I found that the intercooler hood scoop tended to scoop up leaves, bugs, and cigarette butts. Maybe it was just because I was doing a lot of driving in NJ (sorry). I saw a MINI catalog featuring a grille and thought I might try to make one myself. Putting a screen to keep the junk off of your intercooler will sacrifice a certain amount of air-flow and I suppose there is some risk of having snow and muck block it as well, but if it’s that cold out, I don’t think it will matter. I much rather have to stop to unclog the scoop than pay for a new intercooler. (And as I would later find out at the track, it helps keep the rubber klag out as well.)
Remove your air scoop by removing the two screws and two bolts that hold it on. Take care not to let the trim piece fall from the hood. There is a gap between the scoop and the trim piece that seems to have been built for this purpose. Trim a piece of cardboard to get the right shape then cut out a grille from a piece of $2 Gutter Guard from the Home Center. Paint the edges with flat black paint to prevent rust. If that’s too complicated for you, send me $5 and I’ll mail you one. Motor on.
