Comander 3.7 compatibility with Liberty 3.7?

There's a lack of V6 Commander performance parts out there and I'm wondering for such things as throttle bodies, Throttle body spacers, cold air intakes, etc, is there compatibility with the Liberty 3.7? The Liberty has been out long enough that all of these things exist for it, so would they work on a Commander V6?

I think the reason for that is because if you wanted performance you weren't going to buy a 5,000 Commander with a 210hp engine

I don't think you're going to see much stuff in the way of performance specifically for Commanders as theres a limited amount of them and they probably aren't going to be produced for much longer...

If you're looking for something like a exhaust or what not you could always just go to a local exhaust shop and have them fab something up for you...

The stock equipment has a decent flow rate, so with mods the only benefit for the V6 would be at the top of the RPM range at wide-open throttle. Anything less and the stock components can perform just as well.

But how frequently do you accelerate with wide-open-throttle all the way to redline? Even then, you don't know if there's a benefit without dyno'ing it, since the benefit would probably be very few horsepower, if any.

Anyone who has done a lot of mods while using a dyno to test the real results can tell you that any mod may have no effect at all, or can actually reduce power -- regardless of what the seat-of-the-pants impression is.

And even if you did gain the benefit, you'd have to put up with increased exhaust drone in the cabin all the time for a benefit that you'd only have on rare occasions of maximum acceleration to redline.

You really have the best combination of performance and cabin quietness that the engineers could come up with for a V6. I would enjoy it as it is.
