So I decided to put in a cylindrical Spectre air filter, is this bad for turbo? on 1998 Volvo V70 XC

I had a standard rectangular air filter for awhile, then put in a K&N air filter but i decided to go with the round Spectre Because in my jeep it game me more power and better gas milage, but now I'm starting to second guess myself because I don't know if it will do anything to the engine or affect the turbo?

Hard to beat OEM thats just my opinion. Unless modifying a lot more stuff.
Thanks! well I plan on modifying more, I actually bought a new cup from GForce thats suppose to get me more power and mpg.
