Why did you have to remove it so many times? Mine has been in since 10k and I haven't ever had to remove it
Just little things here and there that require removing the cowl or crossover pipe. I think it's also just been the mods I've been installing as well as a run of bad luck.
Recently when I did crossover/turbo inlet install it blocked the clamps to the crossover pipe, servicing the GFB diverter valve same thing, the one time I accidently launched the ecu plastic clip into my crossover pipe by accident(while installing tranny mount powerflex bushing, had to basically dismember intake to the turbo elbow all over again) , installation of passenger mount pineapple slice as the hoses blocked access to the bolts.
Mishimoto seemed to be one of the more reccomened ones as well so I thought I'd give it a shot.
