Pod filters are nasty. Good for throttle response but will pull a lot of radiant heat from the engine bay (bad for air intake temps). They also have a habit of sucking in crumbling air filter element when they get old. If you can adapt a good quality, cleanable filter into the stock air box you'll be better off. If you want to get all off-roadish, maybe install a filter snorkel on your truck.
Won't be something you'd see everyday on a DR50!
