Looking to replace standard air filter on multi air 105.

Obviously not going to be much if any performance increase just looking to smooth the acceleration more.

Any advice on which make is best, looking at bmc and k&n.
Will replacing do what I'm hoping?

Thanks

doesn't really matter what filter you use, BMC or K&N, but the BMC is used in the Abarth SS (IIRC) so I'd be leaning towards that one.

As for smoother acceleration, I had a test drive in the 105 multiair and I didn't notice any sluggish acceleration. A filter will help, but a full stainless would also help your acceleration.

BMC... but it really all comes down to personal preference.
