Swap the OEM airbox for the PRL HVI, reuse the OEM bottom mount and seals, route the MAF harness, then compare induction sound vs stock and the Sprint/Spoon filter. This 10 min guide covers the 2023+ Honda Civic Type R FL5 and Acura Integra Type S DE5 with tools, parts links and the full video.
Overview
A full airbox swap that dumps induction noise into the cabin — louder than stock and louder than a Sprint/Spoon drop-in in the stock box. The PRL box reuses OEM mounts and seals, adds a lower snorkel that feeds straighter than the OEM path, and looks more OEM than a carbon open intake. Power feel is similar on a Stage 1 tune until you load a tune that accounts for the HVI.

Video chapters
Step by step
- 1
Unbox and inspect▶ 0:26
Textured plastic box, smooth interior, coupler, velocity-stack style inlet, hardware and the lower snorkel that feeds the bottom of the box.
- 2
Leave fasteners loose while seating the box▶ 3:46
Don't snug anything until the box is fully seated. Reuse the OEM bottom piece that aligns the drain hole, and the rear mount.
- 3
Route the MAF harness▶ 4:14
The OEM plastic loom that wrapped the stock box is a pain. John pops one pin and routes it along the PRL box instead of removing every clip — easier if you ever swap back to OEM.
Tip: Those clips are brittle; go slow if you fully remove the loom.
- 4
Free the stuck OEM fastener and seat seals▶ 5:18
Factory often peens one fastener so it won't unscrew — loosen the two OEM fasteners and pull the piece straight out instead. Push the OEM seals fully home; they take a firm shove.
- 5
Warm-up sound check▶ 6:30
Warm the car, then compare startup and revs to stock and to the Sprint/Spoon drop-in. Expect more cabin noise on the left side, audible with windows up.
Tip: John runs Honda Data Stage 1 (91) here; he notes a Fairable HVI-specific tune is coming.
- 6
Final thoughts▶ 8:24
Louder than stock and louder than Sprint/Spoon in the OEM box. Power feel is similar until you flash a tune that expects the HVI. Strong recommend if you want intake noise for the price.
Wiring notes
- MAF sensor stays plugged in; only the harness routing changes

0:00What's up guys, it's your boy, John. We are back again here with another video something exciting came in today
0:06It's the PRL HBI intake for the Civic Type R and the Integra Type S
0:12So yeah without further ado, let's do a quick unboxing sound comparisons between the other ones
0:20I did earlier which is stock and then the sprit filter and
0:24Now we'll get my reactions
0:27PRL? Okay, so those poems that expand, we have this plastic molding
0:46the outside is texturized, we have a coupler
0:51and more of that poem, nothing on anything
0:56Look at the meat and potatoes of it, you can see on the insides it's smooth which is great
1:06And while everything's inside of it, this one's gonna screw
1:18this so we can get more access
1:24Notice it's pretty expensive but compared to other intakes on the market, it's a great deal
1:31All right, I'm not into like okay engine bay with carbon fiber, it's awesome
1:38I think there's a fine balance between performance
1:41Looks, I kind of might dig this OEM looks
1:45Heat soap, okay I'm not gonna just leave like that
1:55Now the coupler here in the mouth house, let's do the design, it's like a
2:14velocity stack, PRL printed
2:28Hardware, looks like some washers
2:40Now this is all interesting piece right here, this is a snorkel
2:48for the bottom of the intake, so I haven't seen any really good footage
2:53So imagine the car kind of like this, it's gonna sit like that
2:58And the OEM one
3:01Takes air here, goes down
3:04And goes back up, this one just goes straight in
3:07But even with that change, it's not enough air accordingly
3:27Gonna be cool
3:32Install, there are some good videos out there, I'll see if I will
3:38Do a quick install, but I really want to do just do a comparison
3:42All right, so the box is in, I know it's got a lot of steps, I'm just gonna tell you what I ran into
3:47And some mindful thoughts
3:51When you install the box, try to give this, make this area loose, don't bolt anything that kind of goes without saying
3:58The the bottom right here has a part near reuse from the OEM box that kind
4:04And then there's that drain hole, so there's just one, this one kind of helps align the bottom
4:10And then it reuses this back when right here as well
4:14Now for the mass sensor harness
4:18There's this plastic piece that used to go around the OEM box kind of like this
4:23And it goes here
4:25So that piece is kind of a pain the butt to take off
4:32But you could just remove one of these pins and kind of route it like this
4:37You could take it off, I just left it on there because it kind of just works like that
4:43Um, you can see right there
4:47Taking it off this priority, I mean you just unplug this and take it off one
4:51Just like I feel like 20 little those pop clips
4:55And um
4:57Yeah, I just didn't want to do that in case I need just I live in California, so
5:02It's a pain the butt just in case I need to swap back to the OEM box you just flop it real quick
5:07So I just like I'm not gonna spend like 30 minutes
5:12Maybe you can do it better, but they're plastic, so they're it's easily to break
5:16And let's see what else
5:18This piece right here is normally
5:23It is like they kind of like grind it off so you can't
5:27Unscrew it from the factory
5:29So instead of like unscrewing it just loosen these two OEM ones and then you can just pull it straight out
5:37Um
5:38Yeah, we use OEM seals
5:41These little things are kind of hard to push in but they push in
5:46And uh, yeah, that's about it
5:48I'll go for a test drive give you guys a
5:52Sound comparison. I'll try to make it similar to my original video
5:56I do have the Honda out of tune now, so it's a little bit more aggressive in terms of the pops
6:03But if you can just focus on the startup
6:07So I already started the car just in case
6:10And I've warmed it up set like four barters three bars right now, so
6:14Should be good. It's already warmed up. I'm gonna start it do some revs and then move on to the
6:21My impressions of me driving it. Sound comparison is what you guys are here for. So
6:26I'll try to do a good job
6:28And keeping it pretty
6:30Similar all right, so that concludes it the PRL intake my thoughts on it much louder than stock
8:32It is louder than the OEM
8:35Stock box with the sprint and spoon filter
8:40And I definitely hear it more towards the less side of the car
8:46You can hear it with the windows actually up now like a good amount
8:52Um, power wise it feels
8:55Okay, like the same to be honest
8:57I actually have a fairable tune that has it for the intake each
9:02HVI for the PRL intake so I have a tune for it
9:06I need to put on and you know
9:09Shout out to John Vega for that. That's gonna be an upcoming video of having it all that
9:15Jazz going on right now. Just have the Honda data stage one tune the 91 octane. So yeah
9:22Overall do I recommend it?
9:25For the price and if you're into all this stuff and if you like intake noises
9:29I think you'll love it
9:31Yeah, thank you guys for watching. I'll catch you guys in the next one peace out PRL intake. It's a dub
