This is a custom kit, complete with everything you need including couples, clamps, HKS SSQV BOV, AEM Dry Filter, Custom Short piping fabricated by Sasha at SG-Motorsport, and a Bings/Yonaka bigcore FMIC.
This kit would cost a lot of money to recreate if you had to for parts and the custom fabrication…
I’ll sell it here to the highest bidder. PM the price you think it’s worth.
ps - will not work with USDM s13 chassis as the piping will hit the headlight motors
