Workhorse Heavy Duty Intakes deliver the most flow and power for Diesel and Big-Block trucks & SUVs.

The DRYFLOW Synthetic filter is independently at 99.4% cumulative efficiency and traps particulate down to one micron in size (based on SAE J276 JUN93 Fine Dust Air Cleaner Test Code procedures)
AEM's unique non-woven synthetic filter media never needs oil! This means less down time between cleanings and no more chance of over-oiling, which could foul sensors along the inlet path and void vehicle warranty.
