Figured I'd share my red-neck attempt at blocking off the open space the JLT kit creates. Not sure why they didn't spend the extra time to close this area off but assume they did it for ease of install/maintenance reasons.

No clue how effective it may be but figured I'd give something a try since I had some plastic left over from a previous project and that gap was tugging at my OCD strings. After taking the air vent off the hood and measuring the gap I found the gap was actually much larger than I expected. The JLT kit has the weatherstripping on the top by the engine but it's every bit of 2 inches from the hood. That gap goes almost halfway to the middle of the coolant degas tank to the other side of the intake tube. As such I decided to fill that space as well as originally I thought I'd only need to solve for the part above the tube. The after now has the intake sealed to the hood all the way around until the right side (again where the degas bottle is located) but that area is pretty close to the hood and is right below the hood air vent so I didn't worry about that spot.

I wanted to be able to remove it down the road for maintenance as well as if I decided I didn't like it so I drilled two mounting holes in the middle of the ledge the weather stripping goes over and used two nuts, bolts, washers and lock washers. I also painted the hardware to help it not stick out like a soar thumb. Not the best looking contraption but it came out good for my skill level.

Damn good job Frosty, looks great and certainly couldn't hurt, that's for sure. Love the blue filter as well, not available any longer it seems. I've been looking...

That's me with the LMI with jlt box. I just started doing this same exact thing with textured black plastic with the seal across the top.

On the '19+ Hellcats, that JLT seals against the factory hood duct to create a seal.
I have a 2015 with a power steering pump, so 19+ will not fit on my car.

Is yours a redeye? Anyway to get some detailed instructions? Another pic?
I have a 2015, they didn't make redeyes then.
The next time the car is down off the lift with the cover off, I can take detailed pics.

I didn’t have to modify anything. I would assume you want 19+ box. Mines a 15 so I can’t say for sure.
A 2015 box has the indent for a power steering pump, 2019+ has electric power steering and no pump, no indent and will not fit on older models.

what did you use for the weather-strip extension?
I used the existing seal that goes under the tube and went over the top with it. I bought this and put it around the tube.

Same as green machine. I used the existing seal that went around the tube and ran it across the top. I've been looking at something to now go around the tube so will try what he just posted too.
