K & N filter safe?

[RangerTrek7]

drop in filter ay yung pwede mung ipalit sa oem filter mo, without any modifications, as in ilalagay mu na lang sa air filter housing mu.

yung cone type ay yung hugis cone.

for update nakabili na ako ng E2296 Knn drop in filter. Almost a month use na, notice ko lang after replacement lumakas yung hatak at hissing sound especially from shifting gears to 2nd and 3rd.

Depends on what you call safe. More flow = less filtration. So you will be trading off engine longevity for performance.

Take note that the tests were done in a country much cleaner than ours.
