stock airbox

You guys test stock vs aftermarket?
Or stock vs modded stock? On mine
93 tune stock air box vs 93 tune with
my JLT the JLT was .25 seconds quicker
On average.

How much positive pressure can the stock box possibly produce? I would think the airflow would stall way before at sort of "boost" is seen.

Without a MAP sensor it is not easy to figure out.

Tap in a digital boost pressure gauge into the airbox. Atmospheric is 14.7lbs/ square inch. 14.8lbs would be positive pressure.

Do you have any idea how lazy I am? Ideally would probably want it in the manifold.

You'd want it before the TB you know.. for scientific accuracy
And I'm prolly as lazy :lol:

So does the 2018 stock air intake assembly fit well in the previous years from 15 to 17 I have 2017 GT but just a little worried that the assembly wont fit because of the 2018 bumber facelift so I think the air duct sits a little differently in 2018 and won't fit in a 2017???
