it was to be expected. Theres no way these minor upgrades (rad + grille) were going to somehow stop a car overheating badly for those who tracked their cars.
Don’t do this to there are very good reason not one single car manufacturer does coolant flow through rad hoses this way. And slight loss I coolant the reverse flow will pump air through the cooling system. Instead of channeling air to the bleeder hoses built into the system you now pump air to the bottom of the radiator. Also if the car comes close to overheating the boiling coolant will not longer go to the top of radiator but get stuck cause water pumps can’t pump air downward. Another reason not to do this is the secondary coolant sensor to turn the fans on earlier. Half the radiator still ha colder coolant in it. This is an ineffecient way to cool. You’ll burn up you rad fans running them non stop unless you tune the fans to run off the primary sensor and not the secondary sensor. Plus you now pull coolant from the top of the radiator and cause heat tends to go up you get inconsistent temp control. By pumping from the top down through a radiator allows more time equalize temp across the rad having greater cooling efficiency. That’s what the factory routing is that way. The only thing your doing is turning the fans on earlier: that’s where the temp difference is coming from.
The reason for delete of upper opening was to increase lost downforce on the front. It’s utterly stupid and unless your doing over 100. The front splitter is also changed. The stocky two grilles on the market that improve significantly is the pro civic grille and j’s racing. The Evs one looks cool but being the air coming hits a sharp edge through the kidney bean cut out it tends to tumble in place and doesn’t improve that much. You need smoother transitions. J’s Racibgchas easily the highest improvement but costs is stupid at 700. The pro civic grille is 180 and there is a copy cat grille on amazon for 130.
I mean, that sounds good and all but without any real evidence Im going to be very speculative. Simply put, I don’t believe any of it. Moving a slot in the grill down 3.5 inches will not do much at all, regardless of what Honda May claim. They’re marketing the “improvements“ so people will buy. I’m also guessing you didn’t put the car into a wind tunnel and do testing, so again... I don’t believe the claims.
Hi bro any part numbers these for 2020 type?they actually didn't redo the front "splitter". At least what most of us here would call a splitter. Their wording was confusing.
they just messed with the rubber flap thing on the bottom of the bumper/undertray lol.
as you can see its deeper on the end and has like an air deflection on the end
Do you have part numbers for them?they actually didn't redo the front "splitter". At least what most of us here would call a splitter. Their wording was confusing.

i dont know off the top of my head. Should be there on any online ordering site like hondapartsnow though.
Hondaparts now doesn't have a searchable catalog for 2020 parts.

When they released the reverse design I was intrigued by it. Russell Garehan, one of the Acuity managers is a Mechanical Engineer with years of experience in heat exchanger design especially in the high performance automotive industry. My money is on him designing something that won't damage our cars. He also did design work for Hybrid years back. At the end of the day though is a 2°C temp reduction even worth it when the page claims you need the other upgrades too? IMHO probably not.
