Could anyone tell me exactly what they change when they put a PPP kit onto a 04 WRX, thanks

 

I am currently considering PPP on my MY04, and would like to know the differences between that and the MY03 PPP, as I only have stats for the MY03 PPP.

Does anyone know the answer?

Thanks,
Kev

 

03 & 04 PPP kits for WRx are exactly the same. It was only for 01 -02my's that the pack offered little bhp difference.

The 03/04 pack includes:
Rear silencer box & Mid section exhaust.
Silicon intercooler hose.
Modified ECU.

Hey presto, 1600 quid lighter!

 

... and ask for your old bits back! You'll get the back box and cat.

Not sure how useful they'll be in the future, but they do belong to you.

 

I take it they do not increase the boost pressure then ?

 

The modified ecu should take care of that.
