 04-08 Single

from

$70.99
The improved spark energy and voltage of MSD’s blaster 2 coils, combined with reliability, have made them a favorite for performance enthusiasts. Whether firing a restored BOSS 429 or a Saturday night circle tracker, the blaster 2 has always gotten the job done. MSD is excited to offer blaster coils for late model Ford engines with coil-on-plug technology. The new blaster COPs are designed as a direct bolt-in replacement coil for many SOHC Modular Motors. The housing and installation are the same as the factory, but that’s where the similarity ends. Inside the MSD red housing, engineers spec’d better material to assemble the primary and secondary windings. There is also patented dual magnet technology to step up the output. Together, this combines a coil that produces higher voltage and spark energy. The coil-on-plug design of the blaster COPs puts the spark energy right out of the coil and across the plug gap to improve the combustion and output of the engine. The blaster 2 COPs are available individually or as a complete set of eight.

Product Features:
  • Fits 2005-2009 4.6L And 5.4L 3V
  • Improved Spark Energy And Voltage Output
  • Patented Winding Design and Materials
  • Direct Bolt-In to Factory Connectors

MSD Ignition – Wire Set; Super Conductor; Ford 351C-460 with HEI Cap (Part No.35389)

Wire Set; Super Conductor; Ford 351C-460 with HEI Cap

from

$181.99
The MSD 8.5mm super conductor wire is the performance wire. 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 12 inch length of super conductor wire there is 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 it’s 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 is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective electro magnetic interference (EMI) or 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 produce a sleeve that is highly resistant to high heat as well as abrasion and tears. Available in universal kits and bulk lengths.

Product Features:
  • Bolt-on Performance
  • Custom Fit For Make And Model Listed
  • Wires Are Pre-Cut To Exact Specifications
