Description

DOES NOT WORK WITH THE VIS VENTED HOOD!
+15whp +19wtq mid range without tuning. Even more power with tuning! Comes with all new bolts.
This manifold riser extends the length of the intake runners which allows the air flow more time to reach optimal velocity in the mid rpm range which in turn increases mid-range torque output which these 3.8’s really need! Additionally, it extends the torque curve to continue producing torque further up the RPM range. With a custom tune, the peak power is shifted higher in the RPM range. All of this means greatly improved performance from your V6!
 
This raises up your manifold, your intake may need adjusting, you will not be able to use your engine cover any more and you will need to either do a coolant bypass on the tb, or extend the coolant hoses going to the tb.
Using a phenolic spacer is NOT recommended as it may cause clearance issues with the stock hood.
Note: If you’re canned tune, you will need a custom tune. If you’re custom tuned, you will need a retune!
