Looking for the correct factory air filter for your 1st Gen? This is what the factory installed on your truck while it was on the assembly line. Surprisingly, it also has better flow numbers than many aftermarket “performance” filters.
This filter will work on 1989-1992 Cummins 1st gens. This is NOT the filter for your 1993. Believe it or not, the filter for 1993 is different. Back to the story of a 1st Gen isn’t always a 1st Gen…..
Don’t skimp on cheaper filters and save a few dollars. Buy a filter manufactured by Cummins. They know what their engines need to remain legendary status. Their filer media also wont rip and ingest through your turbo like some of the aftermarket brands.
