Street Tune-Up Kit | 5VZ-FE

OEM+ Street Tune-Up Kit

Restore the legendary smoothness of your Toyota V6 with the LC engineering Street Tune Up Kit. Specifically designed for the 3.4L 5VZ-FE engine found in the Tacoma, 4Runner and Tundra, this kit focuses on refreshing the two most critical components of your ignition system. By utilizing premium, stock-replacement parts from industry leaders like NGK and Denso, we provide a cost-effective way to prevent misfires, improve fuel economy and ensure your engine maintains its factory performance standards.

The 5VZ-FE utilizes a unique waste-spark ignition system that is notoriously sensitive to spark plug and wire quality. This kit eliminates  the guess work by providing the exact components required to keep your V6 running at peak efficiency for another 100,000 miles.

Kit Components & Features

• NGK or Denso Spark Plug Wire Set: Choose between the world’s two most trusted manufacturers for Toyota ignition components. Both options feature high-quality EPDM rubber insulation and superior RFI suppression. These wires are precision-length to match the factory routing over the intake plenum, ensuring a clean install and long-term durability against engine bay heat.
• NGK Dual-Ground Spark Plugs (BKR5EKB-11): The 3.4L V6 was engineered from the factory to run dual-ground electrodes. Using standard single-ground plugs can lead to premature wear and uneven combustion. These NGK V-Power dual-ground plugs are the professional choice for the 5VZ-FE, providing a consistent spark and a longer service life than generic alternatives.
