Has anybody had any experience with these? are they worth spending the extra ££££'s over the Super Powerflow Filter kit ? does it give you more power than the cheaper version as they claim?

Don't quote me on this but i think the racing suction kit is only available for certain Imprezas
Give RC a ring 01925575290

 

I just had the SPF installed and it really makes a difference (apart from the noise). If the racing version is better then I would really recommend it. Otherwise go for the standard it's still cool.

How much noiser is it?

 

Under hard driving: a lot
Under normal driving: a bit

Whistles with your foot on the accelerator, this gets louder the more you give it. On a gear change it sounds like there's a pretty major dump fitted.

what about motorway cruising at speed?

 

There was a thread recently with a link to the GTR owners club. There was a test of 4 filters - apexi, Blitz, HKS and K&N.

The Blitz and HKS weren't worth having on

They do give good gains, but at the expense of?

 

If they give good gains then why arent they worth having?? they dont cost much more than other certain brands I can think of

 

Jake,

When I say they weren't worth having on, I was referring to filtration - they basically stop bugger all!

Interestingly, the Apexi filtered better than any of them, but also produced the best results.

K&N was 2nd.

 

I have the HKS Racing Suction Kit on my scooby - I think it is great - makes a lovely wooshing noise, and I did notice a slight increase in performance over the Monster Racing Suction Kit that I had.

 

do they do one for MY94 cars?

does it retain MAF sensor and gubbins? cos if not then no good.

currently got HKS super power flow induction kit, which is nice!

 

Markus,

HKS only make Racing Suction Kit from MY96/9 and up.
