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.

Bouncy and cool
Size: Queen (Mid Loft), Number of Items: 1
I had been searching for a new pillow for weeks, but nothing was calling to me. So many go flat far too fast, and most cooling pillows are lumpy as can be. This one is perfect. Doesn't go flat, gives me comfortable support, and actually keeps cool longer than the average pillow

Needs to outgas for a day or two and then its great.
Size: Queen (Mid Loft), Number of Items: 1
Needs to outgas for a couple days, ideally outside on a clothes line. Having said that its the first pillow out of a half dozen Ive bought in the last 18 mos that I can sleep on. Sleeping much better and longer now. Latex foam is the only pillow for me. I swear I searched on here a year or so ago and could not find one.

Goldilocks pillow
Size: Queen (Mid Loft), Number of Items: 1
I tried 5 different latex pillows, 2 from this brand. Most had to much loft and were too firm. This brand has one called extra soft that was comfortable but a little too soft. BUT, I could tell the latex was better so I tried this one. It strikes the perfect balance of support and is not too firm. Compared to all the other brands I would call this one soft/medium as all others "medium" were pretty firm. This one is just right!

Perfect supportive soft pillow
Size: Queen (Mid Loft), Number of Items: 1
The perfect pillow that is hypoallergenic. It’s soft but your head doesn’t sink through. Supportive and soft at the same time. Have bought more pillows.

Very firm pillow
Size: Queen (Mid Loft), Number of Items: 1
I'm not sure I received the same pillow as advertised. The pillows I received are extremely firm. I would not classify it as medium. It was also not covered by a cotton case. it had a very sheer gauze like material covering the latex.
