l have more than one question first, is it ok to put a wrx Carbon fiber hood on to a 2.5 rs. Like will it fit, will water seep into the car from the open hood vent or is water not a problem, do all of the carbon fiber hoods have the space for the front windshield wiper nozzels. Second putting locking pins on the the hood how do you put the locking pins on to the carbon fiber hood without cracking the hood.l have a wrx wing on the back l wanna purchase a carbon fiber trunk and put on the wing on to the carbon fiber trunk, is this possible. l am considering buying an Injen air filter and do any of you recommended it.

well l think it ok and its your car.

All the body parts, after market or OEM, made for an 04-05 WRX Will fit your car. As far as the water in the scoop, l would think it will be okay but the distributor is pretty close to being under the scoop. That and the alternator are the only things you have to worry about getting wet and the alternator is far from where the water will be. They should have the washer nozzle hole already but if not just measure, tape and drill. Not too complicated.
