Anyone know the size of the nipple on a HKS Super Squential BOV? Im trying to peice together a hose and some fittings to hook it up. Thx

 

should be std 1/8npt but not 100% positive have you tried just a std 1/8npt

 

Its the same vaccume line as you use for FPR, I still put zipties on all connections thought...

 

4mm

 

i called HKS and the guy was very rude and didnt know. He finally asked and said it was 6mm and I knew that wasnt right as thats way too big. I think thats OD and I think lazerus is right, 4mm has to be ID.

Viren Its not a NPT fitting as it has a nipple built into the bov case.

Thanks for the responses! I love Honda-tech!

 

What about the size of the two vacuum ports on a 38mm TiAL wastegate? They look about 1/4" NPT but the included fittings aren't tapered. I need to buy a shorter fitting to clear my hood.
