FL5 27Won hybrid intake: initial impression

[Mawfuqqa]

What people probably want to know vs everything below: The sound is excellent! No cel. Can hear it windows up or windows down and over music at my regular listening volume. See/hear some short clips at end of post.

Issues I've ran into: Could be personal or both myself and product.
- 3d printed MAF housing gasket was too thick at 3.0mm to really squish on, I also think I sprained my lower back at some point... (old man) The instructions state to press hard on the elbow and MAF housing to seat it/lock it in. I should not have but filed at the elbow tab a little bit to twist/lock to no avail. I think the problem is not enough give in the gasket or I'm too old and weak. Gave up and just seated the housing/elbow without the gasket to drive home. Seated without the gasket it's loosely twistable but didn't budge on my drive home last night/this morning. I may heat gun the gasket sometime today and try again.
- My cousin states 3d printed gaskets shouldn't be an issue for the heat. He's going to make me various gaskets from 1.5mm incrementally by .1 up to 2.8mm. Said whatever ABS/TPU material he is using can handle 160-240F. I would assume the 27Won provided gaskets is more or less the same or better heat resistance. Will also see if the local hardware store today has some rubber/silicone rings in similar dimension.

79.31 fits correct

4.5 fits correct

3 in question as mentioned

These are minor and I would not fault the product, just some things to note.
- My shroud required loosening some of the existing hardware to seat the plates closer to personal desire.
- The rubber stripping was a little pita to install. Encouraged it with a heat gun and pried it about with a flat head. There are some pinching at the corners to be expected. Otherwise fully seated as much as possible with no metal showing except for one flat edge after rounding a corner doesn't want to stay full seated but I reckon hood closed should not be an issue; just slightly raised off not gripping the metal entirely like hovering ever so slightly above it. When seating flush on one side the other end is too long by about 5mm, left it as is.

Overhang (Does not appear to be a problem)

Pinch (likely normal due to nature of material/fit)

Slightly raised off the metal after rounding the corner. I don't imagine it would be an issue.

- Do not lose the black spacer, I almost lost it though can probably craft or find a replacement at a hardware store. It's for the step regarding relocating ECU. Kind of finicky position if you don't have small enough / dexterous hands and fingers. We all know to not lose any nuts/screws but from the looks of it easy enough to find replacements for but the black spacer would've been more of a pain.

- The pdf file link pictures are blurry or at least for my old eyes they were difficult. The dozuki app had much better picture quality but my old eyes find it annoying to view the phone over a monitor. Otherwise seemingly good instructions/pictures.

Things I'm unsure of:
- The 3d printed MAF housing gasket reliability/durability. It is stated to replace every so often but unsure of what mileage milestones and etc.
- The rest of the fitment as I'm not finished.

I stopped after step 15ish and just cobbled it together to drive home as it was getting late and cold as hell. Here are some videos as of this morning just because I wanted to hear it.

Did not go WOT incase of anything funky due to no gasket and 100% not fitted correctly.

12/10 I hit the provided gasket with a heat gun and was able to get the maf housing to the elbow. In hindsight should've tried that to begin with given it was near freezing temps. Also should've gave it more heat as i think it cooled off as I was twisting it on and now it's stuck in position so it'll be fine. Adding few more videos

Exterior sound: Quick sound

On the freeway: Listening to boost. Oddly enough the boost sounds way more prominent listening to it off the phone video/speakers. 6th gear in comfort.

Wow that’s sounds great dude. Any chance U can update us after a while on your intake temps?

 

[Mawfuqqa]

The sound is indeed!
Will keep an eye on the iat over weeks/months. Hoping to get the gaskets from my cousin sometime following week and finish the install.

Couple more sound clips from the morning. engine r+, ~30% throttle, dual resonator delete.

Sounds really good

 

[Mawfuqqa]

Sound with the hood open / closed



Even this short file in 1080p was too long to upload. Will have more videos up via yt channel eventually.

Thank you so much for this. You're the only person I've seen with a review/install.

@Vlad@27WON can hopefully help answer/address the issues you saw.

How much louder is it over stock? Can you get any drive by videos please?

I'm pretty sure me and OP spoke this week!

No problem, just doing my part. Was originally going K&N. Then I found this and the 3 part blog convinced me. Claims no tune required and won't mess with fuel trim. I don't have a way to test but I'll take their word for it.
I just drove with some buddies for a few hours. Sounds amazing. I would say the sound is about more than double stock.

It could be a combination of user error and cold weather. I didn't have a heat gun at the time but as edited in OP. Next day heating the gasket helped significantly. They do state getting the maf housing to the elbow is difficult but damn lol

Will try to get some drive by videos soon

Thank you it sounds amazing! I had the 27won on my Si and they may quality stuff. That 3d printed gasket is odd/interesting.

Can you please get us a drive by video from outside?

How do you like it now with the res delete?

You did the right thing and many people forget, some intakes were causing issues on the 10th gen civic. Injen was definitely a culprit with changing fuel trims.

This is closest I got right now. Can hear it from the rear of the car.
Lately been driving mostly in comfort because the intake grunt up front and the whoosh is more pronounced with the exhaust going through the 2 side canisters. Good blend of all 3 sounds

This intake isn’t a direct fit? What you are trying to say on relocation of the ECU? Also the gasket you mentioned goes inside the cone filter and attached to the MAF cone? This is the same fitment issue as their exhaust that protrudes from the bumper way too much but you aren’t allowed to say nothing negative? Are difference on any temperature drop regarding this intake? Or is just noise?

I heard a rumor they were working on updating exhaust not protruding?

Ive always bought their products but they needed better testers/market research. The exhaust sounds awesome from videos I've seen.

That and Anita fire their social media video editing team, the obsession of mixing music over intake/exhaust audio... Every single company except AWE and Remark to name a few have just raw sound. No stupid music or talking.

That’s the thing, isn’t it? Too many American companies that offer products to this platform don’t even back up their product just offer a overpriced part just because. The ones that do are overpriced and overhyped, like the Japanese ones. Probably I get crushed for this, but that’s what I think. There aren’t too many that really take it into the chin, but I don’t want to tarnish the post of the OP, but it is a legitimate concern that you pay for something to have fitment issues or something and just accept it like it is something normal. More like with the way money goes nowadays, but sometimes at the end, most companies are for making money at the end of the day, and I understand it, but I could be wrong, but that’s just me. At the end of the day, we live in a free country, and everyone spends their money however they feel entitled to do it. That’s the thing, isn’t it?

Relocating the ECU is because the entire unit is big enough to take up that space. It took a couple minutes, doesn't take long and nothing gets funky. My main issue was twisting the MAF housing into the intake elbow because of how thick the provided gasket is. With a quick heat gun passes on the gasket it was managed.
