What is the function of spark plugs

1, Improved Fuel Economy

2, Faster Starts

3, Enhanced flame propagation for increased engine efficiency

All resistor plugs with single ground electrodes feature a patented U-groove design, resulting in a hotter spark.

All *platinum-tipped plugs* are designed to last up to 60,000 miles before replacement.

For newer Toyota vehicles with distributor less ignition systems , replace your original spark plugs with the same dual ground electrode platinum-tipped plugs that came standard with the vehicle — single ground electrode plugs offered by competitors will only last one-half as long.

Tip: Be sure to check to see if there are platinum or iridium spark plugs available for your vehicle.

Iridium spark plugs can last up to 120,000 miles!

To ensure the most trouble-free operation of your Toyota, please check your vehicle’s Scheduled Maintenance Guide or consult your Toyota dealer for proper spark plug change intervals.
