Default Cold Air Intake on 2008 2.5i

Hi, I was looking at putting a cold air intake on to my 2008 imperza (2.5i) I was looking at a K&N 69-8004TTK Would work for the 2.5i? To me it didn't seem like it due to the location of the air box. Are there any intakes around for the 2.5i?

Thanks for your help
Alex

Do you have exhaust? If not, I would do that first if I were you. Then intake, then tune.

Personally, I do not believe that these intake systems are worth the money. $160 for a cone and some piping? I have owned 3 1st generation legacys and I just take the stock airbox off and fit a cone to the MAF sensor. Now I know that your 2.5i intake system is a little different, but I would just cut the stock intake piping where it enters into the airbox and fit a cone filter to it. You can find a cone to fit the pipe at any autoparts store, for like $30. I'm sure there is no big difference if you do this compared to buying a system. Plus you do not have to re-route any hoses, it is all ready and set to go with the stock piping. Definitely you will feel much more throttle response, and the car will sound much throatier. I would just try this first before you go spending $160+ on something you can do yourself for much much cheaper.

do NOT get an intake. They are useless, they will rob you of mid level torque, they are expensive, and they will probably give you CEL's. Totally not worth the money for the small small amount of gain and the complications that come with it.

If you are still interested however, go over to the Normally Aspirated Forum and check the sticky at the top : http://forums.nasioc.com/forums/show....php?t=1471819 That's the only intake that will not rob of you torque and will not give you a CEL.

Really? i hav no clue y this would rob you of torque or cause cel which i have no clue what that is but i no the o2 sensor or sumthing is sometimes messed up when you do this but my main question is would this be acceptable for rally or would that suck in more dirt and possible water on a water crossing?

the main problem is your maf. you maf works with majorly on air/fuel. you will be screwing that ratio up. now if you plan on making it a straight rally car then you might not care for short term if it runs rich as hell but long term can cause problem. deff dont do it if its a daily driver also. theres a better alternative thats safe and gives you some noticable gain. just as much as a true sri/cai almost. also check this out to.

Even if a CAI did not do any harm, why would you even need it? The stock intake does a great job at being an intake, and doesn't look like a careless bolton. Setting the CAI or money on fire would provide better bang for buck since it would offer you temporary heat to keep you warm.

The intake you have is pretty awestacular as it is. Changing it would cost you money with no gain. Use that money on some suspension upgrades.

i put a cone on my 07 2.5i it tripped cel's but i found a way to do my own intake, you keep the airbox put a k&n filter in it leave the maf and post maf to the box put your own tubing, then take out the intake silencer that is in your fender and put a wrx air duct works just like a cone doesn't trip cel, gives that throaty sound, i have much better mpg and throttle response, and it trips cel because were na only way around it is to tune the maf or get a bigger one but my way its 50 for the filter 3 bucks for the pvc pipe and like 10 bucks for the fittings and i painted my pvc pipe to match the theme of my car.. these pics are before the wrx duct



i hope this helps, oh btw when i switched from the regular duct to the wrx duct kept the airbox ice cold ans same with the pipe after doing 60 miles at 80 mph
