Description
More Spark, More Power. When you add performance modifications to your Pony like cold air intakes, headers, performance exhaust, you need a stronger spark to maximize the horsepower benefits available from these modifications. That is where Zex "Power Tune" Spark Plugs come into play, these plugs will maximize performance in engines up to 400hp.

Nickel Coated Copper Core. ZEX™ has developed "Igniter Core Technology", which puts a copper core inside the nickel ground strap. Copper conducts electricity and heat over 4X better than nickel alone, with this unique hybrid design, you get copper’s incredible electrical and thermal properties, for optimum spark and heat transfer, yet still retain a nickel shell for long life and durability. It is truly the best of both worlds.

Application Zex has specifically designed the Power Tune Spark Plugs to be used on naturally aspirated V8 Mustangs. Zex Power Tune Spark Plugs work on the following naturally aspirated Mustangs: 1996-2004 GT, 1993-2001 SVT Cobra, and 2003-2004 Mach 1.

Mustang Fitment: 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 Details

    Waste of 60 bucks

    Replaced the stock Motorcraft plugs with these and was getting misfires. Checked each one and gaps were correct and nothing was bent cracked or broken. Bought a set of NGK G-powers to replace them and the car drives like night and day. NGK for life... Zex may know nitrous, but stick to a plug company for plugs.

    They work

    I was let down just a tad by these plugs when it comes to power compared to stock. Gas mileage has significantly improved over stock though, so im happy.

    Good, Cheap, Power

    Bought these on a whim, thinking plug performance was mostly hype. I was wrong. My mileage got better and they\'re working great with my cold air intake and and high-perf exhaust.
