My 2001 2.7l Box is also on the IPD Plenum with the 74mm TB. And I love it too. The throttle response is much quicker. It would also be believeable (from seat of the pants feel) that it produces more hp, but I've never dynoed the car.

An interesting side effect of installing the IPD Plenum is that the intake roar is very much enhanced.... Granted, I also installed a BMC drop in filter at the same time as the IPD Plenum install, but the roar of the intake is very very much enhanced. Partly due to the deletion of the resonance box (replaced with the IPD silicon piping), the BMC filter and larger TB (??). And I still have my snorkel in place !! Wonder how it'll sound without the snorkel !

In fact as I still have the stock exhaust system, the main "entertainment" when I'm pushing the car is from the intake roar (not the washing machine sounding exhaust - haha).
