Cold air intake. Stock or aftermarket?

[philipchai]

18+ manifold and intake is actually very efficient at making power compared to previous years.

Also majority CAI are now closed box like stock, not like open box before for those V6...

This sounds like a good plan!

I would go dry flow air filter, remove carbon trap, E85 tune. That will net you the most bang for your buck.

Kohr Motorsports Mustang GT4.. if the stock airbox is good enough for them, it's more than good enough for me.

Would the stock 2018 air box assembly fit in a 2017 gt?

Yes it fits perfectly, you will need a tune.

I tried a CAI and the stock 2018 (I have a 2018 GT Premium). I did install a dry flow air filter in the stock unit. I could tell no seat of the pants difference.

However, in stop and go traffic the CAI inlet temps would rise rapidly, 10 degrees per minute on a 90 degree day.

I reinstalled the stock assembly and the temps would rise about 2 - 3 degrees per minute. Huge difference in this regard.

Cold air intakes do make a difference. With these modern mustangs, it's getting harder and harder make better flowing intakes but they still manage to squeeze more than what OEM offers. It's the aftermarket tuning that truly makes the difference. The aftermarket intake system serves to compliment the more demanding tuning.

I have a 2019 GT/PP1. On my 11 and 15 i had the JLT cold air intake installed. I have read the 18/19 stock air box works as while or in some cases better. Is this true? what HP and torque gains would i see with just a custom tune only?

PMAS or JLT intakes are the way to go along with a tune to company them. Great gains to be had with those combos. We sell them here at www.lethalperformance.com
