its there to reduce air turbulence when flow through the maf.

ive read that if you take it out, you may get problems if the maf gives a wrong reading.

Curiosity: That funnel/splitter is much longer on the Facelift than pre-facelift.

Nothing against you, but I have to wonder why ppl see something on a stock car, and seek reasons to remove it, as if there would be some hidden performance increase in doing so.

It's just something I've noticed on this site (that drives me mad). I'm glad people can't easily open up their fuel tanks/sumps to then find a reason to remove those useless baffles in there. :rolleyes:

There was a recall to replace the funnel in the older corolla sportivos...

And about removing stuff. I dont do it but i see it as the poor mans research and development... Trial and error :D

To reduce turbulance to the MAF sensor.

The car will become erratic to drive, and when it really confuses the MAFS the engine can flood.

Ahem... Removing the snorkel has an obvious and measurable performance benefit! The funnel inside the airbox however is another story.

To me that's like wondering why you put a washer on a bolt. I thought the distinction between performance/necessity was obvious...

Chicken: Would Toyota replace my shorter funnel with a longer one as part of a recall still?

you should have a recall sticker near the drivers door if it was done.

the recall replaced the old funnel (from DRF122R) with this (from bonbon)

I have the shorter one with the fin in the middle. This is the good one eh?

Gav.

Yes. The dealers didn't always put the recall sticker in when it was done.

yep, the sportivo recall was to improve performance to meet the sports car category. there's an old thread about it somewhere for more details

So the OP's sister's boyfriend should get himself a short white funnel rather than removing it entirely. :)

I'm not surprised if they didn't.

I'm Back after being sick :(

I have the original White funnel in mine... and took it out sometime ago and was running the car fine for a while without it... then doing some research on here about it, i discovered it was best to leave it in there, so i put it back in :P

      overheated engine

      I drive a 2010 series 200 sahara V8 automatic. I recently towed a small caravan on a not that hotter day. The temperature gauge went to about half then dropped back to normal. The motor then went into limp mode and eventually stopped. On lifting the bonnet i noticed the top radiator tank had split all the way across. I have only two months ago had the complete cooling system checked with no defects. I called the RAA in South Aust and they tried to start it but just turned over but did not fire up. It was still pretty hot. I have been told the motor would be ruined by overheating. The car has been sitting at the repairers for 5 days now and as far as i know it has not been attempted to start. Before putting a new motor in it would it be worth putting a new radiator in it and see if it will fire up? Open to any suggestions at this stage.

      1996 Trueno XZ - Is it worth modding?

      Depends on how common/rare they are in your part of the world. The XZ trim was the second-lowest so didn't come with most of the fun bits that the full-fruit BZG/V/R models did, so it's not anywhere near as desirable stock but sometimes you have to make do with what you can find, plus you shouldn't feel as guilty modding the heck out of it since most of it isn't special.

      VSC, Traction Control, Check Engine lights all on

      I attended Toyota Preston for Aurion ATX 2013 major service today. Cost $~$1300. On the way home I stopped to pick up dinner. Two fault lights: engine and VSC lights came on when I restarted the car. Car drove home just fine. I can only return the car tomorrow for them to sort out. Annoyed. Let’s see if they’re still on in the morning.

      Hi everyone, new member to the group and owner driver of a nifty little Toyota Sprinter Trueno XZ, now this was my cousins car, I bought it off him and after various drives, I have come to the decision that this needs alot of love. Now I am wondering if its worth putting my time and money into doing this certain make n model up or should I just buy a different car to do up? I am not very car-inclined so I really don't know a lot. Any opinions would be very helpful Thankful!

      Android auto

      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
