Just a replacement K&N Air filter not a pod filter.

I don't dislike them, I just don't think they improve the air flow.

K so u reckon their is no difference between a k&n one and a stock one.

Anyone know where I can buy a new one?

KN33-2031-2

the K&N ones are all right the only advantage is being abile to clean them that iv found. did notice that the oil mad my b4 run like sh!t untill i cleaned the afm. no problems since. if you want beter air flow do a snorkelectomy found it helps a litle bit nd sounds mean

k cheers bro how hard is it 2 clean the a.f.m?

[dvs-b4]

i just used the crc maf cleaner seemed to do the trick

Snorkelectomy achieves bugger all on a BH except for more noise, makes a difference on a BG though apparently.

Cleaning MAF is a piece of cake - 1)buy can of CRC MAF cleaner 2)remove maf part of airbox 3)spray MAF well with cleaner 4)let it dry and reinstall.

Re performance gains, I was reading a story on another forum recently from a guy who dynoed a GrpN Evo 9 with the standard filter and a K & N filter - it made 15hp less with the K & N than it did with a standard filter, and the standard one also filtered dust more effectively.

On the dyno at Keith Stewarts last year, I think Albaru got more power with a stock paper filter than his K&N?

Personally i wouldnt bother with a replacement panel. I just put my airbox back in so have a pod filter sitting in the shed now.

New subaru genuine panels are only about $30. They seem to give best performance vs filtration.

Redline have HKS replacement panels for $100...

Got one, it seems okay, probably doesnt filter as well as the standard ones though.

Every independent test i have seen - K&N does not filter as well as a paper filter.

There are gains to be made with airbox / snorkel mods on a BH. The BH snorkel is a more freeflowing design than the BG. So the gains from removing the snorkel aren't as much. The BH airbox entry is still a restriction.

Also invest in a Jigsaw and make that 'hole a hole lot bigger ;D

But the intake pipe under the manifold is narrower then the airbox inlet, and the turbo

inlet is only 2 inches or something.

[Guest]

True but it does reduce pressure drop thus aids flow.

But yes the TT turbo intake is restrictive but it has flowed 240kw or there abouts

[Guest keltik]

As the cars a TS-R...well...theres no intake pipe under the manifold or a turbo inlet

HAHAHA YEA IM TO COOL FOR ALL YOU FORCED INDUCTION PEOPLE LOL

CANT BEAT THE MIGHTY 2.0 NON-TURBO ;D

[subieboy]

I still vote chopping the airbox! ;D turbo or no turbo

[Guest boostin]

Does it have an AFM?? If not, I vote for pod filter straight onto the throttle body!! ;D
