LEXUS SC430 4.3i Spark Plug 2007- (Eng. Code 3UZ-FE) - IFR6T-11

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

Copper / Nickel
  • Great conductivity; shorter service life
  • Often specified on older engines or performance setups
Platinum
  • Longer service intervals and stable heat range
  • Good OE-style replacement for daily driving
Iridium
  • Best durability, precise spark focus
  • Ideal for modern high-compression/turbo engines

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.

FAQs

Should I replace all spark plugs at once?
Yes. Replace as a full set to maintain balanced ignition timing and coil load across cylinders.

Can incorrect spark gaps cause misfires?
Absolutely. Too wide = weak spark and misfires; too tight = poor combustion. Always verify the gap against the manufacturer specification.

Do I need iridium plugs for a daily driver?
Follow the OEM spec. Iridium offers longer life and stable spark, especially on modern engines, but use the type and heat range your engine calls for.

Why replace coils and leads with the plugs?
Tired coils/leads overload fresh plugs and bring misfires back quickly. Replacing together restores the whole ignition system for longer.
