air filters that are supposed to let more air in compared to stock (like K&N) use filter material with bigger holes

nothing to worry about

it takes more than particulates to harm an engine

before (the Libis days) i would drive around with no air filter

one headlight removed, air goes directly into the air intake tube

the faster i drive, the more air gets rammed into the intake, the more power i get (fun )

did that for quite a while

no damage to the engine

put the filter and headlight back when i sold the car

hehe
