On my way in to work last night, I hit the most ridiculously huge raccoon I've ever seen, at a speed of around 50 MPH(not sure of PRECISE speed - 55 zone, had zero time to brake, but was cresting a hill and not hammering the throttle, so definitely udner the limit but not by much), and while the car drives fine and has no visible external damage, underneath is a slightly different story.

As I said the car still drives fine, and I had plenty of time at work(newspaper delivery) to feel it out, so there isn't any discernible mechanical damage(no indication of any fluid leaks), but I now have the following to fix:
1: Busted front air dam(don't know if this is the right term for the part - the piece underneath the front bumper cover that sticks down a couple inches).
2: Driver's side front inner fender pulled out(but seems to be intact)
3: Busted up air intake piping/resonator box.

What I mostly need help with is finding:

1: The proper term for the "air dam" so I can find a replacement.
2: Part number for the specific pins/rivets used to attach the inner fender and aforementioned air dam.
3: Somewhere that sells stock/OEM replacement air intake/resonator boxes.

Yes, I know this has put me in a state where the hard part for installing a cold air intake is already taken care of, but I have no interest in installing a CAI unless there's one that perfectly replciates the job of the resonator box. And won't cost me an arm and a leg. (I'm not after performance and cannot spend without need)

Thanks in advance for any and all help you can provide.

I have to say, though, I did not realize that Civic bodies are carved from solid blocks of granite. Busting up the resonator box, ripping out the inner fender, but NOT LEAVING A SINGLE CRACK, DENT, OR SCRATCH on the body is very impressive.

Upon close inspection I have been able to determine that the air dam is not actually broken - I did not realize it is in three pieces. As with the inner fender, I need only get the pins/rivets to put it back on. (good thing I went back to retrieve it)

I now only need help finding an OEM replacement resonator box.

For the front bumper: https://www.hondaautomotiveparts.com...umper--bumpers

for the intake: https://www.hondaautomotiveparts.com...r-cleaner-1-8l

That site is one of my go-tos for genuine Honda OEM parts. If you don't like their prices (usually the best out there, btw), you can at least get part numbers. Also, one of my local Honda dealerships will price match any online price+shipping I find on an authorized online Honda parts dealer site. My other go-to is www.hondapartsunlimited.com

The first link is no longer needed as it turns out the part was not actually broken.

The second link does not include any of the broken parts.

well, crap. Let me do some digging to find out what you might need

edit2: that's my bad for glancing over your second post. lol

That appears to be it(I'm attaching photos of the broken parts just to cover all bases, though). How much priority should I put on replacing this? I know the resonator isn't JUST about reducing noise, but I see a lot of conflicting info on how important it is to replace if it gets busted.

So....got another issue.... I was looking over the diagram for the resonator box assembly and noticed that one of the pipes is NOT shown amongst any of the parts in the link. I've no idea what it connects to as we have not yet jacked up the car to work on and really look at(that comes tomorrow - I have tonight off), but in the meantime I'd like some info on where to look for potential damage from this coming out. I've obviously attached photos.




This piping appear to be undamaged as far as I can tell, and I cannot find a part number on it.

TBH, resonator isn't quite a vital part. If you don't install it, you'll have a little more engine noise, really about it. Maybe a slightly higher intake air temp since air suction source will be deeper inside the engine bay.

as far as that missing part. No lie, if you look at the entire assembly #7 in the diagram, that missing pipe looks like it snapped off from inside the chamber. The broken plastic box doesn't have the pipes sticking out of it, and the angles of the "pipe missing from the diagram" kinda match the pipes sticking out of the box in the diagram.

Seriously though, that must have been one hell of a chonky boi trash panda you hit dude. Holy crap

edit, because I suck at typing out complete thoughts before I hit submit:

more on the "vitality" of the resonator chamber. Unlike the 10th gen, it doesn't look like the resonator box provides any structural support to the filter housing. In my 10th gen, filter box literally sat on top of the resonator chamber, which then bolted to the chassis. I could be wrong, though, since I've never pulled apart the air intake assembly from an R18

You called it - as soon as I saw your post I went out to check, took me two seconds to find how it fit inside. And now I'm actually thinking it may be possible to piece this back together - if I can find a way to completely seal the box it should work mostly like before - at the very least will provide the potentially cooler air by taking it in further from the engine. It's a question of whether or not it's mounts are broken at that point - need to take a close look at it once it's back in shape. I'm always up for saving a few bucks on parts that won't make the car blow up when you go cheap, so if I can make this work, that's a pretty big benefit.

If I can't piece the box back together, I can at least put that section of piping back in so that the car will get cooler air.

The speed was a big factor, but even accounting for that, "chonky" is putting it mildly. I never even new raccoons could get this big - my dad had to "deal with" one that was threatening our chickens the other day, and it was the biggest one I'd ever seen to that point. It took a lot more than it should have to deal with(tiptoeing around with terminology just to be safe here, but I think you get what I mean). This boi was TWICE the size of that one!

It definitely isn't structural. The only thing that feels loose ANYWHERE in the engine bay is the hose/pipe going into the air filter box, and even that seems to have a mounting point still connected to something else below where I can see from above - this box was definitely mounted to other more firmly connected parts.

I'll be seeing what I can do with this box when we jack it up to put the inner fender and air damn piece on tomorrow. Looks like the worst case scenario is a $42 purchase that I won't need to rush. Thank god for small favors.

I won't be anywhere near the speed limit on that section of road in the future. I never had a hope in hell of seeing the critter before it was too late because of the really tall grass right at the edge of the road.

If it's made of ABS, make you some ABS glue. The way I made some was taking a 87¢ ABS coupler from home Depot, cut it up into small pieces, and put it in a jar of acetone for a couple days. Becomes a slurry you can paint on, and once it dries, it's solid ABS. However, I'm pretty sure these boxes are made of polyethylene or polypropylene, so nothing sticks to these very well.

The box is not fixable - it's too far bent out of shape to be bent back into it's proper shape without some very specific heat treating that is beyond my capabilities. I've put the piping back in place so the engine will at least get cooler air and I can worry about replacing the box itself something down the road. Car is now back together with no visible evidence anything ever happened.

there you go man. Sounds like the best course of action. Like I said, that box isn't vital. It's more of a comfort thing for grannies that don't like to hear their car running

Due to my job(newspaper delivery) I pull up close to a lot of people's houses while they're asleep. Sound control is a BIT more vital to me than most. :P That being said, I could literally hear NO difference after the box fell out, from inside or outside of the car, so I doubt I'm any more likely to wake anyone up.

Oh, yeah, it's not that drastic of a difference. Moreso on the air suction sound side. It's definitely noticeable on my 2018, but that's because the resonator box also attenuates any turbo woosh noises. I wanted woosh noises.

Heh. Just don't be like this guy with your turbo:
(my best friend has a 2017 Impreza, and he HATES it when I bring that up :P )

haha blast from the past video there. the L15B7 turbo is equipped with a recirculating bypass valve, no traditional blow off valve. those that have installed BOVs experienced rich conditions since the tuning takes that recirculated air into account for AFR. No duck call BOV for me
