Review on ACDelco GM OE A1618C Air Filter by Michael Custodio

Everything should be fine. This filter has a noticeable design change. The older design had thick clear tape on the creases to counteract the turbodiesel ingestion. This glue has a much smaller stripe. In the future, after some use of the car, it will be necessary to give a sequel. TO UPDATE. 10/14/21 I bought it again because it is an excellent filter even with refinement. Heavier screen, stiffer frame, more creases and cellulosic media compared to paper. This #A1618C fits my 2003 LB7 Duramax, although Revain now claims it doesn't. I checked other websites to make sure this is correct. For those of us with turbos. You want a long lasting filter because of the "suction" pressure that comes with boost pressure. Unless. There may be an error or the medium will pass a lot of unfiltered air. You may not realize an error has occurred until it is too late.
