Sti top mount on wrx
 

I've got an sti tmic to fit to my blob wrx, do I need to fit an sti scoop and undertray?

I'm assuming the sti undertray is bigger? would this fit with the standard scoop?

You will need to fit the STI undertray to get the most possible air to your top mount... You can keep with the standard scoop although having the bigger Sti one allows for more air to pass through which will always be of benefit

if you haven't got the bigger undertray your better to run no undertray rather than use the WRX one. look at it compared to the size off the intercooler - a good 2 inches on the left of the intercooler are totally obscured by the WRX tray.

Fingers crossed I'm getting both, but il get the undertray either way

Sti tmic fits on the same brackets?

Does anyone have a pic of both undertrays side by side?

sti topmount fits on the same bracket on the right hand side, the left hand side it uses the same bracket but the left hand hole instead of the right hand hole like your WRX intercooler.

the trays are the same except that the opening and the shroud are wider on the STI one to accommodate the wider intercooler area.

where can I find an STI TMIC and undertray for my WRX?
