AIR INTAKE
An upgraded intake allows air to flow more freely to the intake manifold. More air is allowed into the engine, which in theory increases your power. It has been shown that the stock airbox in the MSP is surprisingly adequate, but small gains can be had by upgrading the intake. Plus, a nice intake looks much better than the stock airbox, and will earn you extra points at a show. You're car will be louder, and the gobble from the BPV will be more noticable when an intake is installed.

An upgraded FMIC (Front Mounted Intercooler) will greatly cool the air going into the engine. The turbo generates a lot of heat, and the air coming out of it is hot as well. The intercooler is placed after the turbocharger to cool this hot air down. The stock MSP intercooler is tiny and inefficient, and gets heatsoaked very easily. An upgraded intercooler will help an already modded MSP very much. Gains will also be made with a stock MSP, but an FMIC is a rather costly item and produces larger power gains with an already modified car.

Hardpipes replace the stock (plastic) intercooler pipes with metal.
