AEV’s Diesel Particulate Filter Replacement Tube is designed to fit with the AEV Drop Brackets and is made of the same high-quality stainless steel tubing as the stock unit.

2011 Diesel Wranglers now come standard with a Diesel Particulate Filter (DPF) in virtually all export markets. The stock pressure differential switch tube interferes with the AEV Drop Brackets included with our popular 3.5” and 4.5” DualSport Suspension Systems and needs to be modified in order to install the Drop Brackets.

Customers in export markets should be aware of the diesel particulate trap when purchasing or installing an AEV 3.5″ or 4.5″ DualSport Suspension System. This new part can be purchased separately and is required to complete the suspension installation on vehicles equipped with the DPF.

Note: While most diesel Wranglers do have a DPF, those that do not still have what appears to be a DPF, only without any sensors screwed into the bungs, essentially an “empty” DPF housing is still in the exhaust. Vehicles with no sensors screwed in to the front of the DPF housing do not need the AEV DPF tube.
