Does anyone know which K&N Air Filter will fit a BH5 Legacy???

[Guest loren]

Why not just dispense with the filter all together?

I saw an escort race car that ran 4 throttles and no filters. The owner said

he had never run filters in any of his cars and never had trouble.

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

Yea it does have a AFM unfortunately...think il just buy a normal Subaru panel filter from the dealer.

Then u hear stories like this

"I worked for race teams for years. One Toyota Atlantic teem I worked on the driver thought the car was lossing power from the start of a race to the end. So we did leak down checks when we got new engines in. 3% leak down- New. At the end of a race we checked it again and we got 29% leak down. So we sent the head to get the valves done and checked the leak down when the head returned. 4%- Leak down. At the end of the next race 31%- leak down. So we put three dabs of grease down streem of the air filter. "K&N" The next engine came in with 3%-leak down new. And at the end of the race 32%- leak down and the dabs of greas were full of grit. So we changed the filter to a oiled fome filter. 3%- leak down new and at the end of the next race? 18%-leak down. Better still not good. So we made a new air box and used a Mustang GT stock air filter. 3%-leak down new at the end of the next race? 1%- leak down yes I said "1%". The rings bed in and the engine seals up. We went from changing a engine at 300 miles with 29 to 34% leak down to. Changing the engine at 800 miles with 7% leak down.

Can we get pipecross filters here in NZ, and what do you guys think of them? They're pretty good when it comes to bikes, and spank K&N no problem for power gains...

[Guest boostin]

Just use the stock airbox and filter, and open up the piping to it. Marley intake ftw!!

What do u guys think of the 'white air intake mod' in pic 9?

Make any difference?

[Guest boostin]

That will just scoop more cold air into the intake pipe.

And more bees. After driving Taupo to Whakatane via murupara at dusk, i have to shake all of the wildlife out of my air filter and radiator.

Its a cheap mod. Cant hurt to try it.

Ha yea i always seem to get butterflys and bees in my radiator..

Any ideas on what he used?

Looks like a bit of bent plastic screwed into place.

Could just be some painted sheet stainless. Nothing too fancy. Id remove that resonator from your intake first. That only requires a bit of pipe.

Yea that could be fun! ;D

Do u think itl change/improve airflow/noise?

[Guest keltik]

Removing the resonator will improve the noise a bit. Makes it look cooler too.

Sweet as! btw im keen on getting 2 of those front pioneer speakers 8)

Not sure about that particular example but often resonators attached to the intake pipe are there for good reason - for example its well known in MX5 circles that if you remove the resonator from an otherwise standard car it'll develop a flat spot/dip in the torque curve around 4000rpm.

Generally more an issue for NA cars than turbos, so if you do remove it from the TSR try and make it reversible in case you find out what it does and want to put it back again.

Cheers man. Yea will definitely make it so its reversible.
