Replace original X1 Series regulator internals with the conversion kit of your choice (Part #'s 13013, 13014, and 13015) and you have a regulator with vastly different characteristics. While versatility is one of the X1's greatest assets, it is far from the only new design feature. Utilizing larger (3) -8AN ORB inlet/outlet/return ports to accommodate increased flow, at the same time Aeromotive reduced overall size and the weight by 33% (compared to Aeromotive 13109 regulator). The new X1 design eliminates the compromise common to other convertible regulator designs, with the optimization of all internal components including the diaphragm/poppet, spring and bypass seat, the X1 delivers all of the performance and features you expect from an application specific bypass regulator, regardless of what you decide to do with you r induction system tomorrow. Above and beyond the expected performance, you still have the amenities like a 1/8 NPT gauge port and 1:1 ratio boost reference port for forced induction applications. Base fuel pressure adjustable from 35-75 PSI. Vacuum/boost reference capability. 1:1 rising rate for forced induction engines. Gasoline, ethanol, and alcohol compatible. (2) ORB-08 inlet/outlet ports on the sides. (1) ORB-08 return port on the bottom. (1) 1/8 NPT Gauge port with plug. 1/16 NPT Boost port with 5/32 hose barb. 0.188 bypass with matching spring and poppet. Handles up to 150 GPH with AN-08 return line. Suitable for any Aeromotive pump up to A1000. Mounting bracket included.

Fists a perfect in my 21 GCL
Great quality and very sturdy. Perfect fit in my 21 GCL. I will be interested in seeing if it cuts down on the amount of dust in the car.

Won’t fit.
Does not fit 2023 Jeep Grand Cherokee Laredo . If it could be forced into slot it would be difficult to remove. The air flow direction is not marked on the filter or packaging.

Excellent fit for my 2023 Grand Cherokee limited l
Not sure why others are saying airflow is decreased or it doesn't fit if they apply it to the correct vehicle. I have a 2023 Grand Cherokee Lmited L and it took me all of 5 minutes to change out the filter and I have to say, this filter is much better quality than the Mopar filter that was in there. There's absolutely no decrease in air flow and it's like a custom fit in the space. The hardest part about the entire process was emptying out the darn glove box!
