For all the ones getting ready to install their new louvers. Make sure to place the louvers on the glass with the trunk lid fully opened. Move the louvers down close to the lid but not so low as to bump the lid as it opens and closes. Then make your marks for proper placement. I had mine completely installed before I discovered I couldn't open my trunk lid fully cause the louvers were 1/4 inch too low. The directions do not warn of that. Other than that small glitch in the installation it's been a great product.
