I have a 2018+ JLT CAI on my 2017 and plan to seal it. I have thought about a couple of different ways but was wondering for those who have done it, how did you go about it? Preferably looking for non OEM GT350 boxes since that is pretty simple and have seen several of them. Thanks!

I did one for my JLT. Fti
On track..is useless. Temps were the same.real only advantage is at the light.
If rain is a concern..JLT does a water-resistant mesh to cover the filter :)
Yup I keep the pre filter in my driver door. Been using it for years. Was just wondering if there is any real benefit. I remember you doing it a while back but wasn't sure if you kept the close set up or not. Thanks for the feedback!
