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 Throttlebody 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.

HV3 INSERT

Installed the insert in one afternoon last week along with new upper intake. Pulls the old BONNEVILLE around pretty good. Power really comes on in the higher RPMs. Old MANS HOT ROD. LONG LIVE THE 3800.

Hv3 insert

Great product. The biggest bang for your buck. 30 hp in 30min. Looking forward to them getting more back in stock, I plan to set up another car with this insert as well. Two thumbs up!!

HV3 Insert

Installed the HV3 in my 99 Lesabre. Had to do some minor grinding on it since my intake is an aftermarket unit. The low end from start to about 3500 rpm seems very slightly weaker, above 4500 feels stronger as it builds and above 5500 there is a strong increase. My wheel spin from take off is still there but is now minimum so it saves tires which, I believe, gives a little better out of the pit time. Power comes on strong around 25 mph and builds progressively. This is on regular 87 octane getting 28 on hwy. Other mods are dual exhaust as on Bonneville ssei or 96 park ave w/supercharger, stainless zzp power log, zzp 3800 1.0 pcm, 180 degree thermostat heavier rear stabilizer, Moog suspension bushings, tie rods, ball joints and a little tighter struts, GS Regal 16" wheels and Michelins. A grandpa car no longer but more like a GS400. Thanks ZZP for putting the finishing touches on what GM started. Great Job!!!
