Cold Air Intake - Question

[GrimlockGT]

I'm going to add a CAI to my Yaris and was wondering if anyone had any negative experiences after the install. In particular having a Check Engine Light error. CEL's drive me nuts!!
I'm probably going to go with the AFE one.

Thanks

Going with a known and proven brand you'll have no issues. Just make sure that all clamps are secure and the MAF is properly seated. Most CELs are caused by either incorrect piping size, or air leaks.

+1 on Weeyari , i have an AFE Dry intake , its been on now for 50,000KM
not 1 CEL or any other problems .:thumbsup:

Just handle the MAF like it's priceless. Don't drop it or bang it around at all. In fact, I recommend that the first thing you do is un-plug it, remove it and set it aside. Then let it be the last thing you re-install and hook up.

[GrimlockGT]

Thanks for the input. Good to hear that if installed carefully there won't be any issues. :burnrubber:

Gotta be careful, I just put a K&N Typhoon Intake on mine and after 250 miles running it with no problems I got a a DTC of P0101 "Mass or Volume Air flow circuit range/performance fault." I cleared it by disconnecting the battery and I'm waiting to see if it comes back. Going to contact K&N to see if they have reports of similar issues with this intake.

I've got an ebay special INSYS intake, works like a charm for a fraction of the price.

WeeYari,
Didn't Adrian hydroloc / destroy his engine after sucking water in through his CAI?
:iono: Or were his extraordinary circumstances we shouldn't be concerned about???

[WeeYari]

Extraordinary circumstances.

He modified his stock air box. Took the inlet tube which curls up and flipped it so it pointed down and added an extension to it so that the mouth of the inlet tube was way down low. He then encountered massive amounts of standing water driving through one of our biggest rainstorms ever, and vacuumed it up off the road. :(

Personally, I prefer, and am more comfortable with short ram style intakes. Not really keen on those that place the filter in the wheel well. Much easier to address filter maintenance too with short ram.

[cali yaris]

Note: The OP is getting an AFE, which is more of a short ram style, not a CAI.

It would be practically impossible to get hydrolock with the AFE. The filter is at the top of the engine bay, protected on all sides and sealed against the hood (or nearly so).

[WeeYari]

^ Yep.

Looks like you decided on the AFE, but I'll answer your post in saying that I used the TRD (really an AEM) CAI that mounts the filter below the right headlight, then vented my foglight cover to force in cold air, and I had fantastic results. According to my SGII, the intake temps dropped from around 100 F to 1-2 degrees F above ambient air temps.

I commuted in all weather for almost 2 years (Dallas actually has 4 seasons, winter is just short, but spring is really rainy) with no problems, and was very nervous about hydro lock until I checked the filter after driving home in a real gully washer and found it to be fine, with only a little dampness on the bottom side. That included 17 miles of 60mph driving behind other cars on the freeway, rain pouting down in sheets. I never worried again.

Seems like cels happen to most intakes seems like it hit or miss.

Wasn't your filter designed to handle wet situations anyways?

^ I have had three different cold air intakes on my car now since Ive owned it, different brands, filters, everything. I havent had any water issues here in Maine, and usually when it rains here, it RAINS.

I have had the ebay 1st gen AEM knockoff; Bomz cold air, the simota cold air, and now the AFE.

They have been great, never had one CEL

[06silveryaris]

I had a ebay chepo cai intake never any cels but I did have to many big puddle water over the hood scares so I sold it and got a drop box simota instead.

:thumbup:you might wanna check to see if any oil from the airfilter got onto the MAF sensor it might have triggerred the DTC:respekt:

lol people on here act like if your intake sucks a drop of water its gonna explode. The first 20 times it happens your car will stall and that's about it. To hydrolock you have to suck enough water to fill the cylinder to the point the piston can't complete its stroke due to water being incompressible. Basically you have to submerge most of the filter before you're bending rods. Splashing a few drops or even a moderate amount of water isn't going to do anything but spit some steam out your exhaust pipe and most likely stall you out.

As for CELs, no they aren't common. If you don't put it together right, guaranteed CEL. If you put it together right, guaranteed no CEL.

[ozmdd]

Never had a CEL on my CAI.

The TRD/AEM intake is made with an anti-hydrolock bypass coupler just in case you were to encounter too-deep water.

Oiled filters seem to be losing-out to dry-element filters, since the MAF is vulnerable to the oil when its over-applied. There are many great dry elements on the market these days that will not throw a CEL.

I personally took it off because rainy season here is very wet and where I do most of my commuting have water acumalation problems. I worked at a machine shop while in college and saw to many broken honda blocks and of course the bent guilty rod from hydrolock. I just figuered I play it safe and drive with no worries.

Why so many intakes? I bought the AEM and haven't looked back. Unless one can give me proven HP gains my AEM is here to stay.

Grimlock and I just installed ours tonight. His went first and took longer since we had to figure some stuff out that didn't seem right. Fitments and such. Everything worked out in the end though. Mine went pretty smoothly after figuring everything out with his first. Sounds great! Mine's definitely noticeably slightly peppier. Very happy I got this! And no CEL yet with the 25 minute drive home of both city and highway.

[nick.dollimount]

Picture of the intake installed. :thumbup: And still no CEL!

PS: Thanks to Grimlock for all the help!

[GrimlockGT]

Nick, thanks for your help as well.

I only got to drive mine to and from work today, but there isn't any issues so far. Definitely hear it when you get up in the RPM's! :w00t:

[nick.dollimount]

Yeah definitely! Also this morning, I had to pull out of Subway's lot quickly to get into traffic and you really hear it when you step on the gas from a stop :D
