Product Description

Set of Eight MSD Iridium Spark Plugs for 1969-1970 Mustangs with a 429 Engine, 1970, 1971, 1972 and 1973 Mustangs with a 351C Engine and 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994 and 1995 Mustangs with a 302 Engine.

Your restored classic or modified late-model Mustang only deserves the best, so why would you settle for basic spark plugs when you can upgrade to MSD's Iridium Spark Plugs? This set of eight plugs will increase overall power in your ignition system, give you the best combustion possible and still never corrode.

Specifically for high performance Mustang engines such as the 429, 351C and 302, these zinc and nickel coated spark plugs will require no modification to your engine, just a simple direct-fit replacement. If you're looking to get the most power possible out of your pony's ignition system, than we recommend pairing these Iridium Spark Plugs with MSD's Ignition Box and TFI Ignition Coil.

3720 MSD Iridium Spark Plug Features and Benefits:
- Plugs are machined to expose more spark to the incoming gases, which promotes the most effective combustion event possible
- Engineered to improve the efficiency of the ignition system to create the most power possible
- Engineered and designed specifically for use on performance engines
- MSD's Iridium Spark Plugs last longer than an average copper plug
- Easy direct-fit installation
- Set includes eight individual spark plugs
- Zinc-Nickel coated shell resists corrosion

MSD has created the best possible spark plug for your vintage Mustang's ignition system. These performance spark plugs are engineered to improve the efficiency of the combustion process to create more power combined with increased durability. The center tip of these plugs are made from iridium to promote the best spark and increase resilience.

MSD's proprietary ceramic material enhances the dielectric strength of the plug housing, forcing the spark to jump across the plug gap to the ground electrode. This electrode is machined to expose more spark to the incoming gases to promote the most effective combustion event possible.

Order a Set of Eight 3720 MSD Iridium Spark Plugs for your 1969-1970 Mustang with a 429 Engine, 1970, 1971, 1972 or 1973 Mustang with a 351C Engine or 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994 or 1995 Mustang with a 302 Engine from CJ Pony Parts today!
