Air filter thickness

[Dacha]

I replaced air filter for the first time on Stihl ms 170.

I bought oem kit: air filter, spark plug, fuel filter from Stihl dealer.

Now the new air filter is twice as thick as old one.

When i put on top plastic cover (shroud) it is hard to close. I have to press fairly hard on cover to be able to turn the locking lever catch.

I guess i should just ignore it and leave it as is ?

Any suggestions.


I washed old air filter, left it to dry, and stored it as a spare...
