View Full Version : K&N Induction - Cold Pipe ?

1st November 2000, 11:28
I've recently fitted a K&N Induction Kit to my MY96 Turbo, and was wondering if anybody has fitted one or had one fitted ?
The reason is I haven't got a clue where to route the cold air pipe from the cone to the front of the car.

Any suggestions...

I am interested in fitting the same to my MY96 wagon...

Pleased with the results?

Yep I'm very pleased with the increase in pull, extra top end (i.e. pulls right up to the red line) e.t.c.
The only thing I'm not overjoyed with is the noise from the dump valve. I've got used to it now, but the recirculating dump valve can now be heard 'VERY' clearly, with a flutter type release rather than the athmospheric type release.

If you can get to hear one before you buy it, I would do. On the Post97 models the dump valve can not be heard half as much.

But they are all the lovely noises that you want to hear!

The MR2 Turbo I had before the Impreza had a HKS dump valve on it which dumped all the pressure from the turbo when you took your foot off the power into the engine bay (behind your head) with a loud "Crrrpuuusst"
as the air rushed out! Got a lot of strange looks mind as you changed gear...

Not really a churp with a induction kit, more a flutter. Doesn't sound half as good.

Debatable whether a cold air inlet does anything or not.

People always say that underbonnet temps are more, but when moving forwards at decent speed I doubt theres much in it.

Far more efficiency can be gained by improving intercooler performance, since the end temperature of the mixture entering the engine has more to do with the turbo heating it up and intercooler trying to remove the heat.

This was the conclusion on the Scoobynet (sorry bad word http://bbs.22b.com/ubb/smile.gif). With forward motion the air intake would be cold enough.

I have just fitted a 57i to my STi II '95, I know the instructions suggestd using the cold air pipe, but you must be joking, I cannot see any where for this to go! But as the filter is right by the original cold air feed, I guess that we should be okay?

By the way I also agree about the noise, not really that nice it is http://bbs.22b.com/ubb/frown.gif

You get used to the sound... even my better half has stopped complaining about it.

Still prefer the short sharp chirp of an athmospheric BOV.
