Hi. I have WRX with PPP, would anyone know if it is worth putting an induction kit on the car. Still has standard air box at the moment. And if I do will I need a remap done. Or should I just leave it as it is.

Many Thanks

Definatly get a induction kit and a remap, you'll get about 30-40 bhp gain from a simple upgrade.

Agreed Have one put one on mine with a PPP. Not affected the car really or that I would notice. But looks and sound's better IMHO

Can I get away with not having a remap by just putting it on though ?

Yeah It will be fine mate. I would go for a K&N or Pipecross, cost a bit more but alot better filter's. And you will get the bit of pipe for your MAFS to screw into, without having to bodge anything up.
