    from

    $289.99
    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:

    Hypertech – Speedometer Calibrator Color: Recalibrate your speedometer to account for changes to tire size (Part No.3300)

    Speedometer Calibrator Color: Recalibrate your speedometer to account for changes to tire size

    from

    $239.99
    If you’ve installed tires that are larger or smaller than original equipment tires, or if you have installed a ring and pinion gear set with a different rear gear ratio, the Max Energy Spectrum allows you to re-program for correct speedometer readings, as well as correct part-throttle shifting. The vehicle’s computer calculates your vehicle’s speed based on the diameter of the stock tires. If you’ve installed taller or shorter tires, or changed the rear gear ratio, the vehicle’s computer doesn’t know how fast your vehicle is going. As a result, the automatic transmission may not shift correctly and the speedometer readings will not be accurate (as required by law).

    Product Features:
    • Speedometer correction for multiple tire sizes
    • Return back to factory settings
    • Reads/Displays/Clears Diagnostic Trouble Codes (DTC’s)
    • Internet updateable
    • Product might not be available in all states due to local laws.
