As thread, I want to start adding some tweaks to the scoob ( already has PPP fitted ) and feel the air filter should be first,but which one ?.
Looking for ideas here with regards to best filter/induction kit out there for reasonable money and more importantly what the general census is, induction kit or panel filter ?.

Any advice appreciated .

Cheer's.

imho i wouldnt use a induction kit as a tweek. subaru spent a lot of money developing the air box and filter method wghich to me is the best way to go. i changed the standard scoob air panel filter for a second hand K&N one off a guy on here (only £15-45 new) give it a clean and popped it on. car sounds and performs much more freely now, and the air box prevents the hot air from the rest of the car engine interfearing (as what would probably happen with a open induction kit)

Andy,

Guessed as much with the induction kit but am open to further opinion on it, there must be some benefits to having one ?.
Just thinking back to my cossie days and an induction kit was a must have.
So anyone else out there ?.
By the way it's a 03 Impreza blobeye to which the kit will be fitted.

Cheer's.

as per previous threads on this forum,only above about 350bhp does the use of an induction kit start to become necessary. even then a well routed cold air feed is a must.

that pretty much echos why i have stuck with the "air box" as it seperates the cool air for the maf turbo etc from the generated heat from giving her "some beeens"

im looking for a relaible 300bhp+ when a remap is done withoout many engine mods and a fellow off here told me to keep the standard air filter system and just upgrade the panel filter until serious bhp is required

Do panel filters kill the maf? iv heard some do and some dont.

pslewis

It's pissing about with induction kits which knackers the MAF and, said by some on here, to therefore mean an engine rebuild at a cost of £1000's!!!!

Do NOT **** about with it FFS

some form of induction kit will be needed if you decide on a fmic

Too much "bull" floating around concerning the limitations of the standard airbox. It may be concerned specific versions, but I know for a fact the standard airbox on a newage flows more than enough for well in excess of 420bhp.

I would only change to an induction kit, if a)I had reached the limit of the airbox and/or b)engine modifications required such a much - as already mentioned, say moving to a FMIC etc.

Shaun.

shaun is spot on on - i'm running 350bhp using a standard sti panel filter. Thery guys i know who use cones etc seem to get problem after problem

swifty.....!

i have wing induction on mine as this is seperate from the engine with an apexi air filter so when sat in traffic there is no heat soak also had no problems with maf etc. but as stated above the standard box can be good for 350+ think its more down to personal taste.

Also got 350bhp on a standard panel k&n filter from powerstation after remap and exhuast change. Supertouring has a induction kit, and tbh, I found it a bit grating, and not a little bit, dare I say, [cough]chav[/cough]

Nice to hear I can go upto 420bhp though before I need to get one!

My suggestion would be to spend the money on something else. If you have to do something, fit a new paper filter if the old one is contaminated. We tested a few panel filters and found aprroximately 0.0 bhp gain so we don't think you'll se any real improvement either

Cold air feed here. Don't put induction kit on if it's going to be just in the engine bay. The Cold Air feed will set you up for the inevitable upgrade cycle of cold air feed, bigger intercooler (Top or FMIC), Remaps, Bigger turbo, better brakes, better handling, blah, blah, stop now while you can, give your wallet a chance ........

Thats strange Mike, as we did back to back testing (and back again because we couldnt believe it made that much difference and then back again just to be sure), but between the standard filter and the high flow one we used it made 8bhp+ difference each time (without even touching on the positive gains everywhere else through the power and torque curve). As I said we tested this several times, same day, same rollers, same conditions. Not bad for a £40 replacement panel filter.

I have a hks shroom on mine. Only as it came with it and no standard box!

I like the look of it anyway and the sound that comes from it is great

am i safe in saying then if i put a k&n panel filter in my99 then the maf will live to fight another day? Its jsut shes going for a remap nxt year and i wanna start getting bits gradual.

filter
fuel pump
decat

then downpipe day of the remap

iTrader: (22)

well i got my full decat a few days before the k&n air filter, and even for a second hand one you could tell the difference. for starters theres a swoosh noise from the filter that wasnt audiable before and the turbo loves it and spoos quicker and louder too. all in all probably the most sensible mod il do to the scoob, besides the remap and bigger brakes lol

Just to clear up a few facts then, a K&N panel filter would be a safe and wise decision? Some people in the past have said using an 'oiled' one can cause problems?
I've on 04 WRX.

The pressure drop across the std paper filter is less than .01 Bar as were some of the other filters so there's nothing to be gained by fitting something less restrictive. Maybe something else is giving the extra power like a small change in flow past the sensor and a slightly leaner mixture although this wasn't borne out in our engine dyno testing.

K&N's are only very lightly oiled, ran one for ages in my MY99 with no problems.

Old ITG, Ramair were foam and covered in a thick sludge.

HKS and Blitz SUS could not filter a brick.

ex-webby

Mike,
Nope wasnt any leaning of mixture..... AFR's were exactly the same on the wideband sensor. Believe me...... we checked everything. We even put a brand new OEM filter in to check it was like for like (i.e. new vs new).

Shaun.

Shaun what filter/filters did u test to give u the 8bhp gain ??
