It's the Hyperflow MONSTER intercooler for the MY01-05 Impreza. You can buy yhe cooler with or with out the mounting bar at the top but with the 2 being the same price you may as well get it with and make it work or if you can't then cut it off and you have lost nothing. It is a massive cooler at : 760 x 250 x 114 [mm] and works very very well.

Hi my sons car has 604 hp from a gt35 on straight v power he is using modified sti heads with variable cam timing and solaris ecu, standard entry intake,standard top feed fuel rails, still has aircon it makes that at 2 bar on a 2.5 the heads are well worked with cosworth cams but they are standard late sti heads with some porting/ect got to be cheaper than cosworth heads and obviously do the job,

Yes it is bar and plate but seems to work very well. The preshure drop on this intercooler is about the best i have seen and another major factor in buying this was the cost, lets just say i could not go wrong.

V4 ported heads, new valvetrain, billet cosworth/kelford cams optionally converted to later style shimless buckets.
650hp capable heads, done!

Same with P2.
I bought a complete STI4 engine with a bottom end issue for £450. It was a no brainer. Not only did I get the heads but I also got everything else I'll need to build the engine.
The only thing is I ordered the S6GP thiniking that we were going to use AVCS heads and have a bespoke wiring loom. Where as now an S6pnp would be perfect, never mind.
