I Remember hearing about the Blitz around car shows and meets. This one is around the 2009 era. I like the looks but for my low boost supercharger setup so far it is not the sound I want. You can thank Greddy Type S on that. Video Coming soon.
To make this adapter work I had to drill mounting holes. I used the BOV with the Fastener bolts to mark the drilling location. First I drilled out for the threads to go through at ease. Next I taped off the larger drill bit so it would allow the head of the fastener to reseat in.
The adapter was made for the greedy fasteners bolt to thread in. So I enlarged them so the bolt would slide through at ease.
From 5 feet away from the BOV it measures 125 dB
