D16Y8
Installed on my turbo 96 civic with a D16Y8. Product came well packaged and all parts there. Some have said theirs was opened / installed before, Mine was sealed with plastic wrap and nothing was missing / opened. Install is super easy. 4mm allen for the top of the stud for install and a 12mm 12pt socket for torquing down the nuts.

Will never go without
To the person that lubed and installed the studs then removed them and returned to Amazon.. You Suck!I live in the Midwest with no access to any local places to get performance products. I had these studs delivered on a Saturday only to open the box and find this. I inspected the studs and they looked like they were installed in the block but never had the head installed. I had no choice but to use these and Amazon gave me back some of the money I paid for them.Amazing product shame the buying experience was not better.

D16y8 head stud
Building a d16y8 high compression motor and ARP head studs are the only way to go. All instructions are included minus the torque sequence.
