11 Attachment(s)
My JDM CR-Z Mugen AirBox just arrived today,
hopefully I can install this soon. It basically DOUBLE the Filter area of the CR-Z AirBox that I currently had on my Honda Fit. It will also connect to the CR-Z OEM Snorkel to inhale cold air from near the grill. It came with K&N Air Filter. I bought this because I plan to tune it TOGETHER with the Sprintex Supercharger so I don't have to retune it later. Now, I really need to save money to get Sprintex... The Box: https://www.fitfreak.net/forums/atta...ine=1448091236 https://www.fitfreak.net/forums/atta...ine=1448091236 Very Nice Packaging: https://www.fitfreak.net/forums/atta...ine=1448091236 All Parts: https://www.fitfreak.net/forums/atta...ine=1448091236 Beautiful Carbon Fiber: https://www.fitfreak.net/forums/atta...ine=1448091236 Came with Mugen Sticker for the Carbon Fiber Cover: https://www.fitfreak.net/forums/atta...ine=1448091236 It have internal Velocity Stack??? https://www.fitfreak.net/forums/atta...ine=1448091236 The Airbox from FRP: https://www.fitfreak.net/forums/atta...ine=1448091236 K&N Air Filter which basically have double the length of standard CR-Z filter: https://www.fitfreak.net/forums/atta...ine=1448091236 For comparison purpose, this the the OEM Stock CR-Z AirBox with K&N filter that currently installed on my car (and will be for sale soon :) ) Notice the different in Air Filter size: https://www.fitfreak.net/forums/atta...ine=1448091236 Another pictures of the AirBox (FRP): https://www.fitfreak.net/forums/atta...ine=1448091236 Now, I hope there is no surprise and I can install this Mugen AirBox without any modification to the Honda Fit... We will know by next week when I have my day off and time to install them :) |

What do you mean by better?
|
I wonder why the carbon fiber part is just a beauty cover? It should be the lid of the unit.
But it looks a lot like the stock one on my 330 BMW.. interesting.. |
its cheaper to mold a "beautiful" cover from carbon fiber rather than integrate it into a structural air box.
|
Function + ;)
|
I plan to install this tomorrow, will update here :)

I just install The AirBox:
Start by taking out the Air Sensor and then the rest of the AirBox: https://www.fitfreak.net/forums/atta...ine=1448586671 Moving all the Rubber Pieces from the OEM CR-Z Airbox to The Mugen, and applying some silicone lubricant to make it easier for the rubber to slide into the holes on The Mugen AirBox: https://www.fitfreak.net/forums/atta...ine=1448586671 https://www.fitfreak.net/forums/atta...ine=1448586671 Before installing the Air Sensor have to install 2 bolts below where the air sensor suppose to go. apparently this AirBox was designed by Mugen with something different for the Air Sensor... so there is 2 holes that need to be plug by 2 bolts that don't really hold anything, just plug the holes, and I point it with my finger: https://www.fitfreak.net/forums/atta...ine=1448586671 All Rubber Parts and Air Sensor Installed: https://www.fitfreak.net/forums/atta...ine=1448586671 Side by side comparison between the OEM K&N Air Filter vs. The Mugen K&N Air Filter, exactly double the size: https://www.fitfreak.net/forums/atta...ine=1448586671 With this airbox, you got to install the air filter, the upper cover and the carbon fiber cover OUTSIDE the engine bay, cause once it is inside the engine bay, you don't have space to install the carbon fiber cover or the airbox cover... yes... the space is tight...: https://www.fitfreak.net/forums/atta...ine=1448586671 https://www.fitfreak.net/forums/atta...ine=1448586671 Problem with using CR-Z Airbox is, the battery really tight with the airbox, infact to remove or install the airbox, the battery need to be remove, for sure there is noway to use the 51R battery, have to use the original size battery... even that still tight... and this Mugen Airbox is tighter then the CR-Z airbox in relation to the battery, I will need to trim it later when I install it with Sprintex Supercharger :) Oh, did I mention, I just ordered the Sprintex and paid it today ? :) Hopefully it arrive soon... The bolts were not aligned too so I just use tie lock and on the right side it don't even have any bolts, but it is resting on top of the bracket so it aint going anywhere, I just need to get longer bolt soon... https://www.fitfreak.net/forums/atta...ine=1448586671 https://www.fitfreak.net/forums/atta...ine=1448586671 so after plug back the Air Sensor Electric Socket, and tightened the connection to the intake hose and throttle body and also plug in the Crankase breather... I then clean the carbon fiber cover with alcohol and apply the included MUGEN Sticker... I start the car and it sound quiet.. I am too tired to test drive and going to have lunch first. will report back later after I test drive the car tonight... Here is after installed... hmmm... It do looks nice hahaha :) https://www.fitfreak.net/forums/atta...ine=1448586671 https://www.fitfreak.net/forums/atta...ine=1448586671 https://www.fitfreak.net/forums/atta...ine=1448586671 https://www.fitfreak.net/forums/atta...ine=1448586671 https://www.fitfreak.net/forums/atta...ine=1448586671 |

Thanks, and Yes, I actually ordered RDX Injector early in the morning yesterday before I order the Sprintex... I took advantage of Bernardi Honda and Acura Free Shipping sales... Well, I wasn't planning on buying the Sprintex until I saw GREAT TIPS from JibberJabbs at Sprintex Thread about the great discount on Sprintex Kit, and I can't hold it anymore, hahaha... I am still undecided whether to use AEM F/IC-6 or KTuner... I already contact KTuner to get more info and he had replied... I also already contact TurboGixxer and VitViper, but both of them have not respond... (well this is ThanksGiving hahaha)... I also contact another poster here that use AEM about possibility of me buying his base map so I can drive the car with AEM to be dynotune... so I am still undecided... Oh, back to the Mugen Intake... So on the first test drive... It was scary because the car is shutting down every few seconds... turn out, the positive battery went loose because the Mugen AirBox were touching... well not just touching but really pressing the battery terminal and push it loose... luckily I manage to limp home... (it happened on the freeway near my home)... back to drawing board... I take out the Mugen AirBox and grind the part of Airbox that touch the positive battery terminal... oh I also grind the left side mounting to allow the airbox to move closer to the engine and further from the positive battery terminal... it is quite scary to dremel the carbon fiber... I worry I might scratch it... well I manage to do it safely :) here are the pictures: https://www.fitfreak.net/forums/atta...ine=1448605323 https://www.fitfreak.net/forums/atta...ine=1448605323 https://www.fitfreak.net/forums/atta...ine=1448605323 https://www.fitfreak.net/forums/atta...ine=1448605323 then install everything back and TEST DRIVE AGAIN :vtec: |
u are a brave man to dremel a perfectly fine carbon piece. now your job is not done breaking into the carbon fiber weave. u need to get some clear coat epoxy resin and you need to wet the exposed fibers to reseal them. otherwise moisture will get inside the fabric and destroy your mugen piece.

Ok, The second test drive is AMAZING...
The CR-Z Airbox (with K&N) was better than the Fit Airbox in term of immediate response from lower rpm to mid rpm and feel about the same at high rpm. The CR-Z Airbox also manage to maintain lower intake temperature compare to Fit Airbox, I notice this because I use Scangauge full time and set the gauge to intake temperatur... I guess the CR-Z Airbox had the advantage of that snorkel intake near the grill compare to Fit who had to inhale air from inside the engine compartment... Now the Mugen AirBox... it had even better response at low rpm compare to OEM CR-Z, torque fell solid at mid rpm, and at freeway speed over 50mph, it feel like it had the RAM AIR EFFECT !!! I guess that snorkel combine with the much larger K&N filter inside the Mugen allow it to have little RAM Air Effect... oh don't forget the design of Mugen Airbox is much more direct without the labyrinth of factory Honda... Now, what is STRANGE is the INTAKE NOISE of the Mugen is actually MUCH LOWER/Quiter compare to the CR-Z Airbox with K&N air filter... on the other hand, on the over run, my car now had that little back fire sound hahaha yes, exciting... back fire when I abruptly rev the throttle and close it again... Can't wait to get my custom 2 1/4 exhaust installed I already had the OEM Civic Si Resonator and Muffler since few months ago... Just don't have time to go to custom exhaust shop yet... Once that done, then I can decide KTuner or AEM F/IC-6 and then install the Sprintex... :) |
