I am wanting to change my standard WRX bonnet scoop to an STI one and was wondering if all I have to change is the scoop itself?

Is there a different undertray or something I have to change too or is it just the scoop part?

Its an 03 blob I have. Need to source a scoop first though!!

Thanks.

If you still have the WRX intercooler then your undertray will be fine.

Thanks for the response, so if I where to change the intercooler to one from an STI then I would need the relevant under tray.
What benefit would I get from the STI intercooler if I where to swop over?

Yes if you were to change the intercooler you would need the correspoding undertray to get the best out of it, as the WRX tray wont cover the whole of the intercooler.

Without a remap the benefits of fitting the STI TMIC will be minimal, however with a map it will allow more boost to be dialled in.

As above! lol. My question is this, why change the scoop only? There is nothing to be gained from just doing that apart from an emptier pocket money wise.
Unless as I, and others do, you change the intercooler for an STi one, in which case you get the undertray, bonnet scoop, etc.

One thing at a time I suppose. The main reason just now being for aesthetics. I want to do all these things one day its just a matter a cash

Oh, would I need a remap if I swopped intercoolers? One is planned one day but if I swopped before is it neccessary?

tbh, I am not sure if you would need a remap immediately, although I was advised to be careful until I had my remap done. Someone will reply with the correct info i am sure!
Ahh, the modding bug, such fun

i read on another thread that if you change intercoolers you should get a remap as it can cause boost issues. if i can find the other thread i'll post a link to it

cheers

I swopped my newage intercooler for an STI one, had it on the car for a couple of years without map,I would say a remap is not needed if this is the only thing you have changed, but to get the most out of it you would.

had mine with an sti on for nearly 5 years without a remap.. still going strong at 137500 miles

Why bother changing it if you aint gonna remap? There is no benefit surely.
