BorgWarner S475 S400SX4 75mm Compressor Wheel – Blade Fins Intake, Part 171691

This is a BorgWarner 75mm compressor wheel, part number 171691, and it’s meant for the S475 or S400SX4 turbos.

It’s brand new but might not come in the original box—still, no signs of wear or use.

The fins are clean, ready to move some serious air.

It’s an OE spec part, so it’s a direct replacement or upgrade for certain setups.

Also cross-references with 171702, 176806, 171703, and 176807.

Made in the USA, no warranty, but it’s BorgWarner, so you know it’s quality.

If you’re rebuilding or upgrading a turbo, this wheel is a solid pick.
