I think with normal use or maski severe pa the normal life span ng vehicle wala pa obvious at noticeable negative effect ang inadequate filtration ng k&n at least to majority of users.Nabebenta na bago pa mag loko but to those mechanically inclined tulad nun na erode na turbo impeller blade ng nissan navara (hurricanr filter ata iyon) dito sa tsikot meron talaga detrimental effect though the severity varies greatly with usage.
