Do you need to take your snorkel-less Mitsubishi Pajero / Shogun / Montero on dusty roads and don't want a blocked air filter after 5000km?? See how to create a cheap, simple and washable pre-filter to stop most of that dust before it gets into your air filter! Same idea as a 'Unifilter' for vehicles with a snorkel, but works on the Pajero without a snorkel!
