Choosing the Right Aftermarket Ignition Coil for Your 1955-1956 Studebaker E16
Keep your classic Studebaker running strong by understanding its unique ignition coil needs.
- Verify your truck's voltage (6V or 12V) before ordering a new coil to ensure compatibility.
- A failing coil will cause noticeable issues like hard starting, misfiring, and poor performance.
- Replacement is a simple DIY task that takes less than 30 minutes.
- For reliability, consider established brands like NGK or Standard Ignition; it's good practice to also replace points and condenser.
Is Your Studebaker E16's Ignition Coil Failing?
For a vehicle from the mid-1950s, the ignition system is straightforward. However, parts do wear out. Heat and vibration are the primary causes of coil failure over many decades. An aging ignition coil can lead to a variety of noticeable problems. If you're experiencing any of these issues, your coil might be the culprit.
- Hard Starting: The engine cranks but struggles to fire up, or won't start at all. This is a classic sign of a weak spark.
- Engine Misfires: The truck may run rough, hesitate, or stumble during acceleration.
- Backfiring: Loud pops from the exhaust can occur when unburned fuel ignites in the exhaust system due to a weak or mistimed spark.
- Sudden Stalling: The engine may die unexpectedly while idling or driving.
- Poor Performance: A general lack of power and reduced fuel economy can indicate that the ignition system isn't working at its best.
Pro Tip: Check Your Voltage
Before replacing parts, confirm your truck's electrical system voltage. Studebaker began switching from 6-volt to 12-volt systems around 1955-1956. A 1955 model is likely 6-volt, while a 1956 could be 12-volt. Some trucks may have also been converted from 6V to 12V by previous owners. Using a coil designed for the wrong voltage will result in poor performance or damage. A Spectra Premium coil is noted as available for 6-volt systems.
Choosing a New Aftermarket Ignition Coil
For a classic like the Studebaker E16, finding original "OEM" parts is nearly impossible. The market consists of New Old Stock (NOS) parts, which can be unreliable due to age, and modern aftermarket replacements. Modern aftermarket coils often provide better reliability and are engineered with newer materials and technology.
Aftermarket Brand Tiers
When shopping for a new coil, you'll find several brands available. Here’s a general breakdown of what to expect:
- Premium Aftermarket (NGK, Standard Ignition 'Blue Streak'): Brands like NGK are known for extensive testing and using high-quality materials to meet or exceed original specifications. Standard Motor Products (SMP) is a long-standing company, and their 'Blue Streak' line is considered a higher-quality option. These brands are a solid choice for reliability.
- Standard Aftermarket (Spectra, Standard Ignition): Spectra Premium and the standard line from Standard Ignition (SMP) offer a good balance of quality and value. They are dependable direct replacements for daily drivers and are widely available. However, some user reviews for SMP have noted inconsistent quality in recent years.
- Economy (Skyward, other store brands): These are typically the most affordable options. While they can get your truck running, their long-term durability might not match that of the more established brands. For a classic vehicle where reliability is key, it's often worth spending a little more for a well-regarded brand.
Aftermarket Ignition Coil Cost for 1955-1956 Studebaker E16
| Brand Tier | Example Brands | Estimated Price Range |
|---|---|---|
| Premium Aftermarket | NGK, Standard Ignition (Blue Streak) | $35 - $52 |
| Standard Aftermarket | Spectra, Standard Ignition (Standard) | $28 - $40 |
| Economy Aftermarket | Skyward, various store brands | $23 - $30 |
Frequently Asked Questions (FAQ)
Do I need an external resistor with my new coil?
It depends on the coil and your system. Many ignition systems of this era used an external ballast resistor to reduce voltage to the coil during normal operation. Some modern replacement coils are designed to work without one, while others explicitly state "external resistor required". Always check the specifications on the new coil. Using a coil that requires a resistor without one can cause it to overheat and fail prematurely.
Is it difficult to replace the ignition coil on my E16?
No, this is a very straightforward job for a DIY mechanic. It typically involves disconnecting the battery, removing one or two electrical wires from the old coil, unbolting the coil from its bracket, and then installing the new one in reverse order. The entire process usually takes less than 30 minutes.
Should I replace other parts at the same time?
Yes, it's a great idea. Since the ignition coil works with other components, it's good practice to also replace the points, condenser, and distributor rotor during a tune-up. This ensures the entire ignition system is refreshed and working together reliably.
Are there any recalls for the Studebaker E16 ignition system?
No, there are no active recalls listed in the NHTSA database for the ignition system on a 1955-1956 Studebaker E16. Given the vehicle's age, any such actions would have occurred decades ago.
Technical Specifications
Cylindrical 'can' style coil. Requires compatibility with either a 6-volt or 12-volt system, depending on the specific vehicle. May require an external ballast resistor. Connects to a distributor via a high-tension lead.
