can someone tell me if this is normal??!
situation: check engine light comes on after 5 days of driving with Injen CAI
I take apart the front tubing today to see what's up while disconnecting the battery, this is what i see:

is this normal? If it is, i didn't know the stock injen filter lets in that much crap

Does any of that come off with a wipe or is it stuck to the tube? I thought the filter wasnt that great as it was, so I put in a K&N style filter with the apexi design.

I used the injen filter that came with the cai... that's why I was asking if this is normal cause the pipe now looks pretty messed up
i'm not looking into k&n or apexi.. but i'm not sure whether to put the stock intake back in and then switch it off again or just run the injen with the crappy filter for now and wash it again later.

I used a 3" filter that Alex at Southwestautoworks.com has in his store. You can call him and get one. I'll take some pics later on tonight and post em. I like the filter a lot and when its dirty I'm just gonna buy another one.
#9
Can you send a picture and maybe post a link to what type of K&N filter you bought? Like what size do you need to use -> 3" opening? I don't plan on using the Injen filter that comes with the intake, I want to go with a brand-name filter, not some generic junk. Thanks!

i'm a bit worried right now cause i'm thinking that whatever messed up the tubing inside also set off the check engine light
I reset the ecu by disconnecting the battery for a couple of hours today and I totally took apart and cleaned the tubing on the cai and put it back
I just drove 5 miles on it at different speeds and revving it over the rpm range... things are fine.. for NOW. I can't justify paying 70 bucks for the apexi filter, but if the piping is all covered in dirt again in 5 days... i'll have to go k&n or apexi

a little off topic, but i love the way the valence grill looks with your color max and the headlight and turn signal bulbs.. very sharp.. but the license plate has to go.. it's worth the hassle from the 5.0 because it makes the car look 100 times more aggressive

Can someone with a setup similar to Larrio's check their install and see if the same thing is happening?
Larrio, try rubbing those line marks with something like goo gone (that will break-up tar or goo) and see if it removes those lines. Check the goo gone on a small area first to make sure it won't strip the finish inside the injen.

The scratches were most likely there from the get go. Dirt tends to get into cracks, scratches and stick there. That leads me to draw the conclusion that your air filter sucks. It's letting in quite a bit of dirt which is lodging itself in the cracks and scratches along the pipe walls.
Your CEL may have been set by your MAF sensor. To bad you 5th gen guys can't get the codes from the ECU without scan tools.
Personally I wouldn't be so happy with that intake after seeing that.

the hole that is in one of the pictures is for the oxygen sensor to be put into.
njmax... and your right, i'm not too happy with the filter. I mean it's it can't filter everything.. but I don't know about that much dirt going through.
I reset the ecu by disconnecting the battery, cleaned the pipe, reinstalled everything and took it for a spin.. about 10 miles. Everything is fine so far and the car is friggin' fast.. but we'll see after I take apart the pipe in a couple of days.
The weird thing is that the front pipe piece is full of dust, but the MAF sensor area was clean when I wiped it with a towel. All other areas made the towel black after wiping it

I emailed Injen yesterday and they replied today in the afternoon regarding the piping issue:
"What you are referring to is the polishing dust for the buffer machines. This will not harm your engine. You can push a rag through the intake and it will come off easily. Compressed air will work as well."

Larrio, what you're referring to as an oxygen sensor is really the intake air temp sensor. When you reinstall it you might want to put some silicone RTV around the rubber grommet, and under the sensor itself, to ensure an air-tight seal. That could be one source of the dirt.
As for the "polishing dust", if it really does polish metal then it's abrasive and should've been cleaned out before they sent it to you. Also, I'm guessing the long scrtatches you see inside the tubing are from the mandrel bending process and are normal.
