There was recently a thread about a lift kit not fitting on a 2017 LE due to the deflector behind the radiator. After a little research I ordered the 2017 Radiator air deflector this past weekend. The parts are #12 19071-HL4-F00 PLATE, AIR GUIDE and #13 19072-HL4-F00 RUBBER, AIR GUIDE. I think this should help reduce some of the hot air from the radiator going through the dash.

At my dealer this was around $12 in parts. They will have to look up the 2017 LE as it has them installed from the factory. It's possible all late 2017 models have them but I have only seen the LE. Here it is on the LE

Here's how the install went. Remove the whole under hood

New parts. I skipped the Honda fasteners and drilled the holes out for a 5/16 push pin

Test fit. I used the left (driver's side) most hole as a reference point to the 2017 frame drawing

Drilling holes, a total pain
