These spacers will definitely clear your light for awhile, but they way that they're constructed, the cap that screws the min cat into place will fall off on its own after a short period of time and the code will come back shortly after then. The only way we've managed to keep them in place has been tack welding them, but this extra step shouldn't be necessary right out of the box. We've installed about 15 of these and all 15 of them have resulted in the same issue.
