I ran a gimmik motorsports inlet on my 03 for a little over 4 years with multiple turbos. Tdo4, vf39, the largest being the evo3 16g at 23 lbs of boost. I never had any issues. There were people in my local area using it on larger turbos and I know eventually it will collapse, just dont know exactly when. If you have plans to do a "big" turbo build I might suggest a hard inlet, but for your average bear it will work great. Also, just as a side note, a hard inlet requires the removal of the intake manifold. Just something to think about when installing or paying someone to install it. Good luck!
