I found an older forum about this, but does anybody currently have the Mugen or GruppeM airbox?
I know the majority of people here favour the Injen CAI, but I really don't want to lose any bottom end: towing a trailer is a necessary part of life for me so I want to boost the low-mid range without losing any of the top end -- which I believe the Mugen box especially is supposed to do.
If anybody is using either airbox, how did you find them compared to stock?
