Default Bolt-on LS4 specific performance parts

Here is a list of performance parts for your LS4. This thread is based on bolt-on items that the typical gear head/backyard mechanic can do on their own.

A few notes!
I strongly recommend getting dyno tuned. Avoid canned tunes unless the tuner has away of data logging, and making corrections. A canned tune is nothing more then an assumption.

HP tuners and EFI live, is the best option, for the highly skilled. If you are considering using this advanced tuning software, then be prepared to learn at your own risk. I recommend searching https://ls1tech.com/forums/pcm-diagnostics-tuning-7/ for more information, and using forums on the manufactures website to gain incite.

Please understand, that I am not trying to be one sided. There are as many "bad" tuners as their are "good" so be cautious. I highly recommend using Diablosport tuners because of Lewis Eaton (Diablew). He is able to data log, and make the proper corrections.

Do not be affraid to use the search box. I have done my best at providing additional information.

So I've been trying to find a throttle body spacer for my 07 pontiac grand prix gxp. But all of the links on here won't bring me to a place to actually buy it. Does anyone know where to get one? Any help would be great. Thanks.
