Choosing the Right Ignition Coil for Your 1972-1979 Renault R17
Keep your classic Renault's spark alive with a reliable new ignition coil.
- A failing ignition coil on an R17 causes obvious issues like misfiring, stalling, or a no-start condition.
- Replacement is a very simple DIY job that takes less than 30 minutes.
- Invest in a reputable aftermarket brand like NGK or Standard Ignition; economy brands have reports of poor reliability.
- A modern aftermarket coil is a reliable upgrade over aged original or New Old Stock (NOS) parts.
Signs of a Failing Ignition Coil in Your R17
On a classic car like the Renault R17, ignition coil problems are common due to the age of original electrical components. The symptoms are usually straightforward since there are no complex computer systems. Watch out for these signs:
- Engine Misfires: The car may sputter or hesitate during acceleration because a weak spark isn't igniting the fuel correctly.
- Hard Starting or No-Start: A dead or very weak coil won't produce enough voltage to create a spark, preventing the engine from starting.
- Poor Engine Performance: You might notice a general lack of power, sluggishness, and worse fuel economy.
- Stalling: The engine may stall unexpectedly, especially when it's warm, if the coil is failing under heat.
- Backfiring: Unburnt fuel may explode in the exhaust pipe, causing a loud pop. This can happen when the coil fails to fire a spark at the right time.
A Note on Original Parts
Finding a brand-new, original equipment (OEM) Renault ignition coil from the 1970s is nearly impossible. Any available are "New Old Stock" (NOS), meaning they are decades-old parts that have never been used. While authentic, a 50-year-old electrical part can be less reliable than a modern, high-quality aftermarket replacement.
Choosing the Right Aftermarket Ignition Coil
Not all aftermarket brands are created equal. For a classic European car, choosing a brand with a reputation for quality ignition components is important. Here’s a breakdown of available brands, sorted by general market reputation.
Tier 1: Premium Reputation
These brands are well-regarded for quality engineering and often improve on original designs.
- NGK: A global leader in ignition parts, NGK is known for its OE heritage and rigorous testing. They have a strong reputation for reliability and performance, making them a top choice for any vehicle.
- Standard Ignition (SMP): A long-standing American company, Standard Motor Products has a good reputation for making durable parts that often fix the weak points of the original designs. Be sure to choose their main line, not the budget "T-Series."
Tier 2: Standard Replacement
These brands generally offer OE-equivalent quality and are a solid choice for most owners.
- Walker Products: Walker markets its products as meeting or exceeding OE standards, with a focus on reliability. They are a decent mid-range option.
- Holstein: Holstein claims to use high-quality materials and extensive testing to meet or exceed OE specifications. They offer a good warranty, suggesting confidence in their product.
Tier 3: Economy Brands
These brands compete on price, but owner reviews suggest caution. While the low cost is attractive, they may not offer the same long-term reliability.
- Spectra: Despite offering a lifetime warranty, some users report experiencing repeated failures with Spectra coils, leading to multiple replacements.
- Skyward (SKP): Generally considered a budget-friendly brand. Some forum users advise against using their electrical components, suggesting reliability can be a concern.
Pro Tip: On an older vehicle, the ignition coil is a simple but critical part. Spending a few extra dollars on a reputable brand like NGK or Standard Ignition can prevent you from being stranded and ensure your R17 runs smoothly for years to come.

Frequently Asked Questions
Is replacing the ignition coil a difficult job?
No, it is one of the easiest jobs you can do on your R17. The coil is usually mounted in an accessible location in the engine bay. It involves disconnecting the battery, removing two or three wires, and unbolting one or two nuts that hold the coil bracket. This is a great DIY task for any skill level.
Do I need a special "classic car" ignition coil?
You need a canister-style coil designed for a distributor-based ignition system without an external ballast resistor, unless your specific car has one. Most universal canister coils of this type from a quality brand will work perfectly. The key is to match the primary resistance, but standard coils from reputable brands are generally designed for this type of application.
Are there any recalls or technical bulletins for the R17 ignition coil?
No, searches of the NHTSA database and other technical resources show no recalls or Technical Service Bulletins (TSBs) related to the ignition coil for the 1972-1979 Renault R17 in the North American market.
Should I replace my spark plugs and wires at the same time?
It's a good idea. If your ignition coil has failed due to age, your spark plugs and plug wires are likely just as old. A new, powerful coil can stress old wires and plugs, causing other issues to appear. Replacing all ignition components at once ensures a strong, reliable spark for optimal engine performance.
