Howdy all, first post for me as I've moved over here from the WRX community.

I am after some advice on what is doing with this mod.

I recently purchased a stock 02 corolla. I put a cold air intake (short ram) onto the car and started it up. It sounded ok for a little drive but when I got up this morning and started the car the intake sounded like a cyclone. The pod sounded like it was sucking air in but it was that loud I had to take it off it. This was just on idle. The car also idled a little rough. :blink:

The intake is model specific (purchased from SportivOoo_03)and I tried two different pods with the same result.

Any info would be great. :help::help::help:

PROCEDURE I DID:

Remove stock air box.

silicon elbow onto throttle body then attach pipe with air flow meter attached to top of pipe in the allowed spot. Attach pod and then the two, I think they are, vaccum hoses back into the part that comes off the factory box.

cheers

ehmm2x....i dunno whether u have the same prob as me or not but...i think almost the same.i would like to clarify again, r u using the stock pipping?im using K&N pod filter attached to stock pipping, it makes cyclone noise as well....and my mechanic says that the idle level is too low.... he told me to ask the toyota mechanic to increase the idle level when i service it but the toyota dude told me that they cant (dunno why). its only making cyclone noise when the engine is cold.but once its warmed up, it'll turn back to normal.im used to the noise now...since it doesnt troubled me so i just leave it as it is.well not sure if this is helpful but just letting u knw, i have the same prob. dunno exactly why...

Thanks for that. Not using the factory piping just the factory part that the two hoses go onto. the pipe I use is metal/aluminum.

Mine does that too, however I have a CAI. It does it for a bit and then, I always assumed when the engine got warm, goes quiet. Now this thread has gotten me thinking, what exactly is happening in this process?

Hey sal 02 rolla - funny that ur moving from the wrx community -- i want in!!

try resetting the ECu - take off the battery terminal connecter and pump the brakes a few times to drain the resdiual charge. Start her up and let her idle for about 5-10mins .

'Cyclonic' is pretty loud lol - rock up to one of the meets and get one of the resident experts to have a squiz.

I'm guessing it's just hte ECU adjusting to a new mod, finding the in's and out's?

Thats just the engine when its cold, it will be fine once its warmed up.

Additionally you need an ECU reset, just do a search for it and your car will be running fine.

ECU resetting euy?heard that one before but never been able to do it.is it safe using that way?so i'll just have to disconnect the battery, press the brake for few times and connect it and start it then let it idle...and the wat?

The sucking noise is normal you hav nothing to be worried about. Once its warmed up its sweet as. My car since installing the CAI on start up coughes and chokes sometimes but after letting it warm up for 1-2 min it good. The sucking is even louder on a very cold day or early morning.

rough idling can also be affected by a dirty MAF sensor, so get some electrical part cleaner spray and give it a good clean as well as resetting the ECU.

Cold start on CAI/SR are all very VERY loud.

cheers.

:D :clap: That's gold. It was a sad sad day. if only you could live in your car like the mother in law keeps saying. lol

Will try the reset, thanks for that.

ROLLA, your sound is exactly the same as mine. Coudn't believe how loud it is. I was worried it was waking the neighbours........... three streets away.

The heating up would explain why it was quiter when I first fitted it, as I fitted it after a drive so the engine was already warm.

Don't suppose their is a way to make it quiter on start up??

Thanks everyone for the replies, really helps when you realise it's not just my car. :toast:

Cheers.

Embrace the cyclonic sound of your intake on cold idle! It's one of the joys of Corolla ownership - waking up neighbours with your "outdoor vacuum" :help::help: and having police do a dB test on your stock exhaust after they hear your intake :help::help::help:

Great fun :D

This is normal with most toyotas, even my ae82 hatch witha bigport 4age does it until it warms up, the pod makes a massive sucking sounds on start up, nothing to worry about.

Just make sure you don't drop the MAF sensor or you will be screwed!!! They do not like to be handled roughly!!!

      OK. Does any of Toyota's advertising material mention Android Auto? If so then kick up a stink, with Toyota management, about misrepresentation and false advertising, reminding them of the hefty fines. Herb

      1999 Camry Driver's door locking hatch issue

      It's possible that it could be something fouling or dirt build up, dry, or a broken mechanism, so have a look and give the mechanism some lubrication, most likely though, it'll be the actuator. I found one for a good price on Ebay, $25 delivered: Front Door Lock Actuator Right Side For Toyota Camry 1997-2001 | eBay

      Query about the correct rotors for 2006 ACV40 Camry.

      Hi, I'm looking at a set of front rotors for an ACV40 2006, 2.4L Camry. I got a good price on some RDA's at Sparesbox. However both RDA8112 and RDA7686 show as for my car and I'm wondering what the difference is and if there were changes to the rotors during the model production. So does anyone know which rotor is the correct one? Many thanks in advance.

      It's a simple solution though? Already laying down 60k for a RAV4, so what's another 1k on a phone to make everything work seamlessly? 👍

      Your solution is akin to suggesting that switching to a different car manufacturer would resolve the issue. However, not everyone shares the same enthusiasm for using an iPhone as you do.

      Turboed Corolla Overbuilt?

      that engine will be fine, the rods are the main thing to be concerned about. The 2860 is a decent turbo for the 1zz but in this day and age I'd go for a G25-550. The injectors might be on the small side, we run DW1000's. You need a full length injector, the shorter injectors with adaptors like ID1050x dont fit the 1zz head. You don't need an aftermarket intake manifold, if you do go down that path, avoid the CNC innovations unit, it's garbage. Do the boost control with a MAC valve and control it with the aftermarket ECU of your choice, I use Link stuff on most of my builds with the G4x Storm as the minimum. I also wire a fuel pressure sensor and oil pressure sensor to the ECU in my installs. Use a decent intercooler, the better cores (ARE, PWR, Garrett, Vibrant, Plazmaman, Hypertune) work a lot better than the chinese stuff like Aeroflow. a 450x250-300 fits fairly well with custom end tanks to route the cooler pipes through next to the radiator Don't forget about the clutch and gearbox. These days I like the Uniclutch twinplate, Above 300whp you'll want to think about upgrading the 3rd and 4th gears in the box also with the SSC (Hollinger) gear set and install an LSD of your choice. If you're going to give it a hard time, you'll also want an oil cooler. I like the HKS thermostat type sandwich plates and setrab or mocal oil coolers with -10 speedflow fittings/lines (Chinese AN fittings neck down to a lot smaller internal diameter in their bends, not great for flow) You'll also want to think about brakes, Celica or Sportivo front calipers will bolt on with sportivo discs as a starting point. To have somewhere like Tunehouse do the work you'll want to budget somewhere between 20-40K

      Camry Touring 2010 Fuel consumption 15.2L/100km. Normal?

      I did the mathematics myself regarding costs vs benefits for fuel injector cleaner. I have changed from 91ULP to 95PULP and 98PULP. Price difference can be about 13 -20 cents. Compared to 91ULP, Premium quality fuel should have a better quality additive package designed to have superior engine cleaning capabilities so the engine can perform at their best.
