Why upgrade

The basic requirements for a properly running engine are fuel, air, compression, and spark. Before cranking up the boost in your flat four, it is wise to ensure all maintenance is up to date and these processes are performing as intended. These kits are engineered around real chassis packaging, so hoses, coolers and adapters line up without fabrication on the listed years. Follow the published torque specs and install guide, reuse sensors where instructed, and confirm clearances if you run other supporting mods. Every unit ships with the Mishimoto Lifetime Warranty for as long as you own it.
