With the pod filter, you'll have to make sure it's getting 100% cold air from the front of the car (and not hot air from the engine bay) otherwise you'll find that whilst it sounds nice you'll actually lose power.
take this advice seriously, ppl dont realise how much power they actually lose from hot air, 100% hot air loses u like 5kws and 100% cold air gains u about 2-7kws depending on ur setup
for a good pod setup set it up like one of these:
this one is a bit of work, u relocate the battery, box in a pod filter and keep the front open so it gets the cold air coming over the headlight,

straight up piped to a pod filter down behind the bumper, Iced (henry) on mlga sells this kit for around $250, but its worth it, just watch out for puddles

this is my setup, fully enclose pod in the engine bay, snorkel down to the front grill, cost $150 very good kit for cost, and its a k&n filter (which is top of the line)
you will need to remove the lower resonator for this, which is easy and the resonator is a useless plastic box, a few bolts and its off (located under ur stock filter box infront of ur front left tyre)

easiest setup: josh has this one, keep ur factory airbox, either upgrade to a k&n pannel filter (cost ~$100) and remove the useless resonator, then use a $20 flexi pipe from autobarn to pipe it to your grill, optionally add funnel to the end for better air gain at speeds

so yeh that covers most of the ways u can do it, the more cold air it gets the better gains u will get
also get extractors (cost $450 but are so worth it) extractors replace the exhaust manifold (bit at front of ur engine that continues to ur cat-pipe-muffler) extractors give way better flow
other easy things, remove the coolant lines from ur thottle body, they heat up the throttle with hot coolant (to prevent freezing the TB in icey countries) which heats up the air going into ur engine
u basically just loop the coolant line back into the motor
ontop of that upgrade ur thottle body, well worth power mod
peace out
