Right, after much researching, speaking to all the top Companies and Specialists in the UK about what the best/safest Induction Kit is, I have whittled it down.
I did consider the APS Cold Air Kit, but there are none available anywhere in the country, and there won't be for some time. The K&N Typhoon kit is similiar, but not available for Imprezas.

After speaking to Olly Clark at Roger Clark Motorsport, he suggested the RCM01/RCM04 Kit.

Unlike the APS Kit, this kit does NOT require a re-map after fitting and is totally MAF friendly. Although it does not fit into the inner wing like the APS kit where the air is cooler, it has a much larger Cone Filter and therefore has a much better and bigger air flow. This is the kit of choice for all their project & Rally cars. It also produces a nice induction roar and makes the wastegate clatter and dumpvalve more audible, like a rally car. Despite this, it is not over the top like some Blitz items.

The kit is cheaper as well, coming in at £144+VAT, but of course they are willing to give us a good Group Buy price.

The Graham Goode Racing Induction Kit retails for £144.60+VAT. This kit is similar to the RGM kit, but GGR are not keen on Group Buys and would only consider it.

I have spoken to Andy F. for advice.

Add interested names and Impreza model on the list:

I spoke to Andy F. yesterday about Induction Kits, and he said that APS does get more access to cold air alot more freely. The likes of the RCM kits might suffer from some heat soak in very hot weather when stuck in like traffic for a while. Its fine when the cars moving however. This can be compensated by fitting a cold air feeder through the wing sourcing cold air in the same area as the APS kit does. With the RCM / GGR kits, the Induction roar, wastegate chatter & dumpvalve will be alot more audible(like a WRC car), unlike the APS, which will be quite quiet due to its location within the wing.
The APS kit also uses a small K&N cone, whethers the RCM /GGR kits have a massive K&N cone, therefore allowing more air flow.

I think, in my opinion, the RCM with a Cold Air Feeder Kit (which retails for an extra £16 - which I'm sure we could get thrown in with the deal) would be the best compremise, as you get all the Cold Air benefits, that the APS kit gets, by fitting the Cold Air Feeder, plus you get the benefits of the increased air flow with the bigger cone and the Rally car noise that comes with it.
RCM use this kit in the World Record Icelandic Team Scoob and it doesn't seem to suffer from heat soak.

Hope this helps some if you guys that were only considering the APS kit. Like I said, the main supplier, G-Force, told me they they had no gurantee they were getting any more Cold Air kits in for the Classic, as APS are no longer making the kit, and are depleting their stocks.

did you try lateral performance first?

Will these fit a 2005 car?

What's that Adam. Lateral Performance for an RCMS kit???

no harvey,

I was referring to the spun aluminium trumpet and K and N cone filter that they sell.

The fact that the RCM kit has been considered the one to go for over the GGR kit, and the APS CAK suggest that options are being considered, seemingly dependent on price.

did you try lateral performance first?I did, just waiting for them to get back to me.

Its basically the same kit though isnt it?

Both K&N filter and both come with the trumpet.

Lateral buys from RCM and RCM buys from Lateral.

RCM also buys from GGR

In the end its probably the same kit by 3 different suppliers

Just depends who comes up cheapest :D

I did a group buy with GGR for their induction kits a couple of months ago and service was spot on and everyone got a good deal and next day delivery

The GGR seems to be the one to go for and Moneys the man for getting them cheap!
