This upgrade kit includes all of the necessary parts needed to upgrade your Nissan Frontier Supercharger Kit to one of our higher performance levels.

Available Options:

• Pulley Type - Select the pulley size/level that matches the power output you are seeking. Currently, only the 85mm / Level 2 pulley is supported. Included with this option is the corresponding belt needed for the selected pulley.
• Tune Type - This option allows you to purchase a retune and only applies to customers who are already tuned by Z1 Off-Road. A retune is MANDATORY before your vehicle can be driven on the upgraded pulley and belt.
• Intake Type - Through this option, you can opt to purchase an intake tube for Level 2+. If you did not originally purchase the upgraded tube, you will need it for the higher power levels.
• Spark Plugs - Z1 recommends colder spark plugs for all power levels above Level 1. Through this option, you may purchase a set of Genuine Nissan VR30 Spark Plugs, Z1's plug of choice for supercharged Frontiers.
• Fuel Pump - All vehicles with a Level 3+ pulley will need an upgraded low-pressure fuel pump. When these power levels are made available, you will make that selection here.

Pulleys Available:

• 85mm // Level 2 - This pulley supports approximately 320whp and 295tq on 87 octane fuel, and 351whp and 307tq on 93 octane fuel.
