    Wonderful product

    The spacer itself is a perfectly machined beauty. I did not receive any hardware, but a 5 minute trip to the hardware store and I was in business. This is an extremely minor issue for anyone making enough power to warrant an intake manifold with an oversized plenum.

    A word of caution, the 4mm Allen heads on such a long bolt (which have loctite on the threads) makes them exceptionally easy to strip. Take your time removing the bolts and you will do so without issue. When replacing the bolts with extended hardware, opt for those with 5mm Allen heads. Be sure to seal the threads upon re-assembly.

    All in all, a fantastic product well worth every penny.

    Wrong Hardware

    The extended bolts that were sent with the plenum space are too short. So now i have to source long enough bolts on my own because i do not feel l would get the correct ones in a timely manner.
    Other than that the product is amazing and beautiful. I can not wait to have it all installed.

    Skunk2 plenum spacer.

    Great looking product, and fits good... if it wasn't for the fact that the supplied bolts were 10mm too short. Really not a big problem, but I you buy a simple spacer for more than $100 you would think that the supplied hardware should be correct.
