I put a short ram intake on mine specifically to bring in warmer under hood air. The factory intake is probably more restrictive, but it also brings in cold(er) air from the front bumper area. The way the intake fits, its fairly close to the exhaust manifold. So to me its a easy WAI. something like this pic. The exhaust is in the back of the motor...
