This item fits perfectly! Beware of knock offs that do not fit. Before I bought this TBB, I bought a similar one (silicone TBB) off someone on ebay. I received it and installed it. Though it looked similar, it did not fit properly; I could not install the plastic cover back on and the hood would not close. Also, the electric fan was hitting the plastic turbo pipe (that goes into the TBB), thus not allowing the fan to turn. If you need a TBB, get this one and save yourself a headache.
