Hi guys, i saw a while ago on here someone had written up a how-to for switching the vacuum hoses around on the stock aurion intake. Iv been searching but can't seem to find the thread. Can someone please post the link for the thread in here for me?

Thanks

Tom

AUR30N

well i just bought a k & n drop in filter so i figure might aswell do that too. Give it a bit of a better note

ooh let us know how it goes, if you can, it would be great to post up pics of the install for us to follow

If you've changed your own air filter before, that is about as exciting as photos of this process is going to get.

Extra induction noise really. Just for looks more than anything.

haha ok never mind, had to take a 2nd look n figured it out now. if people want it i can post up picks of how to do it but djkor pic is basically it. Just have a look where the round cap sorta thing is before the airbow and see where the vacuum line goes. Then just basically switch the lines around to look like that.

will changing the hoses make any difference in induction noise if your running the stock filter?

It is barely even noticeable. To get it to the noticeable stage, you need to remove the lower resonator and the carbon filter in the top of the air box. Re-doing the upper resonator will make in the intake even louder, and re-doing the front snorkel makes it approach SRI territory.

Sorry dont know much about this stuff at all, but what would be the advantage of adding a pod filter? And how difficult would this process be for an Aurion?

I wouldn't mind lowering the note without having to change the whole exhaust

There isn't much benefit to adding a pod filter either a SRI or CAI to the Aurion. You do get a mad induction sound. The installation process of it all is pretty straight forward.

We are finding that with the Aurion, whatever gains you can get from such mods seem to disappear after a bit of driving. We think this has to do with the AI of the ECU. Rowan found that after a while of using a SRI, changing back to his stock intake actually felt a little better.

While on topic, Rowan and I can pull similar times down the 1/4 mile when he has his SRI an I have my stock intake, minus it's restrictions.

That's why you usually hear the guys over at Toyota Nation with their Camry's saying to just get a K&N drop in filter and call it a day.

Iv changed around the hoses and removed that carbon filter out of the intake box, how do you block off/ remove the resinators? Do you actually take themoff and cover the holes or just block off the holes with the resinators still in place?

You can simply remove the lower resonator and leave the hole open. Useful for keeping the airbox clean. As for the upper resonator, you need to be a bit more creative there. There was all this discussion over at:

Air intake mods

Should have a look at that first.

I did this mod some time back, but I never really noticed any difference...

Maybe I should have driven my car with the music off before hand. <_<

p.s. I ripped out the carbon filter today and i forgot to plug MAF the sensor back in before turning the car on...Turned it off then plugged it in. I didnt see any engine lights or anything but when I scanned for error codes with my Scangauge it gave me the following engine error codes.. P0102 and P0000, both meaning MAF errors. I reset the codes using the Scangauge.

I did that once before as well. I got the check engine light and 'Check VSC' come up on the display, even after stopping the car and plugging it back in. I just pulled the ECU fuse for a few minutes then put it back. Check engine light gone, and after driving it for a bit, I would say the error code as well.

      Took the dust cover off, heart skipped a beat

      Not sure how many of the old guard are still around… fluids drained, fuel tank cleaned and lines purged, might be time to throw it into gear again.

      Need Advice please

      Suggest that you look at an online catalogue for struts/shock absorbers specifically for the Year and Model specification for your Camry. Easiest way to clean fuel injectors is to use a fuel additive together with decent quality fuel.

      What can cause 2x bolts Missing on break calipers?

      For starters, you are referring to the BRAKE calipers. Missing bolts is highly probable that whoever last worked on the braking system did not properly tighten the bolts to the correct torque specification. Presumably, the brake pads were replaced approximately 6 months ago.

      What can cause 2x bolts Missing on break calipers?

      Hi All, I have sent my car to a local mechanism shop as I heard a big scary clunk noise from the front left wheel part recently. And a huge surprise came back to me is, they told me that my break calipers has two bolts missing. I don’t think it is a common problem caused by daily routine driving. So really need to find out what was happened to that 2 bolts?! How lucky I was for driving nearly half a year without a tight break!! I even have kids on my car… can’t think more now. It’s terrifying 😱

      Engine Immobiliser

      Hi Chris, I would suggest getting a code scan as well mate as it could be something locking out the security starting process, and it may make tracking it down faster for you maybe worth the fee for a mobile mechanic who can do that for you as I doubt it will be a fuse or relay causing it sounds,like something in the security side of the process. I am sure if any others have ideas they will post it, these are just guesses on my part so I hope you get it sorted fast mate KAA

      Fuse boxes info

      I have a Toyota tarago 2002 acr30. I'm trying to find out where I can get the contents list of all the items in the fuse boxes. I think it has 4. I only have one cover in the engine bay fuse box. The other three have no information anywhere. Need to know what the items ( fuses, relays ) are for ?? If anyone can help would be a nights sleep for me..

      Rav4 Nightmare After Dodgy Mechanic

      Hey everyone, hope you're doing well! Unlike me and my Toyota, which is currently in a bit of a mess, haha. I'm reaching out for some help, feeling pretty desperate, to be honest. My 2013 Rav4 2AD-FTV Turbo Diesel is on the verge of being a total loss thanks to a dodgy mechanic who really messed things up. My car's was pristine, but then it blew the head gasket. I acted quickly, called up a mechanic recommended by a friend, and he towed my car away promising to assess the damage. He later reported that the engine was still in great shape but needed the head gasket reshaped to fix the issue. Weeks turned into months, and despite numerous promises and missed deadlines, my car remained in the shop. The mechanic stopped answering my calls or messages, and when I finally tracked down my car, it was sitting outside another workshop, unable to start. Cut to now, after seeking help from a reputable diesel specialist, they've replaced seals, checked compression, swapped injectors, and pretty much everything possible. But my car still struggles to idle, and they suspect the previous mechanic may have messed up something electronic or electrical. I'm at my wit's end. No auto electrician seems willing to touch it, fearing it's a money pit with no guarantee of success. It's incredibly frustrating, especially considering I may lose the car. Any advice or suggestions would be greatly appreciated. Thanks in advance!

      Door seals - causing internal leak

      Hi experts need some help. I have a 2004 Sahara 100series. With all this rain we are having my car has started leaking. It was my father in laws car. It’s leaking water down the pillar trim where the handle is inside front seats onto the dash, down the side of airbag and glovebox and dripping from corner foot area where dash ends and onto the floor. I can see the seal on the roof above the door has a gap in it. Could this be it? 1Q. Who would I get to look at this? 2Q. Anyone had this issue before? 3Q. Where do I begin. Thanks in advance, Sarah IMG_3589.mov
