Alright ,
Can anyone tell me what is a good induction kit for the impreza turbo ? I was looking at Powertec and HKS .......open for ideas
cheers

 

K&N and Apexi are both good for the scoob, avoid most others

 

Green panel filter ........

 

keep ya panel filter unlees ya got fmic then i say apexi

 

What MY are you thinking of fitting this to? Certain model years are prone to killing the MAF if an induction kit is fitted, which can lead to expensive engine damage. Certain induction kits are worse than others. I'd suggest a detailed search before doing anything. The gains are FAR outweighed by the losses in quite a few cases.

Talk to a few guys on here who've had Scoobs for years, and take advice of respected tuners, like API, Power Station, TSL, Graham Goode, Roger Clark Motors, BRD, Scoobyclinic, among others. Those guys will give UNBIASED EXPERT advice, not just try and sell you something.

Don't go for the HKS, had one on my MY00 Turbo and went through MAFs like Jodie Marsh goes through men

I changed to the K&N and that was a lot better.

I've now got a K&N Panel filter on my MY05 STi and is excellent

K&N all the way

this may help

 

HKS are meant to be fine on early models from 1993 -1996 without any problems at all. Ive had one on my V2 STI with no issues.

On later models the air flow meter is more sensitive i believe so the HKS just blows them.

Its not the the HKS is Crap its far two advanced and let too much air in too quickly and has a oiled based filter which can cause issues to the air flow meter by sticking to it.

So the later models are better with filters which cause more resistant to airflow like K/N & Apexi which are cotton gauge types that wont let too much air in at high speeds to blow it.

But i ve been told that the new HKS Reloaded kit uses a Dry Filter system so they are meant to be better for later cars.

Thats my view anyway but im sure someone will correct me later!

Define excellent? It makes a good noise, or it enhances performance?

I had a 'Trust' kit on mine and when Richard Bulmer mapped it we took it off and replaced it with a green cotton filter. The intake temp immediately went down by 14 degrees meaning the induction kit was actually detremental to performance in this case.

 

Gary,

It was the first mod I had and the throttle response was significantly better as well as a little more power. Noisewise, I didn't notice much of a difference tbh.

I don't think I'd go for an induction kit at the moment but would opt for a wing mounted one like the Typhoon to reduce the intake temp if I did get one.

 

could someone explain to a thicky what the difference is between a air filter and a filter panel

 

The OE filter on the Scoob is inside a box, known as the airbox, or filter box, the upper half of the box is seperated from the lower by the filter: a "panel". Air flows up through the filter and out at the top edge to the intake. The intake is cooler air from under the wing and the front edge of the bonnet.

Induction kits tend to use a cone shaped filter which just draws air from all around it, another drawback as it pulls in hot air from under the bonnet.

The same thing. They both go in the standard filter box.

Induction kits are parts used as a replacement for the filter box and filter.

Mervil, When someone ''proves'' to me that an induction kit provides more power or torque on an otherwise standard car then I will believe they are with the money..... Till that time comes I will believe they are a total waste of £250 or whatever they cost.

 

I'd recommend the APS one.

 

Unless it is a Cold Air Kit, and then is located in the inner wing, drawing only cold air. (APS/K&N Typhoon)
