FAQs

What are the main symptoms of faulty ignition leads?

Common symptoms include engine misfires, rough idling, reduced engine power, poor fuel economy, and potential MOT emissions test failures.

How often should ignition leads be replaced?

It is generally recommended to check their condition regularly and consider replacement every 40,000-60,000 miles as part of routine vehicle maintenance.

What does 'Resistive Cable' mean for ignition leads?

Resistive cables help to suppress radio frequency interference (RFI) generated by the ignition system, which can interfere with electronic components in the vehicle.

Can I use these leads on any car?

No, these leads have specific fitment types (SAE, DIN, M4) for spark cables, distributor caps, and coils. You must verify your vehicle's compatibility before purchase.

What is the cable diameter of these leads?

The cable diameter for these ignition leads is 7mm.

How do I know which lead goes to which spark plug?

It is crucial to match the length of the new lead to the original lead it replaces and to ensure it connects to the correct terminal on the distributor cap or ignition coil.

Where are these ignition leads manufactured?

Remax, the brand, prides itself on sourcing EU manufactured products for its auto electrical parts.

Troubleshooting

Engine misfiring or running rough after installation

Double-check that each lead is firmly connected to the correct spark plug and distributor/coil terminal. Ensure leads are not crossed and are routed correctly away from heat sources.

No spark at spark plugs

Verify that the coil lead is correctly connected to the ignition coil and that the main ignition system is functioning. Re-check all connections for a secure fit.

Reduced engine power or poor acceleration

Ensure all leads are properly seated and that the cable diameter (7mm) and types are as per vehicle specification. Inspect leads for any visible damage.

Pros and Cons

Setup, Compatibility & Care Instructions

Setup:

  1. Safety First: Ensure the engine is cool and the ignition is off before beginning.
  2. Identification: Carefully note the routing and connection of each old ignition lead before removal.
  3. Removal: Gently twist and pull each lead from the spark plug and the distributor/coil.
  4. Installation: Connect the new leads to the corresponding spark plugs and distributor cap/coil terminals. Ensure a secure click or connection. Use the provided cable lengths to match the original routing.
  5. Routing: Secure leads away from hot engine components and moving parts to prevent damage.

Compatibility:

  • Spark Cable Fitment: Coupling Type SAE
  • Distributor Cap Fitment: Coupling Type DIN
  • Coil Fitment: Coupling Type DIN, M4

Always verify that your vehicle’s spark plug, distributor cap, and coil connectors match these specifications before purchase. Consult your vehicle's manual or a professional if unsure.

Care:

  • Inspect ignition leads periodically (every service or 10,000-20,000 miles) for signs of wear, cracking, or fraying.
  • Keep leads clean; dirt and moisture can impede performance. Use a dry or slightly damp cloth for cleaning, avoiding harsh solvents.
  • Consider replacement every 40,000-60,000 miles as part of routine maintenance.
