The Northstar throttle body kit from ZZPerformance allows you to bolt a 2000+ Northstar throttle body onto your supercharged Series II 3800. On any positive displacement supercharger, like the M90 used on the 3800, removing intake restrictions and increasing flow goes a long way when it comes to making more power. The Northstar measures 75mm at the blower opening, making it the largest and best flowing direct bolt on option for Gen 3 and Gen 5 M90 superchargers.
This modification is recommended for those with ported inlet Gen 3 blowers, stock Gen 5 blowers or ported Gen 5 blowers. No other company offers such a good looking, perfect fitting, or as complete of a solution for your 3800.
*PCM programming or AFC needed for the different MAF.
Base kit includes:
- CNC machined adapter plate w/screw
- MAF adapter harness (with IAT)
- TPS Adapter harness
- Custom throttle cable bracket that maintains cruise control
- Silicone Coupler
- 2 Clamps for Coupler
*Will not work in drive-by-wire applications, for example the '04+ Grand Prix supercharged.
