ebay intake

Hi,
I just got an intake very similar to the pic... i have been doing a lot of research about it and have read that its not good to have any bends in the pipe before the maf.

if you look at the pic, the bottom of the pipe in the pic is where the air filter goes.. obviously as you can see there is a bend in the pipe before the maf. what i was thinking is to cut the bend out that way its a straight shot into the maf..

my question is should i cut the bend out or just leave it the way it is??



thanks.. btw this is for my gf wrx

I will tell you this with my HVAC experience, a 15 Degree bend limits the flow at that point to 90%.. So if your intake flows 100 cfm (numbers only for reference) you are only able to flow 90 cfm at that point.. However.. I would hope that the intake is designed with this in mind since I hope designers would know this.. You said this is an EBay intake, but I "assume" that this intake is a "Copy" of a brand name version.. I would suggest keeping it as is, if you find that the car doesn't perform as you would hope or expect you can always cut it then, however I would keep a silicone coupler handy in-case it messes with the MAS, which I would not expect.. Basically I am suggesting you leave the stock intake in place since it's flow capabilities are actually pretty good.. Just drop in a "Drop in Filter" like a K&N... But that is just my suggestion...

+1 for the k&n drop in,
but if you want an aftermarket intake go for it.. i have a perrin shortram intake with oil and cleaning supply for 50 bucks if you want it.
pm me if interested,

Gregory-
keep it in the dirt.

thanks, i just wanted to see if it might hurt the car.. so far all is well!! car doesnt seem to have any more power (exactly what i expected, power comes from dp & uppipe & tune) but does make crazy amounts of noise (turbo spool) i will see what happens once the out side air temp go up, like this summer. cause right now its like any where from 20-40 outside

Ohh yea, I forgot to mention that I also experienced a noticeable increase in "Whine" from my turbo when I installed the Blitz.. I personally loved hearing that turbo whoosh as it sucked in air and spooled up..

well today something new happened... my gf came to my friends house and then we left about 10 min later. the car was completely warm too. when she got in to start the car, it started then died. tried once more and died again. i tried it but reved it to make sure it wouldnt stall. once i was driving on the road i did a few pulls and everything was great. got home and car idled fine..

sooo... i dont know what that was all about, but decided that the stock intake is a better choice!!

my guess on why that happened was the bend in the pipe like i mentioned or it was the fact the diameter of the pipe wasnt the same as stock, therefore the maf was miss reading.

Will just the K&N make more noise or will I have to remove the intake silencer to make noise?
