Is there an aftermarket airfilter for the HHR SS?

Also is there any way to make the Blow off louder?

 

Could probably just buy a universal cone filter and mate it to the stock intake.

 

and suck hot air and lose torque. You need an enclosed system so it's a real cold air intake. I've seen torque loss on the dyno with just an open intake.....If you want a louder bov you'll have to go aftermarket like an HKS, Tial, TurboXS....

 

Air goes through the FMIC anyway. The increased airflow would decrease turbo lag.

White,

have you tried a MBC yet? What are your A/R's like on the dyno?
