Billet 4 Coolant Mod Subaru EJ Engines EJ20 EJ25 WRX STI Forester XT Legacy GT4 Coolant Mod Subaru EJ Engines EJ20 EJ25 4 Coolant Mod for Subaru EJ Engines was designed to increase coolant flow to cylinder #4 head area. The additional coolant flow helps reduce cylinder #4 coolant temps and keeps the temps more uniform with the rest of the cylinders. This helps reduce knock and detonation in cylinder #4, which is known to cause the dreaded EJ ringland failure. CNC'd 6061 Billet Aluminum Fittings Black Anodized Multi Layer

Ideal fit for man parts
Color: Light Khaki, Size: 34W x 32L
Phenomenal fit, honestly one of the first pairs of khakis that doesn’t encroach on my nether regions, moves very well very lightweight. If these pants are durable, and last, I will definitely be buying another pair.

Nice pants, run a bit long
Color: Black, Size: 38W x 30L
These are nice formal dress pants. They look proper, have a nice pleat, and sit nicely on the waist and legs.
My only complaint is that they run a bit longer than expected. I get the same size pants everywhere so I'm used to the size, but these definitely run longer than expected.
The material of the pants is okay, it's not going to be your typical wool slacks or anything, and it feels a bit "plasticky" at times, but they look great, and the polyester definitely helps with the wrinkle avoidance so you do not need to iron these.
The description says "soft premium fabric" but it's 100% polyester, so take that as you will.
Overall very decent dress slacks, at a very decent price.
