I had a knockoff injen intake on my FG2 before. The aluminum piping was good in quality. I didn't trust the filter or the heater hoses so I bought an Injen filter and heater hoses from Pepboys.
The only concerns with this product can be the fitment, sketchy air filter, hoses, and maybe the couplers. You'll end up spending an extra $75-$100 to complete that setup.
