I'll break this down so you can understand.
JWT is an aftermarket company who specializes in Nissans. They make a pressure plate. You can buy it at
JIM WOLF TECHNOLOGY, INC. / NISSAN PERFORMANCE / NISSAN RACING /INFINITI PERFORMANCE.
B15 is a generation of Nissan Sentra that was sold with a SR20DE for 2 years and came with an improved clutch disc. Go to your local Nissan dealer and tell them you want to buy a clutch disc for a 2001 Sentra SE with a manual transmission.
See that's pretty easy right?
PS I hate it when people use that stupid texting language when they post. It only takes an extra 30 seconds to avoid looking like a moron in your posts.
