HV3 High Velocity Intake Insert

ZZ-HV3-SII $139.99
Engine
Regular price $139.99

Includes:

  • HV3 insert
  • Upper intake gasket
The High Velocity Upper Intake Manifold Insert replaces the factory plastic runners in the upper intake manifold found in FWD Series II and III 3800's. All you do is simply remove the upper intake (leaving the throttle body attached), pull out the stock runners, set the HV insert in the intake and bolt it back down! 30HP in 30 minutes!

By changing the intake tuning we are able to achieve performance numbers previously unheard of in the L36. In short we gained 9 peak WHP and 30 WHP at 6000rpm.

When coupled with ER rockers and our High Velocity Thrtottlebody the performance surpasses dyno #'s of cam'd L36's not using our insert.

More torque - The HP gains of the old HV2 were quite amazing. The only issue was a slight loss in low end torque below 2000rpm. The revised design has a slightly longer runner and a smoother transition to the head ports so the torque loss is near zero compared to the stock runners!

More reliable - The HV3 does not require RTV, cannot be seen by anyone looking at your external engine, and it comes with a new intake gasket. Installing the new HV3 actually improves the reliability of your car by replacing a potentially worn out gasket. Because it sits entirely inside the intake, there are zero sealing issues.

Does not work on factory GTPs or L67s or F-body. FWD L36/L26 only!

Good replacement

This insert was very easy to install and fits perfect. Seems to make good power too.

Intake insert

Purchased with the upper and lower intake gaskets and upper intake. Haven't pushed the engine after installation to see if the is a difference in horsepower, but it seems to run better with the insert.

HV3 High Velocity Insert

Haven't had a chance to install this yet, waiting for the weather to break. Very well constructed, durable insert, to match with the new Upper Intake. Looking forward to spring. Shipping was really fast, as usual.
