Reading more on the website, it sounds like they give you a new bottom half of the airbox, a silicon hose to attach to it and an aluminum piece to mount down in the bumper.
Sadly for $499, compared to something like the GruppeM that isn't half bad.
That doesn't excuse that it's about $50 in parts though.
And if I'm gonna get raped, I at least want a new box cover with "Dinan" stamped on it. Sheesh, give me something at least.
Wonder if it keeps the charcoal filter in place?
