Ignite Your Mustang to More Power And Efficiency (94-98)
When Should I Replace My 1994-1998 Mustang’s Spark Plugs?
Like tires and filters, a Mustang’s spark plugs degrade over time and should be replaced. It’s recommended to replace your old spark plugs every 30,000 to 60,000 miles. You can check your owner’s manual to review the recommended mileage for replacement. Spark plugs are often a forgotten about upgrade, but they can play a very important role in helping you to gain back any lost power and at a very reasonable price. If you want to provide your Mustang with a cleaner and more efficient spark, you should definitely invest in some new plugs.
What Kinds of Spark Plugs Are There?
There are (3) three main types of spark plugs: replacement, upgraded and colder plugs. The plans you have for your Mustang will help you in deciding which type best suites your needs.
Mustang Replacement Plugs
OEM level plugs will help you regain the lost power that has slowly disappeared from your engine. They’re great for stock engines and lightly modified engines. Ford Motorcraft makes a great replacement OEM spark plug that will help to restore the lost horses.
Upgraded Spark Plugs for 1994 1998 Mustangs
Upgraded plugs will often have more advanced components and include features that help to create a more efficient spark. Some of those features include a stronger Iridium or Platinum tip, anti-corrosion properties and better conductivity then the Mustang specific, replacement level plugs. These are great for stock or modified engines and really work best for most applications. Upgraded offerings from NGK and Ford Racing help to give your Mustang that extra spark it was missing. NGK’s Iridium IX Series and G-Power Platinum are both great options for an upgraded plug.
Colder Spark Plugs - Forced Induction Mustangs
A colder plug is referring to the heat range of the plug and they help to eliminate detonation in boosted applications. These spark plugs should are meant to be used specifically for Supercharged, Turbocharged and Nitrous Applications. Stock Mustangs will not benefit from using this style plug. Zex and Ford Racing both offer plugs that are excellent for boosted applications.
Complementary Modifications When Replacing Your Mustang’s Spark Plugs
When you’re on the hunt for that like-new spark your Mustang had right after rolling off the assembly line, doing a complete maintenance overhaul will provide the greatest gain that you are sure to feel. In other words, when you grab a new set of spark plugs, grab a new set of spark plug wires to transmit the spark more efficiently to your new spark plugs.
1994-1998 Mustang Coil Packs & Distributors: With 1994-1998 Mustangs, another complementary upgrade is the coil pack. Coil Packs make more power than the wimpy stock coils to improve throttle response and produce more HP and TQ. If you have a 1994-1995 Mustang GT, you can take it one step further and upgrade to a stronger CNC machined billet distributor. The ignition system is full of components that help give you the spark you need to keep your pony’s power!
