The Driver (Hot) Side 3" Intercooler Pipe replaces the 2 1/2" OEM piece with a full 3" pipe.

This part uses CNC machined flanges with double o-ring seals, comes supplied with new wire clip rings for both slip flanges, and uses an upgraded silicone hump boot with stainless steel t-bolt clamps to withstand higher boost pressures than stock to increase reliability and eliminate blown factory boots and horsepower robbing boost leaks. Finished in your choice of custom powder colors. Pairs best with emissions compliant tuning and upgraded drop in turbochargers for optimum performance gains.This Part Fits:

Absolute horrible quality
Color: Black, Size: Medium
Do not purchase this track suit even if its on sale. The fabric material is so cheap, it feels like a tacky uncomfortable plastic bottle that's been stretched out over your body. The stitching feels very off and the thickness is somehow too bulky and looks baggy and at the same time feels too tight. Do yourself a favor and avoid, I'm returning this product.

Satisfied
Size: XX-Large, Color: D Green
Typically buy these from coofandy. This was my first from jmierr. Great purchase. Good material. Great fit. Not super thin material or super thick. Good and comfortable. Would purchase again!

Solid 2pc set
Hubby recently had hip replacement surgery & needed some comfier clothes while he's recuperating.
These are really comfy but they fit well and the subtle stripe just looks a little more "put together" than a standard sweat suit. This isn't his normal style but he's becoming a fan 🙂
Wash and dry well- no special treatment and no wrinkling or shrinkage. Warm but not hot, seem to be well made... not seeing pilling or strings unraveling, etc 👍👍
