I ran into an interesting problem the other day. I pulled out of a parking lot and got on it about 3/4 throttle, boost gauge showed 18ish then dropped to 0 and the check engine light appeared. The next morning I dropped it off at the dealer and they called me awhile later to tell me the mass airflow wasn't responding and they have a new one on the way. The next day I got a call saying my car was done and my CAI was the problem. Apparently the rubber portion of the CAI was collapsing under heavy boost choking out the motor. I emailed the problem to Injen tech support and they told me this is a known problem which they have fixed and would send the replacement rubber tube right away.

So if you have the Injen CAI SP1837 (http://www.injen.com/Galleries/ProductPress/SP1837P.jpg)

email/call and get the replacement rubber hose. Once I put the new one on all is well. They double the hose thickness all the way but the ends attaching to the metal tube and the filter.

Just an FYI

 

As someone who owns an '05 Ralliart, hasn't posted here in ages, and just lurks, I laugh at this. You have a CAI and don't have a tune on your car, gee I wonder what the problem is...

 

You obviously havnt been around for the long tread about how our car comes from the factory extremely rich, and the intake bypasses some air past the MAF to trick the car into running leaner. The intake does not require a tune if you leave your car mostly stock. Not my cup o' tea but it works for some people.

 

This post makes no sense. He states that INJEN admitted a fault with the hose that the dealer found.................. How is this in any way related to him not having a tune?????????

 

^right. I think what the OP was meant to get across was, well exactly what he wrote. That there is a defect on that part and if you have one, take care of it. I think he was trying to do everyone that has the part a favor. If he doesnt run a tune with that intake who cares? Honestly I think SkyGTR posted in the wrong section, but then again the new Ralliarts have so much in common with the old ones...NOT

 

Thank you guys for understanding what my post was about. I'm not sure if many people have the Injen CAI or even have/had the same problem I did.

Oh and SkyGTR, No I don't need a tune on my car, having an AFR in the very low 11's under full boost is still rich. I believe the threads involving your car start about 6 more catagories down.

 

lol sweet thank you for this, ill have to call them or maybe they started putting these within all there new cai as i bought mine about 2 weeks ago maybe

 

ya kno just to add a lil more to my above post, i was kinda iffy at first when i saw the rubber hose, i let a friend revv the engine a bit as i squeezed it and it seemed fine, but i guess when its under driving conditions and your cars boosting and pulling and what not it may get to that point. I hope i dont run into these issues, but i will call them and ask. Thanks again

 

normally, i would agree with you, but sunshdw is one of the few with a wideband o2 installed that actually monitored his afr's to determine if the injen was causing an overly-lean condition and thusly decided it didnt require a tune for safety's sake. reading other threads on this matter would have shown you that, and that's why he specifically mentions that he doesn't have a tune in his sig because of the testing he has done to show that on his setup it is safe without one

like everyone else was saying tho, the purpose of the thread was to advise others of the tubing upgrade to keep everyone else, tune or not, from having this issue

 

About the best comparison I can give is the new hose is a bit harder to squeeze than the rubber hose off the turbo. The first one took maybe 1/4 the stregth.....

Thank you, very well put. I've read many debate threads about that subject which is why I did what I did.

 

anyone got a pic of what this looks like installed?

 

i think evil03 had pics from his install a while ago. pull up his profile and you should be able to look at his statistics for threads he started, it's there somewhere...
