I got a no name cai of ebay but im still using the filter it came with. since i installed it the car feels like it lost a few ponies. When i get to 5000rpms the intake screams load and it makes a loud crunching sound. Anybody ever experience anything like this. I have a 03 3.5 by the way.
i once installed my cai with the stock maf sensor box backward and it made a pretty nasty noise but i noticed it way before i started driven around in it... doubt thats your problem but never no
whats the difference bet. the ebay filter and the k&n? Please if you cant give any good insight to my issue dont respond like the idiot that posted last.
I'll I was saying is that you bought a cheap no name intake and your having problems with it, when there are tons of people on here that have berks, Injen etc. that have no complaints. I really dont know the differences between your cheap filter and the K&N, but there must be something that is causing the elements to crack and pop under load. What else could be making noises in an intake? Filter? tubing? You mention a power loss too, why are you flaming on my comment, it seems pretty valid doesnt it?

Sorry bro its just im use to people getting on my threads and posting nonsense when all i want is an answer. Thanks for your help though bro. I dont know what that crunching sound is though. I assumed it was the engine trying to take a big gulp of air and the suction was pulling on the inside of the filter producing the sound...but i dunno thats just an assumption. I think all intakes are the same cause its just metal tubing. I think the problem might be with that filter. Im going to get a K&N filter on sat. If that doesnt resolve it im putting my stock box back on. I refuse to spend 200 on an intake when its just a piece of metal or alluminum just like the ebay one.
My bet is that its the filter element collapsing or "crunching" when the engine is pulling the most amount of air. Picture a paper bag wrapped around a vacuum cleaner. Be careful ordering a K&N filter as most of the time they are "oiled" filters which seem to destroy MAF sensors in quick order. I would look at an AEM "dry" filter which does not require oil.
I went back to stock after trying the Berk, Ebay CAI, and VIAS plate removal, most gained some top end, but I definitely felt my mid-range torque drop significantly. The Berk was surprisingly bad, and I expected it from the VIAS removal. The CAI was the best all around but still worse than stock. I wholeheartly agree with your comment about the tubing being the same on any 3" intake. If I get time at work I am going to model the flow thru the pipe and see what the differences are.
Others have had success with all three of these, so try it for yourself. There have been many discussions about the nissan fly-by-wire throttle setup and the learning curve of the ECU. Every car can respond slightly different. I now rely on dyno numbers and 1/4 times to help weed out the ambiguity of opinions, including my own...
The crunching is definitely not normal - do you have a stainless mesh filter? Might be collapsing under load above 5k rpms.
make sure you have a good filter and solid piping. first mistake was buying an ebay POS. the berk v2 intake w/apexi filter is good IMO. especially if you live in rainy/snowy climates.
how does the saying go... you get what you pay for?
If you can find information on why one intake is better than the other, and can literally prove it to me, then maybe you could say this. I believe you are bouncing off of someone elses opinion vs going off of true fact.
The fact of the matter is that more than likely the filter is causing it to crunch, or something like that because that is what you are hearing. Get someone to sit in your car and hit the gas. Watch it and see what it does. If its that then replace the filter with a good one.
I ordered an ebay intake and i can tell you that there generally isnt any difference except maybe in the filter, and the piping wall thickness. If they all use 304 stainless, then 304 stainless is exactly what you are getting no matter who makes it. The difference will be in the filter if any at all.
Just because yours says injen doesnt mean you have the very best, it just means you spent your hard earned money on a brand name intake that does the same thing, and that is to deliver a certain amount of air to a car that is not tuned to use it (im sure), and expect to get large gains out of it. Unless you are going to tune your car to run with better air/fuel ratio, there is generally no benefit to the intake. Take your car to a dyno, and you may see minimal difference.
The tendency of an intake is to move the powerband, and possibility create power at the top end of the band. Generally intakes do not produce power, they just move the band. That is why the car is built with an enclosure around the filter vs being open and to the elements. Imagine sucking on a bag, you will pull the bag in and create a vacuum. This set amount of air that is being pulled in at a set rate that the manufacturer can count on. The car is then tuned to that amount of air. Now, imagine an open intake like a cai. It depends on whether or not you are moving as to exactly how much air is getting into that filter, and thru it, to combust in the chamber of the engine. It is never the same exact amount, i do not care who makes the intake.
Sorry, I just hate it when someone removes the intelligence from their brains and blurts out terrible non productive comments like that one.
"I ordered an ebay intake and i can tell you that there generally isnt any difference except maybe in the filter, and the piping wall thickness"
That was pretty much my point. He said he was hearing crunching noises most likely (not definitely) due to an inferior filter, ie you get what you pay for. I didn't bash him on his choice of intake, I just stated that you get what you pay for, sometime cheaper isn't better, and can I prove that with numbers, no, can I say that I have never heard crunching crappy noises coming from my Berk... yes.
