I have a Injen short ram and haven't had any problems yet either.

 

don't know if this has to do with the maf sensor ,but they have an TSB out concerning rough idle in the xB's.

I HAVE AN ROUGH IDLE IN MY Xb SOMTIMES (HAVE NOT HAD TIME TO TAKE TO DEALER YET) .DO NOT HAVE CAI YET.

There could have been a problem with your MAF all along ,just did not show up right away. glad you got it fixed at scions cost.

good luck with your box in the future.

Dude,
You were paying $80+ per horsepower gained, and it took all this drama to come to the conclusion it wasn't a good deal!? :D

At the same price rate per HP gained, I'll sell you my extra 50 HP NOS kit- it should be worth about $4000 to you. ($80x50HP=4000) and then you will have so much power that.......................................you will still get spanked by a 1983 Escort.

You should heard the dealers speil to me about "you gotta get the cold air intake" because it was going to add so much power. Give me a freakin break. Yeah, I could drop a grand on the intake, exhaust, some goofball sparkplugs, and a big chrome sticker up the side to add what- 6 HP? WOW! I could probably break through the 20 second barrier in the Quarter.

 

I never had any problems with my injen intake. Maybe you didn't tighten the MAF all the way.

 

LOL! Gotta have that mad tight intake as the kids say. Yo dawg my MAF is junked up but I gotz to have that bling bling and that mad rush of air that's music to my ears. (107 hp is mad power yo, you can beat 2k3 mustang cobras with an intake and 17 inch rims)

 

SO did all of these people have an Injen CAI.... Sounds like MAF problem all together not Injen problem.. Yes the said they found no problem but fixed it anyways and warned about aftermarket products.. sounds like BS to me b/c if wasnt a defect and they thought it was aftermarket part that caused problem they would have charged you for the MAF sensor. just my opinion...

 

Just a bit of speculation ...

1. Did the dealership say exactly what was wrong with the MAF sensor? I wonder if the problem could be mechanical damage to the delicate sensor wires, not fouling. That might explain why cleaning the hot wire didn't fix things. It wouldn't take too much extra vibration to damage those wires ...

2. Where exactly is the filter located on the CAI? The filter for the Injen short ram sits in what I'd guess is one of the cooler parts of the engine compartment, with no nearby sources of heat other than the left headlight. If the CAI inlet sits near other engine/transmission components, I wonder if heat soak might be burning off the oil in the filter and causing premature fouling.

 

Hi Fuglyxb. Sorry to here about your problem. I went though the same thing. What type of CAI is yours? Mine is the RD2105P The one with the weird bends. I cooked 2 sensors. The first one with out the $8.00 inline oil filter defuser from injen. Which was not in the box or in the instructions when i got it. Then i had to buy the thing and guess what it cooked the second sensor. Fuglyxb my email is nick_gerace@yahoo.com if u want to talk more. later......

 

sweeet..

K&N, YEAH-K&N!

Breasts - W-Wings.

 

gayest commercial ever. also, i was born in Elmira, NY. Only thing I miss about the place is Lights Bakery.

 

I was being sarcastic... don't know why the service department was backed up and taking diagnostic appointments based on a 7-day wait, especially for all these reliable Scions/Toyotas <---- (more sarcasm)

as predicted: Of course... that was it!!!! NOT... maybe I didn't plug the sensor back in either

As for zombietime and sweetdaddydelicious (both learned scholars judging by their catchy screen names) this thread was never about debating the dollar/whp ratio of a CAI, but thanks for your .0000000002 worth.

Sithscripter: No detailed assessment as to what damage had occurred to the MAF. Other than spraying the contact cleaner, no direct contact was ever made with the MAF wires. The Toyota MAFs seem extra sensitive. I made an intake for my Hyundai (ironically from an Injen Civic intake) and it hasn't killed that MAF (yet?) even with a K&N oiled filter attached to it right out of the box. Hell, the filter has worked itself loose a couple of times so that I wasn't running ANY filter and that didn't kill the Hyundai MAF...

The Injen CAI for the xB locates the filter just ahead of the driver's side front wheel... no significant heat sources I can think of there. Thanks for your intelligent suggestions, though - refreshing change from some of the usual knuckledragger comments - apparently some of that Three Mile Island fallout affected the residents of Elmira NY especially hard...

 

FU xB,

Naw, it is the acid rain fallout from the black smoke you guys call air over there.
I was simply saying, in a light humored way (something you should try on, maybe), that the K&N intake is starting to sound like a safer bet. Actually taking your side in spite of your offensive attitude towards others. I understand the defensiveness but, there's no need to be mean. Anyway, I had a bad MAF code on my contour.. replaced it and $100 later no change.. turns out it was the 02 sensor. Which I couldn't reach without taking the FE off the dang car. So, I sold it and got an xB. I like the xB 'cause the seats sit high. 'keeps my knuckles from getting stuck in the door sill when I close the door.


That one and the freaking bridgstone comercials during the F1 races "and the wheels go round and the wheels go round"... "and the channel gets changed".. aurgh, I can't stand them.
Congrats for being born in Elmira. I hope your knuckles have healed well. Lights is good. We have hockey now, and a good mexican rest. too! I really like it here, but have been lucky to stay employed, though I have had to drive 45-60 minutes to work for the last 5 years

It is just as likely that the aluminum dust caused the MAF to foul as the oil from the filter may have. Aluminum dust, being a conductive metal, has the potential to short out or generally mess up any electrical sensor.

I installed a K&N CAI in my xB, and the instructions specifically stated that before performing the install, the tube should be thoroughly washed and dried to remove any contaminants. (I'm not familiar with the Injen instructions. Do they say anything about this?)

As for oil contamination... I noticed the K&N CAI tube has a small deflector plate a few inches before the MAF. I assume the purpose of this plate is to create turbulence in the air flow to encourage any oil droplets to hit the deflector plate or the wall of the tube instead of the MAF. (Just out of curiosity, do the Injen or AEM CAI's have this feature?)

For what it's worth, I came across this page on the K&N website which discusses their opinion regarding their products and MAF sensors.

Thanks Clipper for all of that info... Far more insightful than most of the drivel posted in response to my original post.

No tube cleaning instructions are supplied from Injen, nor is there any deflector plate etc. in the Injen CAI.

Should give potential CAI buyers reason to think about a K & N over the other brands.

I like their statement you linked to - shows they are aware of the problem and acknowledge it, which is more than AEM/Injen do...

If I had it all to do over again, I'd buy a K&N!

 

Sorry for joining this thread so late in the process. I installed an Injen SRI about 600 miles ago. During the install I noticed a filter that appeared to be for the breather hose. The instructions did not cover the installation of this part.

Due to the position of the breather hose upstream from the MAF sensor, I decided to install the filter in the hose. It did not appear to be directionally sensitive, so I just installed it as I thought it should go. The following link is a picture of this filter.

Just wondering if others had this extra part, and if so, who installed.

Car is running fine, by the way.

 

Injen started puttin that piece in the kit a few months ago. Mine didn't come with the kit, but I ordered it from Injen for $8. Injen suggests replacing it every 10K or 12K miles. BTW, I'd put clamps on the hose ends around this filter just to be safe.

Also, when using an electrical cleaning product for the MAF, make sure that the back of the can does not say "Not for sensitive electronics". For example the CRC Auto Electronic Cleaner should NOT be used (although it would seem so). Get the CRC QD Electronic Cleaner. It is specifically meant to clean very delicate electronics. The one for Auto Electronics specifically says not to use for sensitive electronic contacts. Also "swabbing" the sensor may not be a great idea. Get the kind of cleaner that spays on from an aerosol can and self drys. If you think that there is some aluminum pieces contaminating it, then get a can of "Endust" or other canned air duster. That's how I cleaned my MAF.

 

as in the qoute from my post i bought the cai made by injen. it blew my maf the dealer said my air flow meter was defective aka the intake cooked it. the stock box i put back on was missing one clamp so im surprised they replaced it . my dealer is the best. I am debating on getting the defuser i might just sell it. i have a reactive dry filter on it now as well as the original k&n filter. when i took the filter off after the umpteenth time trying everybodis techniques. i noticed metal shavings like dust almost but a little bigger . i thought it was just mine but i guess someone else had that issue as well. where the maf goes the soldering of that mounting block looks like it wa poorly connected. my opinion only. i have installed many intakes on other vehicles and have never looked at the inside of the tube to inspect the soldering. Then again i never cooked a maf before. anyone wanna buy a injen intake for cheap?

 

okay, i read the entire thread, and unfortunately for me, injen is the only company making a short ram intake. i don't want a cold air. so, with the added extras they are now putting in with the kit, should i get a k & n filter and use it instead of the injen one?
