I want to install a CAI in my 451 Passion 2015 and I see the ones at Smart Madness, Is it worth it?
And also I see there that wont fit in the Turbo models, is that true ?
The CAI from Smart Madness is for the N/A 451 smarts only. The turbo 451 was never offered in the US so you would have to shop a vendor in Europe to get what you want.
