Best Cold Air Intake kit to get for 2021 3.5 EcoBoost 6 cyl?

[Mtnman1]

Yeah - I decided not to put one in after all. It was a great improvement when I put one in my 1997 Grand Cherokee (inline 6), along with a bigger throttle body, header, custom exhaust, ECM tune, etc.

None of that stuff for the Powerboost. 3 years on, and it's still stock.

The larger throttle body and tune was most likely 99% of your power gains.

If You want real power gains, a tune for the 3.5 turbo is well worth the $$$
