I am the perfect person to ask as I have run
Injen
Bms
Agency Power
Before JT (I’m a bit crazy

First all the above do great and add responsiveness over stock!
Agency power, AEM, any all plastic has less heat soak and are my favorite in that respect
BMS looks cleaner, has partial heat shield and is hands down one of the best for affordability
Injen is great, one of best looking for mass produced intake but pricey
all above had no noticeable difference in performance, testing temperatures the all plastic did best
BMS better than
Injen
For the price
Injen should have a heat shield.
I installed the JT with assumption it would perform same, I was shocked the first morning and immediately pulled a couple runs as I thought I felt more tq.
using odbii reader with gages I posted 16 more lbs of tq than I did with any of the ones above. I spoke with two owners that just got their JT in, both replacing an
Injen and a agency power, both said they felt more power. We all also added the merge pipe which is larger as well.
ID on JT intake is 1/2 inch wider, the filters are much bigger, and the closed box design really gets air moving around for those filters.
I paid full price for my JT, I did not get a discount to push them! I get a small handling fee for taking the group order and reshooting to save everyone money.
Any intake is loads better than the stock, these are just on a level all their own!
