What is PPP?
 

Yes I have searched but I can't find anything ?

Unless you mean The language that enables a computer to use telephone lines and a modem to connect to the internet? but I'm sure this wouldn't make an Impreza faster:iamwithst

Prodrive Performance Pack

Dont think you've really searched have you - there millions of threads :(

Yes that was a bit of a fib wasn't it. :)

I typed in PPP and went though two pages of titles, nothing mentioned what it is :(

so dare I ask what is involved ?

Hi,

Dependant on model and year....

Remap or ECU
Exhaust system (with sports cat and backbox)
Intercooler Pipe
Uprated fuel pump

The above are mods in their intirety, so will be a varying combination from model to model and maybe year dependant.

Combination of parts will give increases in power and torque. This is the only Subaru official and warranteed way of doing this.

Regards,
Shaun.
