Has anyone ever actually managed to get the filter out as the manual says to? Meaning, unclip the sensor thing, unclip the two clamps, open up the box and pull it out?

I've read the idea of pulling the whole box out, but I'm terrified of losing the grommets into the fans as people said.

Am I just wasting my time trying to do it as the manual says? I can get it open almost enough, but not quite enough to pull it out.

someone posted a video at one point.

it's a bitch.

It's impossible to get the filter out the way the owner's manual describes.

The video is linked in post #9 of this thread.

Don't be terrified. It's really easy to unseat the box once you've done it once (finding the right angle the first time is tough.) Do it in a warm area if possible (so the plastic isn't too hard) and just push.

You need to use your caveman strength to push the airbox back far enough to lift it up and out. No being timid.

Another point, the rubber grommets that the bottom of the air box seats on are very soft and can easily be pushed through their holes, where they fall onto the radiator and can jam the cooling fans. I pushed both mine through in pretty short order (they didn't jam the fans, but I've heard of other people who had problems). If you haven't lost the grommets yet, swap the ones on the air box tray for the grommets for the engine cover. The engine cover grommets are much stiffer and won't push through the holes.

i just did this this afternoon it took a lot of careful pushing, and the air box top will hinge open just enough to clear the filter. then the trick is to get a good enough grip on the filter and slip/pull it out really quickly. it took me several tries. i replaced it w/ the the k&n panel filter, which is thinner than the stock paper one, hence easier to go in. don't forget to clip the sensor back

i also didn't like to lift the whole thing up. my luck, i know i'd drop those grommets

Hmmm, I'll try again then! Was it a matter of strength? Or of finesse/wiggling to open it up enough? I mean I don't think I can pull/push/pry any harder than I did, but if it's a matter of wiggling it juuuuust right... maybe there's a chance for me still

AAChaoshand

just take the whole assembly out, way easier

REsuperD

it's *finesse* and wiggling. you can push the accordion'd part of the tubing straight in a little to help, but basically you jam open the top of the airbox just enough and long enough to pull out the filter. this can be done, 'cuz i just did it this afternoon but if it still doesn't work, it might be worth it to just remove the airbox per the previous instructions

Quick question I am only getting 180km to a full tank of gas all city driving would a dirty cause this such low km per tank?

Its an 05 rx8 and has about 39800 kilometres

Let me know thanks

CyberPitz

A dirty intake wouldn't help anything, that's for sure...but I doubt it's the source of your problems.

What a PITA that airbox is. I've watched the video over and over and cannot get the thing out. A friend of mine has an RX-8 so I will have to visit him so I can be shown once. I can't get the posts on the bottom to pop out. I can free the ones in the front, but not enough for the whole airbox to lift out.

This is a good warning! One of my lower grommets came out and luckily fell through to the garage floor.

The video was very helpful, thanks. But, unlike in the video, on some cars there is also a rubber hose with metal tubes that are routed over the front of the air box inlet. This can be removed, but the plastic mount that hose goes through cannot be removed. Makes this job much more difficult.

The video was a great help - who knew you had to take the whole thing out? But honestly, once I figured that out, it was pretty easy. The manual could be *much* more instructive on how to do this. It claims the box will just open up once you get the front clips off - fail.

i just changed my air filter to a pro dry filter. i was getting around 13-16mpg and my factory filter was filthy! i just got the car and im wondering what kind of mpg others get. i did notice a small power increase on this change.

robrecht

Mileage varies wildly among owners based on driving style, amount of city driving, condition of coils, etc. EPA estimates are 16/22. I've averaged 19 mpg over the past 16k miles, with almost no city or Interstate driving. When I do drive on the Interstate, best I've ever done is 26-28 mpg on three tanks and very conservative driving at 65 mph. Best I've ever seen here was 29 mpg, but any mileage calculations based on a few tankfulls is not necessarily very accurate. Lots of previous threads on this if you want to read further.

Hah! I figured out how to get it out without pulling the whole box off. It's STILL not easy, but even a weakling like me managed it.

The trick is to stand by the left tire, and reach forward with your right hand and pull the lid up and back towards you (instead of pushing it up while standing in front of it). I guess it gives more leverage, and my fingers/hands don't get in the way. And the left hand is free to grab it and wiggle it out.

Anyways, it worked for me

Exactly. First push the air box straight back to collapse the corrigated tube somewhat, clearing the front coupling, and then you can rotate the front of the box up out of its snap-in grommets (similar to engine cover). Once all four grommets are cleared there's enough room to slip a short 2x4 under the box so you can open the box without it falling back down. btw: the grommets for the engine cover are better (more substantial) than those for the air box if you lose one (I got a couple spares from Rosenthal Mazda).

It's hard to do the first time as the tubing and grommets are stiff, but easier thereafter.

I just took off the whole piping and everything from the TB to the box....makes it alot easier just a pipe clamp

machfive

If I had watched this video first, I would have definitely given the Mazda dealer the extra $20.00 they wanted to do this. What an idiotic engineering design. If anyone in the SOCAL area wants to make a quick $20.00 and is within 20 miles of Manhattan Beach, post a reply & I'll come to your location with my new filter.

^ Oh come on now. Just do this (reply above):

First push the air box straight back to collapse the corrugated tube somewhat, clearing the front coupling, and then you can rotate the front of the box up out of its snap-in grommets (similar to engine cover).

The best thing to do is keep the clips in the front fastened and pull up on the back of the box to get the back 2 bottom nipples out of the rubber grommets. Then push back on the front of the air box to get the top front nipples out of their rubber grommets. then you can unclap those metal clips to get the air filter out.

before you put it back make sure the rubber grommets are in their holes.
Dont worry about pulling or pushing too hard, you really can't break anything.

put the air box back in the reverse order above.

Oh, That's INSANE!

I'm just taking the car back to the dealer and get a refund, maybe I'll buy a Corolla - I can't do all THAT!!

jasonrxeight

k a small question. I found my two bottom rubber mounts are missing. the dealer lost them when changing the filter due to an over fill.
where are they gonna end up?
how hard to get to them?

BG-8

if they haven't fallen out on the road somewhere, you could probably remove the undertray and see if you find them there.



EDIT: I could send you two of my grommets if you want, I have two air boxes...
