Air Filter and Fresh Air Intake

The DeLorean air filter element PN 102575 is located inside the black air box PN 101058 on top of the engine. The air filter should be inspected at every oil change and serviced at every major service interval (30,000 miles). In the case of a seldom-driven car, inspect the filter at least every calendar year.

Remove the three M6 bolts, [10mm hex], that hold the box in place and disconnect the Inlet Duct PN 105927 by pulling the plastic collar off of the air box, and the PCV (Positive Crankcase Vent) hose to lift the box away from the engine. Unclasp the four wire clamps PN 102581 that hold the box halves together to gain access to the element. Replace (or clean and oil, in the case of the reusable K&N) the air filter, put the box back together, and re-install the air box with the three mounting screws and washers. It's really a lot easier done than said. New filters, air boxes, clamps, DMC label, and inlet tubes are readily available.

There is a large o-ring around the air inlet on the engine PN 101059. Be sure it's still there.

There is a Performance Air Intake PN GT100200 hose available which replaces the paper duct, plastic tube, and preheat valve. This also eliminates the often-discolored metal preheat tube and rusty manifold heat stove. This is the same system included in the Stage 1 and Stage 2 Engine Kits. In July of 2026 this product received a major upgrade with the addition of a DeLorean-specific adapter tube we designed to improve the attachment and airflow. Earlier versions can be updated to the latest specification with a GT100200A kit. Both come with detailed installation instructions.
