Questions our customers have asked...

What size is this spacer?

Response: It is an angled spacer. 7/16th to 3/8th.

Wouldn't you need 2 oem plenum gaskets?? One for under the spacer and one for above it?

Response: We include one gasket specifically for the top of the spacer. We reuse the the lower metal gasket. If you wanted to add a fresh lower gasket we have them available here: (Link)

I bought this set a while back and now I cant seem to find the rubber pieces. I see you have the gasket priced at $28.00 which i will likely need but I also need the (6) M6 Washers w/ Bonded Seal. Are these sold separately? Are you guys able to source them?

Response: Hi Will thanks for the inquiry! We now have these available for online purchase at the link below. We have these in stock and ready to ship. Thanks for your patience! (Link)
