CAN WE FIX OUR $9000 Audi B9 S4 WITH ALIEXPRESS PISTONS?
Our audi s4 has experienced piston skirt failure. We remove the engine and try our hand at some pistons we purchase off AliExpress to see if it's possible to fix it. B9 S4 and S5 Piston skirt failure is becoming increasingly common. The typical solution here is to replace the engine... but can we fix it without doing so? In this video I show b9 s4 or s5 engine removal, and the profit/losses of the project.
