Mace Copper Core spark plugs are engineered to deliver superior conductivity and heat dissipation, ensuring optimal performance and combustion efficiency in your vehicle. The copper core construction enhances spark plug durability and reliability, promoting consistent ignition for improved fuel efficiency and engine power.

These Copper core spark plugs suit Toyota vehicles fitted with 2VZ-FE, 3VZ-FE, 1MZ-FE and 3MZ-FE V6 engines.

Key Features:

• Copper-glass seal bonds insulator, terminal post center electrode together; assures full required voltage at spark gap; gas-tight seal (100% leak proof).
• Multi-rib insulator reduces danger of "flash-over".
• One-piece terminal post adds strength.
• Resistor reduces radio frequency interference (RFI) and electrode erosion.
• Cold-formed steel shell precision rolled threads.
• Full copper core electrode provides better performance in all conditions.

Vehicle Fitment Guide

Notes:

• You can contact us if you are unsure about fitment.
• Gap the new spark plugs as recommended in the above fitment guide or car owner's manual. Use a feeler gauge to measure the gap between the center and ground electrode. The gauge should pass through snugly but easily. If too loose or too tight, reset the gap.
