Signs of a Failing Ignition Coil on a Mazda 808
On a classic car like the Mazda 808, the ignition coil is a simple canister-style part that can fail from age, heat, and vibration. When it starts to go bad, the symptoms are usually noticeable and affect the entire engine's performance. Unlike modern cars, your 808 does not have a 'Check Engine Light' or diagnostic codes to point you to the problem.
Common symptoms include:
- Hard Starting: The engine cranks but struggles to start, or won't start at all. This is often worse when the engine is warm.
- Engine Misfires: The engine may sputter, cough, or backfire, especially when you try to accelerate.
- Rough Idle: Your car may vibrate or run unevenly when stopped.
- Loss of Power: The car feels sluggish and weak, and it may stall when you come to a stop.
- Poor Fuel Economy: A weak spark causes inefficient fuel burn, making you fill up more often.
Weak Spark vs. No Spark
An ignition coil can fail completely, leaving you stranded. More often, it fails intermittently or becomes weak, causing problems that come and go with engine temperature. If you experience a sudden loss of power that feels like the car is running out of gas, a failing coil is a likely suspect.
Choosing the Right Aftermarket Ignition Coil
Original Mazda ignition coils for this vehicle are no longer in production. Fortunately, the aftermarket provides several good options that meet or exceed the original specifications. The key is to choose a brand known for quality ignition components, as a cheap, poorly made coil can fail quickly and leave you with the same problems.
Brand Quality Tiers
Based on general brand reputation for ignition parts, here is how the available brands compare:
- Top Tier (OEM Quality): Brands like NGK and Standard Ignition (SMP) are well-respected choices. NGK is a known supplier for many Japanese automakers, and their parts are trusted for reliability. Standard Ignition manufactures many of its coils in a high-quality facility in Poland and is a go-to for professional mechanics.
- Mid Tier (Reliable Aftermarket): Holstein and Walker Products offer a good balance of quality and price. They market their parts as being built to OE standards and perform extensive testing. These are solid choices for a daily driver or restoration project.
- Economy Tier: Brands like Spectra and Global Parts are typically the most affordable. However, user reviews for Spectra ignition coils are mixed, with some owners reporting premature failures even with a lifetime warranty. These parts may be suitable for a temporary fix, but investing in a higher-tier brand is recommended for long-term reliability.
Pro Tip: Consider a Tune-Up
When replacing your ignition coil, it's a great time to also inspect or replace your spark plugs, distributor cap, and rotor. These parts all work together, and replacing them at the same time ensures your ignition system is in top shape.

Frequently Asked Questions (FAQ)
Is replacing the ignition coil a difficult job on a Mazda 808?
No, it is very easy. The coil is typically mounted on the firewall or inner fender and held by a small bracket. It involves disconnecting the battery, unplugging a few wires, unbolting the old coil, and installing the new one. A beginner with basic hand tools can do this job in under 30 minutes.
Do I need a special type of ignition coil?
You need a standard 12-volt, canister-style ignition coil designed for an external resistor. The Mazda 808 uses a distributor ignition system, and the coils listed for your vehicle are designed to work with this setup. You do not need a modern 'coil-on-plug' type.
Since OEM is unavailable, is aftermarket quality good enough?
Yes. For a simple component like a canister coil, reputable aftermarket brands like NGK and Standard Ignition often meet or exceed original quality. Given the age of the vehicle, a new, quality aftermarket part is a much better choice than a used, original part of unknown condition.
Are there any recalls or known issues for the Mazda 808 ignition coil?
No, there are no recalls or technical service bulletins (TSBs) from the NHTSA or Mazda for the ignition coil on the 1972-1977 Mazda 808. Any failures today are due to the part's age and normal wear and tear.
