Ive got a couple of questions about the n75j valve.

That will probably make me sound really thick but here goes anyway...

Why is the n75j valve any different to the factory one it replaces??

Why does it need to be fitted in reverse?? (as recomended by Simon Coe of CCC Tech)

What will it do for my Upsolute chipped AGU 1.8t??
