Eventuri Hybrid Airbox

[Slideways]

If you are having trouble removing it from the intake manifold, you could also reach down and disconnect it from the oil pan. It has a press connector similar to the air shut off line on the airbox.

After you remove it once from either side, it becomes much easier the second time.

What was your method for that hose? Did you reach in and unclip it from inside the old air box? I pinched the tabs while pressing down. It’s a tricky one to get back in too — you have to reach in from the front with the box lifted and snap it in

Yea it was a painful one. I didn’t know it was down there when removing the old airbox so I stretched it pretty good u til I noticed the pull, then reached under to unclip and probably compromised the plastic at that point. New one I took a while to get it installed with no airbox in there and then clipped into the carbon box before putting throttle bodies to the box so it had a little bit or rear tilt to allow me to blindly get it plugged in. Pretty rough took me 30 minutes. Glad I did it though.

I fought the internal battle of continuing regardless or stopping to order a new hose from FCP to do it right. Install temporarily paused due to this hose issue under the box.

Got new hose and will update with final install pics soon, !

Those that have installed, what are you doing about the dipstick?

The airbox has a nice bracket that clamps it and holds snug with pressure around the dipstick and a foam cushion so it does’t slap around.

Care to share the part# for the lower hose you replaced. I'll pull one in before my install just in case

Yea could be worth doing as mine was dry rotted and brittle. I also did the throttle actuator that’s under the airbox and the CPV hoses same time while I was in there.

Quality appears 10/10, and carbon is thin and feels very delicate. I have not touched a typical CSL style carbon box in person for comparison, however. Spent time to install but brittle plastic hose connectors broke and I fought the internal battle of continuing regardless or stopping to order a new hose from FCP to do it right. Install temporarily paused due to this hose issue under the box.

Got new hose and will update with final install pics soon, hopefully over the weekend. While I was in there I ordered all new fasteners and screws for the fan shroud and plastic bits so it's all accounted for. Stay tuned!

Any chance you can do a sound clip?

I'll try to get one going - it definitely sounds different than the IG videos from Eventuri.

Happy to see these finally arrive, looks good. I have this on my list.

Apologies for the delay; here is a quick picture I snapped.

Overall, driveability is as smooth as OEM which is a huge factor for me. I had the Karb csl style airbox previously installed and ultimately had to swap it back out because I never dialed it in right for city / low RPM driving.

From a sound perspective, the note is fuller than the intake alone. I would analogize it as 1) eventuri intake - trumpet; 2) hybrid airbox trombone; 3) karbonius csl style airbox tuba.

The Karb is definitely has more bass resonance at lower rpm 3-4k / and wails equally as loud at 6-8k rpm with slightly lower tone. However, it always felt and sounded a bit gimmicky to me since I didn’t have the rest of the exhaust done.

The hybrid does a good job of giving a bit more fullness due to the carbon resonance while still feeling very OEM+. My guess is the Karb OEM box sounds similar. This package aesthetically looks more uniform and complete.

Happy driving!

Any issues with the strut bar?

No issues plenty of clearance.

Hopefully this is more durable than their earlier CSL boxes. Holy crap...Evolve used some not so sturdy mountings on those.

I'd be scared of any place that has a fastener glued in. If the part requires internal threads then a knurled insert should be molded into the part. This also makes part production much harder and more costly - even with prepreg.

I think the trumpet mounting makes a lot of sense.

My copy just arrived. FCP Euro fulfilled order quickly. Late March estimate for install. I'll share install notes as others are already contributing. Stoked!
