Spark Plugs — Precision Ignition, Clean Power

Restore crisp starts, smooth idle, and efficient combustion with OEM-grade spark plugs. Correct heat range and gap deliver better throttle response, lower emissions, and improved fuel economy — especially under South African city traffic and highway loads.

What these spark plugs restore

• Reliable cold starts and stable idle
• Sharper throttle response with fewer misfires
• Cleaner burn for lower fuel use and emissions
• Consistent ignition under load and high temperatures

Choose the right plug type

When to replace

• Hard starts, rough idle, poor fuel economy, or misfire codes
• Mileage at or beyond OEM service interval
• Visible fouling, cracked insulator, worn electrodes

Installation & best practice

• Match by engine code and OE reference; confirm heat range
• Set/verify spark gap where applicable (many iridium plugs are pre-gapped)
• Use anti-seize only if manufacturer specifies; torque to spec
• Replace in a full set; inspect/replace ignition coils and leads if worn
• Clear fault codes and road-test for smooth acceleration

Images are illustrative. Always verify by VIN, engine code, and OE part number for perfect fitment.
